top(1): Migrate top to usr.bin
We've been maintaining top(1) for a long time, and the upstream hasn't existed/been used in similarly as long. Make it clear that we own top(1) Tested with 'make universe'. Everything passed except MIPS which failed for unrelated reasons. Install also tested for amd64.

Thu Mar 30 2000 - wnl (3.5beta12)
|
||||
Updated modules: m_aix41.c, m_aix43.c, m_mtxinu.c, m_sco5.c,
|
||||
and m_ultrix4.c.
|
||||
Included m_irixsgi.c from some source that's been floating around
|
||||
SGI. Don't yet know how it compares to m_irix62.
|
||||
|
||||
Fri Mar 10 2000 - wnl (3.5beta11)
|
||||
top.c: avoid potential loop if stdout gets closed, use macro
|
||||
for p_active to avoid collision with system macros.
|
||||
m_sunos5: widened some fields to accomodate 5.8.
|
||||
m_decosf1: added ordering support
|
||||
m_irix62_64: provides 64-bit module based on m_irix62.
|
||||
m_irix62: skip bogus files in /proc directory
|
||||
m_svr42MP and m_svr5: complete replacement with updated copies
|
||||
m_mtxinu: complete replacement with updated copies
|
||||
m_aix43: new module for 4.3
|
||||
getans: replaced with a Bourne shell script
|
||||
|
||||
Mon Mar 6 2000 - wnl (3.5beta10)
|
||||
m_sunos5.c: workaround for curses bug: ensure that TERMINFO has
|
||||
a value.
|
||||
|
||||
Fri Jan 15 1999 - wnl (3.5beta10)
|
||||
top.c: now check return code from read to avoid looping on eof.
|
||||
top.c: delay of 0 now only valid for root.
|
||||
decosf1.c: patches from Rainer Orth should fix most of the
|
||||
problems with this module (including the display of certain
|
||||
processes and runtime errors).
|
||||
sunos5.c: Rainer insisted on putting the slash back in the
|
||||
state field ("run/4") and widened the field to accomodate it.
|
||||
aix.c: widened PID field for 6-digit pids (shortened NICE field)
|
||||
module macosx added, thanks to Andrew Townley.
|
||||
|
||||
Fri Dec 18 1998 - wnl (3.5beta9)
|
||||
Configure checks status of "make" and complains if it fails.
|
||||
|
||||
Thu Dec 17 1998 - wnl (3.5beta9)
|
||||
Added module sco5 from Mike Hopkirk.
|
||||
Added module netbsd132 from moto kawasaki.
|
||||
|
||||
Sun Oct 25 1998 - wnl (3.5beta9)
|
||||
Added Casper's patches for sunos5 for the following:
|
||||
produce same results as swap -s (5.5 and higher),
|
||||
don't use system_pages kstat when /dev/kmem can be opened,
|
||||
skip . and .. when reading /proc, replace use of SOLARIS24
|
||||
with OSREV.
|
||||
|
||||
Fri Sep 11 1998 - wnl (3.5beta9)
|
||||
Added workaround to getans for the absence of $< in SCO Unix.
|
||||
|
||||
Wed Jul 1 1998 - wnl (3.5beta9)
|
||||
Changed structure member "errno" to "errnum" in commands.c.
|
||||
Replaced hpux10 module with one from John Haxby.
|
||||
|
||||
Fri Apr 17 1998 - wnl (3.5beta8)
|
||||
Moved definition of _KMEMUSER earlier in m_sunos5.c. This should
|
||||
fix the compilation problem with gnu 2.7.2.3, obviating the need
|
||||
for the fixinc.svr4 patch, but hopefully will not affect anything
|
||||
else.
|
||||
Added -DORDER to m_sunos4mp.c
|
||||
|
||||
Tue Nov 18 1997 - wnl (3.5beta7)
|
||||
Added gcc 2.7.2.3 patch for fixinc.svr4 and changed INSTALL and
|
||||
FAQ to refer to it.
|
||||
Added NetBSD HP9000 fix. Hopefully it doesn't break other
|
||||
NetBSD platforms.
|
||||
|
||||
Fri Oct 24 1997 - wnl (3.5beta7)
|
||||
Modified m_dcosx.c to change uses of procdir to xprocdir, avoiding
|
||||
a name clash with an include file (Bryn Parrott)
|
||||
|
||||
Sat Oct 11 1997 - wnl (3.5beta6)
|
||||
Incorporated Casper's patches for Solaris 2.6 and for the multi-
|
||||
processor bug ("kstat finds too many cpus").
|
||||
|
||||
Sun Jan 20 1996 - wnl (3.5beta5)
|
||||
Fixed Casper's m_sunos5 module: there was a poor interaction with
|
||||
his use of OSREV and SunOS 5.5.1.
|
||||
|
||||
Fri Dec 20 1996 - wnl (3.5beta4)
|
||||
Replaced m_sunos5 with a reworked version by Casper Dik. This one
|
||||
should work under 2.6 and may not require that top be run setuid
|
||||
to root under 2.5 or 2.6. This also fixed a bug in m_sunos5 that
|
||||
was introduced in beta3.
|
||||
Fixed calculation of OSREV in Configure.
|
||||
|
||||
Wed Nov 20 1996 - wnl (3.5beta3)
|
||||
Incorporated contributed fixes to: bsdos2, irix62, freebsd20,
|
||||
ultrix4, sunos5. Changed calculation of swap area in sunos5 (now
|
||||
uses swapctl). sunos5 now understands idled processors. Changed
|
||||
Configure to determine os revision using uname (when available)
|
||||
and adding it to machine.c compiliation in Makefile as -DOSREV.
|
||||
Changed calls to "exit" in modules to use "quit" instead.
|
||||
|
||||
Oct 20 1996 - wnl (3.5beta3)
|
||||
Removed "time" from list of ordering choices: there's no easy way
|
||||
to get cpu time for all processes (it's in the u area).
|
||||
|
||||
Fri Oct 18 1996 - wnl (3.5beta3)
|
||||
hpux10 and hpux9: using a better means for determining when a
|
||||
process is idle.
|
||||
decosf1 now includes utils.h.
|
||||
|
||||
Fri Sep 13 1996 - wnl (3.5beta2)
|
||||
Fixed Configure to build Make.desc in such a way that doesn't
|
||||
require a long argument to sed.
|
||||
|
||||
Thu Sep 12 1996 - wnl (3.5beta2)
|
||||
Fixed bug in display.c that affected empty cpustate names.
|
||||
Created hpux1010 module - a variant of hpux10 that does not use
|
||||
struct proc or struct user (suitable for HP/UX 10.10).
|
||||
|
||||
Wed Sep 11 1996 - wnl (3.5beta2)
|
||||
Changes to sunos5 module: Removed WCPU column since it is meaningless
|
||||
on a SVR4-based system. Added THR column to show number of threads
|
||||
for each process. This was not straightforward: the information is
|
||||
not stored in prpsinfo but rather in prstatus.
|
||||
|
||||
Tue Sep 10 1996 - wnl (3.5beta1)
|
||||
Added patches for sunos4mp to provide order support.
|
||||
Added irix62 module.
|
||||
Changed prime.c to include stdio.h for printf prototype.
|
||||
Added conditional code to os.h and utils.c to handle systems
|
||||
where sys_errlist is defined in stdio.h (such as NetBSD).
|
||||
|
||||
Mon Sep 09 1996 - wnl (3.5beta1)
|
||||
Removed tar and shar rules from Makefile.X -- don't need them anymore.
|
||||
Added -v option to display version number. Updated man page.
|
||||
|
||||
Thu Aug 29 1996 - wnl (3.4)
|
||||
Replaced modules (from Tim Pugh): next 32, next40.
|
||||
Fixed bug in username.c: hashing negative uids.
|
||||
|
||||
Thu Aug 22 1996 - wnl (3.4beta3)
|
||||
Patched modules: ultrix4, sunos4, sunos5, utek, decosf1, irix5.
|
||||
Added modules: next40, next32.
|
||||
Fixed procstates update bug in display.c.
|
||||
Fixed divide by zero bug in utils.c.
|
||||
Fixed bad number in layout.h
|
||||
Minor fixes to Configure.
|
||||
Complete overhaul of FAQ.
|
||||
|
||||
Tue Feb 13 1996 - wnl (3.4beta3)
|
||||
Added convex module from Warren Vosper (originally written by
|
||||
William Jones).
|
||||
|
||||
Tue Feb 13 1996 - wnl (3.4beta2)
|
||||
Fixed format_k in utils.c to calculate K and M values correctly.
|
||||
Added check for gigabyte values ('G'). Changed sumamry_format
|
||||
in display.c to use format_k where appropriate.
|
||||
Changed creation of distribution tar file to place everything in
|
||||
a top level directory.
|
||||
|
||||
Tue Jan 30 1996 - wnl (3.4beta2)
|
||||
Added m_aix41 module. Added new tag type to module comments:
|
||||
TERMCAP, which defined the library to use for a termcap library.
|
||||
If no TERMCAP tag is found in the module's initial comment, then
|
||||
Configure will default to "-ltermcap". AIX needs this since it
|
||||
put all the termcap routines in libcurses(!)
|
||||
|
||||
Added m_bsdos2 (found lingering in my mailbox).
|
||||
Updated m_svr4 to include support for NCR multiprocessors.
|
||||
Fixed small bug in utils.c
|
||||
|
||||
Thu Jan 25 1996 - wnl (3.4beta1)
|
||||
Fixed m_sunos5 invocation of gettimeofday to include "NULL" as
|
||||
second argument. This provides compatability with the Posix-
|
||||
compliant template provided with SunOS 5.5, but doesn't hurt
|
||||
previous versions since they do bother with a template for that
|
||||
function.
|
||||
|
||||
Made changes (recommended by net users) to hpux10, ultrix4,
|
||||
netbsd10, aux3 (replaced aux31). Added module for linux.
|
||||
|
||||
Fri Oct 10 1995 - wnl (3.4beta1)
|
||||
Added user-contributed modules for SCO Unix, IRIX 5, HP/UX 10,
|
||||
Pyramid DC/OSX. Changed Configure so that it runs in environments
|
||||
whose c-shells have no 'eval'(!). Added support for multiple sort
|
||||
ordering methods via the -o switch. This option requires support
|
||||
from the machine dependent module: such support was added to
|
||||
sunos5 (thus sunos54) and sunos4.
|
||||
|
||||
display.c: Changed CPU states display line to shorten the leading
|
||||
tag if the data won't fit in the current width. Fixed a divide-by-
|
||||
zero bug that affected ultrasparc servers (and potentially other
|
||||
systems).
|
||||
|
||||
m_sunos5.c: Now asks the system for the correct pagesize rather than
|
||||
assuming it is 4K.
|
||||
|
||||
Thu Mar 2 1995 - wnl (3.3 RELEASE)
|
||||
Added module netbsd10 and renamed netbsd to netbsd08. Changed
|
||||
Configure so that it does not use an initial default module name.
|
||||
Made other compatability fixes to Configure. Added comments to
|
||||
decosf1 concerning optimizer bug. Other documentation changes.
|
||||
Added use of "prime.c" to Configure script.
|
||||
|
||||
Tue Feb 7 1995 - wnl (3.3beta6)
|
||||
Still one more beta....
|
||||
Fixes for sunos5 2.4 gcc core dump (it was an alignment problem).
|
||||
Fixed and improvements for decosf1 (including use of format_k
|
||||
for proper SIZE column formatting). Added modules freebsd20 and
|
||||
ncr3000.
|
||||
|
||||
Thu Feb 2 1995 - wnl (3.3beta5)
|
||||
One more beta....
|
||||
Fixed a few bugs in the sunos5 port pertaining to casting and
|
||||
very large memory counts. Added "ifndef HAVE_GETOPT" to getopt.c
|
||||
to provide for conditional compilation of the getopt function.
|
||||
Those systems that have getopt in libc can add -DHAVE_GETOPT to
|
||||
the CFLAGS line in the module to prevent the function from being
|
||||
compiled. Added sunos54 module to accomodate SunOS 5.4
|
||||
peculiarities. Added module for aux3.1.
|
||||
|
||||
Wed Jan 4 1995 - wnl (3.3beta4)
|
||||
This is really taking too long......sigh.
|
||||
Fixed SIGWINCH handling once and for all. It now remembers the
|
||||
number of processes you want displayed even thru window resizes.
|
||||
Fixed buffer conflict in utils.c (itoa and itoa7).
|
||||
Lots of small improvements to the various modules were made over
|
||||
the past month: too numberous to list here. SunOS 5 module made
|
||||
more secure thru use of seteuid calls (other SVR4 modules should
|
||||
be modified similarly). One final MP fix to sunos5, too. Module
|
||||
for decosf1 was modified to accomodate V3.0.
|
||||
|
||||
Mon Apr 18 1994 - wnl (3.3beta3)
|
||||
I think I finally got a sunos5 module that will work on MP
|
||||
machines. Fixed cpu states figure in osmp41a so that
|
||||
percentages never exceed 100%. Added shell script "install"
|
||||
since Unix vendors can't seem to make up their minds on what
|
||||
options they want to use for the one that comes with the OS.
|
||||
Added netbsd modules from Christos. Fixed lots of other little
|
||||
things over the past few months that I have long since forgotten.
|
||||
|
||||
Wed Dec 15 1993 - wnl (3.3beta2)
|
||||
Added module patches from various users: hpux9, sunos5.
|
||||
Fixed bug with batch mode (screen_width wasn't getting set).
|
||||
Changes to accomodate 64 bit machines.
|
||||
Fixed some bugs in command parsing ("renice 19 " did something
|
||||
unexpected).
|
||||
|
||||
Mon Aug 30 1993 - wnl (3.3beta)
|
||||
Added lots of little patches from various users.
|
||||
Added routines to utils.c for intelligent formatting of kilobytes
|
||||
and time. These are intended to be used in the modules when
|
||||
formatting a process line. Added code to "summary_format" in
|
||||
display.c to do intelligent formatting of memory quantities.
|
||||
Redid display.c to allow for varying line widths and dynamic
|
||||
reallocation of the screen buffer.
|
||||
Added a SIGWINCH handler to top.c!
|
||||
Added a constant, MAX_COLS, to top.h which defines the absolute
|
||||
widest line we will ever allow. Changed allocations of "char fmt"
|
||||
in all machine modules to use this constant rather than an abitrary
|
||||
number.
|
||||
|
||||
Fri Aug 13 1993 - wnl (3.3)
|
||||
Changed return value definition of time-related functions in top.c,
|
||||
display.c, and m_ultrix4.c to time_t (stuart@coral.cs.jcu.edu.au).
|
||||
Fixed bug in display.c: line_update when start != 0.
|
||||
|
||||
Wed Aug 4 1993 - wnl (3.2 release)
|
||||
Changes to Configure from Paul Vixie. Added modules for hpux9 and
|
||||
bsd386.
|
||||
|
||||
Tue Jul 13 1993 - wnl (3.1 release)
|
||||
More small changes and minor bug fixes. Brought bsd44 up to date
|
||||
and added a module for svr4.2. Changed shar packaging to use Rich
|
||||
Salz's cshar stuff.
|
||||
|
||||
Wed Jul 7 1993 - wnl (3.1BETA)
|
||||
More changes and bug fixes to Configure. Applied some other
|
||||
minor bug fixes and suggestions from the beta testers. Added
|
||||
the "metatop" shell script and the "installmeta" rule to the
|
||||
Makefile to make handling multiple machine models and OS versions
|
||||
easier. Added INSTALL and FAQ files.
|
||||
|
||||
Tue May 18 1993 - wnl (3.1BETA)
|
||||
Changed Configure to be compatible with most SVR4 environments
|
||||
(differing output from "ls -lg"). Also changed Configure,
|
||||
Makefile.X, etc., to look for module files in the subdirectory
|
||||
"machine" (thanks to Christos Zoulas).
|
||||
|
||||
Tue Apr 20 1993 - wnl (3.1BETA)
|
||||
Changed both occurences of "ls -1" in Configure to "ls". This
|
||||
SHOULD produce the same result, and has the advantage that it
|
||||
doesn't produce an error on a system 5 machine. Integrated other
|
||||
changes recommended in the first round of beta testing.
|
||||
|
||||
Wed Mar 10 1993 - wnl (3.1BETA)
|
||||
MAJOR CHANGE: I have added a required function to all machine
|
||||
dependent modules, called proc_owner. It takes a pid as an argument
|
||||
and returns the uid of the process's owner. Such capability is
|
||||
necessary for top to run securely as a set-uid program, something
|
||||
that is needed for SVR4 implementations to read /proc. I have
|
||||
retrofitted all modules except dgux with this function, but was
|
||||
not able to test most of them. Top should now run securely as
|
||||
a setuid program. Added 386bsd and sunos5 modules. Added sunos4mp
|
||||
module for MP Suns.
|
||||
|
||||
Sat Feb 20 1993 - wnl (3.1ALPHA)
|
||||
Modified top.c and commands.c to compile correctly on System V
|
||||
derived Unixes (especially SVR4), but in a way that doesn't rely
|
||||
on an oracle-like declaration (that is, I don't use "ifdef SYSV").
|
||||
Fixed some bugs in "Configure" and "getans". Added inspection of
|
||||
env variable "TOP" for options, and made -I default to showing
|
||||
idle processes. Added "u" command to change username restriction
|
||||
on the fly. Created shell script "suntop" for poor multi-version
|
||||
SunOS folks (like myself).
|
||||
|
||||
Wed Jun 3 1992 - wnl (3.0)
|
||||
"max_topn" wasn't being used everywhere it was supposed to be
|
||||
in top.c. Many cosmetic changes, including copyright notices in
|
||||
all the .c files. Version number is now handled by version.c and
|
||||
reflects the current patchlevel (which is initially set to 0).
|
||||
Changed Configure and Makefile to allow configurable variables for
|
||||
certain commands: shell, cc, awk, install. Updated README and
|
||||
Porting. Ready to release to the world!
|
||||
|
||||
Mon May 18 1992 - wnl (2.9BETA)
|
||||
Added modules provided by Christos Zoulas. Replaced screen.c
|
||||
with one modified by Christos and that will appropriately select
|
||||
and handle the sgtty, termio, or termios system. Integrated many
|
||||
other changes recommended by Christos. Fixed (I hope) the "-b"
|
||||
batch mode display bug. Had to change loadavg to load_avg to avoid
|
||||
a conflict with 4.4BSD.
|
||||
|
||||
Mon Apr 27 1992 - wnl (2.8BETA)
|
||||
Added modules provided by Daniel Trinkle. Added patchlevel.h,
|
||||
but the patch level is not yet reflected in the version number.
|
||||
Cleaned up m_sunos4.c a little.
|
||||
|
||||
Wed Apr 22 1992 - wnl (2.8BETA)
|
||||
Major internal reorganization. All of the system dependent stuff
|
||||
is now really and truly separated from everything else. The
|
||||
system dependent functions are contained in a separate .c file
|
||||
called a "module". The Configure script knows how to find and
|
||||
set up these modules, but the human installer still needs to tell
|
||||
Configure which module to use (no automagic determination of
|
||||
machine type---sorry). Added -U option to specify one user's
|
||||
processes, but there is no corresponding command...yet. Other
|
||||
changes and improvements too numerous to mention here. Currently
|
||||
there are only two modules: sunos4 and umax. But after this beta
|
||||
release is sent around, I expect more to be written. I just hope
|
||||
that the machine-dependent abstractions don't need to change in
|
||||
the process.
|
||||
|
||||
Thu Mar 26 1992 - wnl (2.7BETA)
|
||||
Beta release with minimal architecture support. Updated README
|
||||
and added a first cut at a Porting guide. Added ioctl TIOCGWINSZ
|
||||
code from top2.5+ (courtesy of David MacKenzie). I didn't even
|
||||
try porting the Ultrix support since I don't have access to an
|
||||
Ultrix machine.
|
||||
|
||||
Fri Oct 11 1991 - wnl (2.6)
|
||||
This version was not widely released. It contained many changes.
|
||||
Here are the major ones:
|
||||
|
||||
Put in Vixie's idle process hack.
|
||||
|
||||
Enhanced type field in new_message to handle delayed messages.
|
||||
|
||||
Changed u_process to automatically adjust for varying lines of
|
||||
output. Management of screenbuf should now be completely contained
|
||||
in display.c. Removed now extraneous code from CMD_number[12]
|
||||
portion of command switch in top.c. This was the stuff that dealt
|
||||
with zeroing out lines in screenbuf.
|
||||
|
||||
Finally made it all work correctly on a 386i. Problems I had to
|
||||
overcome: kvm_nlist doesn't return 0 on success as advertised (it
|
||||
returns 1 instead); the results of a kvm_nlist are different
|
||||
(n_type can be zero even for a symbol that exists).
|
||||
|
||||
Serious rearrangement for processor dependent stuff. All nlists
|
||||
are now in separate files with the suffix ".nlist". Most machine
|
||||
specific code is in "machine.c" surrounded by appropriate ifdefs---
|
||||
the goal is to eventually have all machine specific code in this
|
||||
file. Managed to find a way to detect SunOS 4.x at compile-time:
|
||||
this is contained in the include file "sun.h". Completely changed
|
||||
the memory display line for SunOS 4.x---it now displays a far
|
||||
more appropriate report.
|
||||
|
||||
Created the shell script "Configure" to aid in the configuration
|
||||
step.
|
||||
|
||||
Fixed a bug in init_termcap: it will now tolerate an environment
|
||||
which does not have TERM defined (thanks to Sam Horrocks for
|
||||
pointing this out).
|
||||
|
||||
Tue Aug 9 1988 - wnl (2.5)
|
||||
Added changes to make top work under version 4.0 of the Sun
|
||||
operating system. Changes were provided by Scott Alexander of the
|
||||
University of Pennsylvania. Thanks! Compile with "-Dsunos4" to
|
||||
get them. Virtual memory statistics are not readily accessible
|
||||
under 4.0, so they don't show up in the output.
|
||||
|
||||
Thu Jul 31 1987 - wnl (2.4)
|
||||
Fixed a problem with the 4.0 Pyramid code. The label "cp_time"
|
||||
doesn't exist in the 4.0 kernel anymore. I think the code Carl
|
||||
sent me wants "percpu" instead. That is what I am using and it
|
||||
appears to work. 375 code is still untested (at least by me).
|
||||
Also picked a great deal of lint out of the source. Lint now only
|
||||
complains about a very few nitpicky things (there are far too many
|
||||
calls to "printf" to put a "(void)" in front of!), at least under
|
||||
SunOS.
|
||||
|
||||
Tue Jul 28 1987 - wnl (2.4a)
|
||||
Added changes for a Symmetrics Computer Systems s/375 machine.
|
||||
Changes were provided by Paul Vixie. Thanks! According to Mr.
|
||||
Vixie: "These changes were not made at, by, or for SCS proper.
|
||||
SCS would probably be interested in them, but so far only the
|
||||
users' group has them. They were made in February, 1987, to
|
||||
version 2.1 of the program, by Paul Vixie
|
||||
(dual!ptsfa!vixie!paul@ucbvax.Berkeley.EDU)." His changes were
|
||||
integrated into version 2.3 to make version 2.4.
|
||||
|
||||
The SCS peculiarities are summarized in Changes.scs.
|
||||
|
||||
Tue Jun 9 1987 - wnl (2.3 for real)
|
||||
Changed the includes for the extra code Carl sent me to only
|
||||
compile on Version 4.0 Pyramid machines. This makes top still
|
||||
compilable on pre-4.0 Pyramids. Specifically, this code is only
|
||||
compiled when both "pyr" and "CPUFOUND" are defined.
|
||||
|
||||
Wed Jun 3 1987 - wnl (2.3 with Pyramid additions)
|
||||
It's been a month and I still haven't done anything about
|
||||
distributing this version. However, Carl Gutekunst from Pyramid
|
||||
has sent me some extra patches for some of the Pyramid code. I
|
||||
just added those and will make them part of 2.3. This fixes the
|
||||
following Pyramid problems: adds the inclusion of <sys/systm.h>,
|
||||
uses the correct size for getting the kernel value _ccpu (this bug
|
||||
affected the Vax version as well), sums the elements of the percpu
|
||||
array to calculate a cp_time value (for OSx 4.0).
|
||||
|
||||
Fri May 1 1987 - wnl (2.3)
|
||||
I have finally finished all the changes for better support of
|
||||
oddbal terminals. Added the low-level routine "clear_eol" which
|
||||
makes handling terminals without "ce" easy: it uses spaces
|
||||
instead. All direct uses of "clear_line" outside of screen.c have
|
||||
been changed to use this primitive. A terminal with "os" is now
|
||||
handled in such that all situations that need overwriting are
|
||||
completely avoided (including several commands). This required
|
||||
some changes to the way commands are translated into action (in
|
||||
"top.c"). Made several important changes to display.c to prevent
|
||||
overflowing of any of the fields. Specifically, more than 99
|
||||
total processes and a cpu state that reaches 100%. Had to make a
|
||||
small change to two casts in top.c, because the Sun 3.2 compiler
|
||||
was giving warnings on them. Added the "-q" option which lets
|
||||
root run top at a nice of -20 (in case he thinks he really needs it).
|
||||
|
||||
Tue Dec 30 1986 - wnl (2.2)
|
||||
I think I fixed a bug reported by Julian Onions at Nottingham.
|
||||
Occasionally, top will core dump when the sprintf in either
|
||||
i_process or u_process overflows due to an exceptionally
|
||||
unrealistic time value. I think it highly unlikely that top can
|
||||
get a bad proc structure (although I suppose it is possible), but
|
||||
the process time is read from the user structure, and that can
|
||||
sometimes be part garbage. So, "get_ucpu" checks the value it
|
||||
returns to make sure its formatted form will not overflow the
|
||||
sprintf. If this doesn't fix the bug, then more drastic measures
|
||||
will be necessary. I plan to make this version the official
|
||||
"top 2.2". [[ This version was never distributed very widely. ]]
|
||||
|
||||
Tue Dec 2 1986 - wnl (2.2c)
|
||||
Added to top.c the notion of a "failed command". When a command
|
||||
produces a message (on the message line), an update does not
|
||||
follow it. Before, the message was written and a new display was
|
||||
shown---purposefully not overwriting the message. But the
|
||||
improvements to handle overstriking terminals and terminals
|
||||
without "ce" clear the screen before every display, which would
|
||||
erase the message. Now, the message is displayed and top waits
|
||||
another full time interval before updating the display. This
|
||||
works much better all around.
|
||||
|
||||
Mon Nov 24 1986 - wnl (2.2b)
|
||||
Created a new file, utils.c, and made appropriate changes to
|
||||
Makefile. This new file holds all utility functions that can and
|
||||
may be used by more than one "module". Improved i_memory and
|
||||
u_memory (display.c) so that screen updates for the values
|
||||
displayed are only changed when necessary. Also made the line
|
||||
look better: the last fixes made for a rather ugly display.
|
||||
Added the locally defined constant "LoadMax" and added code to
|
||||
top.c to send the cursor home after a space command is entered if
|
||||
the load average is higher than "LoadMax". This provides visual
|
||||
feedback on loaded systems.
|
||||
|
||||
Mon Nov 3 1986 - wnl (2.2a)
|
||||
Widened the format for memory usage so that it can display 5
|
||||
digits. This makes that line look a little ugly---maybe I'll fix
|
||||
that later. Screen handling now understands "os" and a missing
|
||||
"ce". It treats them identically: clear the screen between each
|
||||
display. Screen handling code now uses "cd" when appropriate
|
||||
(i.e.: when user has shortened the screen). Made i_loadave clear
|
||||
then screen and took out most of the explicit calls to "clear" in
|
||||
top.c. This method is cleaner, especially in conjunction with
|
||||
"os" handling. Added preprocessor variable "RANDOM_PW" for
|
||||
systems that access the passwd file randomly (Sun's yp and 4.3).
|
||||
With "RANDOM_PW" set, "getpwuid" is used instead of "getpwnam",
|
||||
but uid->username mappings are still hashed internally (because
|
||||
that is still faster than going to disk).
|
||||
|
||||
Mon Oct 6 1986 - wnl (2.1)
|
||||
A bug with the kill command was pointed out by "dciem!tim"---
|
||||
specifying a signal by name did not work correctly. This bug has
|
||||
been fixed with a simple change to commands.c. Another bug made
|
||||
the cpu state percentages incorrect the first time they were
|
||||
displayed. This bug has also been fixed (changed top.c).
|
||||
|
||||
Thu Sep 4 1986 - wnl (2.0, at last)
|
||||
This is the version that will (hopefully) get released to the
|
||||
world as top 2.0.
|
||||
Added the "r" and "k" commands for renice and kill, respectively.
|
||||
This required adding a way to handle system call errors, and the
|
||||
addition of the "e" command. Help screen and manual page were
|
||||
changed to reflect this change. Changed all "#ifdef SUN" directives
|
||||
to "#ifdef sun", and changed all "#ifdef PYRAMID" directives to
|
||||
"#ifdef pyr". As much as I hate those choices of preprocessor
|
||||
names (they too easily conflict with real variable names), it does
|
||||
make automatic compilation possible---people don't have to change
|
||||
the Makefile anymore for specific machines. The manual page was
|
||||
changed to automatically incorporate the defaults as set in the
|
||||
Makefile (including an infinite value for TOPN) and the way the
|
||||
manual page is generated by the Makefile was changed to make
|
||||
maintenance of this information automatic.
|
||||
|
||||
Mon Jul 28 1986 - wnl (still pre 2.0)
|
||||
Real close now. I put in a new definition for the macro "pagetok"
|
||||
that does an explicit shift of a constant expression involving
|
||||
PGSHIFT. Appropriate checks are made if PGSHIFT is to small.
|
||||
"pagetok" is now used exclusively everywhere to convert kernel
|
||||
clicks to kilobytes. I added a full blown interactive mode with
|
||||
the ability to change some of the runtime parameters (how many to
|
||||
display, time delay, etc.) while top is running. I also
|
||||
incorporated a few ideas from the net: control characters in the
|
||||
command name are replaced with '?'; the '-S' option makes the
|
||||
swapper and pager visible; options have been added to control the
|
||||
number of displays produced (this makes it easier to make
|
||||
performance snapshots with top). I have also added the notion of
|
||||
"infinite" values for number of processes and number of displays.
|
||||
I fixed a long-standing bug in the uid to username mapping code
|
||||
that was only aggravated on the pyramids: it was an ill-defined
|
||||
expression (akin to i = i++). I tweaked the proc_compar routine
|
||||
for qsort slightly so that stopped processes were more likely to
|
||||
show up. Manual page was updated to reflect all changes
|
||||
noticeable to the user.
|
||||
|
||||
Tue Jul 1 1986 - wnl (pre 2.0 -- 1.9999?)
|
||||
In the process of major revamping on the way to version 2.0.
|
||||
I have completely done away with curses by adding my own screen
|
||||
management routines in a separate file (screen.c). The rationale
|
||||
for this is that top knows a whole lot more about what is and is
|
||||
not redundant on the screen and can compare simple integer values
|
||||
where curses would have to compare strings. This has turned out
|
||||
to be a very big win speed-wise. The proc_compar routine for
|
||||
sorting has been rewritten to include several more keys. I
|
||||
decided this was necessary when I noticed that the "top" process
|
||||
itself kept disappearing off the top 10 list on a Sun-3. All the
|
||||
processes had the same percentage (0%) and the sort wasn't really
|
||||
doing anything worthwhile. I changed the expression that computes
|
||||
memory usage to use the ctob macro instead of just assuming that
|
||||
pages were 512 bytes. More work still needs to be done before
|
||||
this version is usable. I changed options-processing to use
|
||||
getopt and added appropriate incantations to the Makefile.
|
||||
|
||||
Wed Feb 20 1985 - wnl (still 1.8)
|
||||
Put in the ifdef FOUR_ONE statements to make top still compilable
|
||||
on a 4.1 system. Apparently, there are some users out there that
|
||||
need this functionality. Oh well. I don't guarantee any of it,
|
||||
since I can't test it. Made appropriate changes to README and
|
||||
final installation related changes to Makefile.
|
||||
|
||||
Sat Feb 2 1985 - wnl (1.8)
|
||||
Removed all the ifdef FOUR_TWO statements and made "top" into a
|
||||
4.2 only program. If someone really wants to still run it on 4.1,
|
||||
then they can do all the work. We don't have a 4.1 machine
|
||||
anymore, so I don't even know if the thing still works under 4.1.
|
||||
Cleaned up the Makefile and the README. Added installation rules
|
||||
to the Makefile, as requested by several sites. Fixed a very
|
||||
obscure divide-by-zero bug. Added a second "key" to the qsort
|
||||
comparison function (proc_compar) so that comparisons are based on
|
||||
cpu ticks if the percentages are equal (provided by Jonathon
|
||||
Feiber at Sun).
|
||||
|
||||
Tue Dec 11 1984 - wnl (1.7)
|
||||
Added the virtual and real memory status line to the header area
|
||||
(provided by Jonathon Feiber at Sun)
|
||||
|
||||
Tue Nov 20 1984 - wnl (1.6)
|
||||
Added an "exit" if sbrk's fail. Added changes from Jonathon
|
||||
Feiber at Sun: ifdef SUN to make top work on Suns (they don't use
|
||||
doubles in the proc structure), register declarations, check for
|
||||
getting a user structure that has disappeared since the proc array
|
||||
was read (it used to die, now it just shows the process as swapped).
|
||||
|
||||
Tue Nov 13 1984 - wnl (1.5)
|
||||
If the number of displayable processes ("active_procs") was less
|
||||
than the number of requested processes ("topn"), top would
|
||||
segmentation fault. This bug has been fixed. Thanks to Prentiss
|
||||
Riddle at ut-sally for pointing out the existence of this bug.
|
||||
|
||||
Tue Oct 23 1984 - wnl (1.4)
|
||||
Finally fixed the hash table bug that caused processes owned by
|
||||
root to sometimes appear with either no name or a different name
|
||||
that had UID 0 (such as "operator"). Removed all the ifdef DEBUG
|
||||
blocks to make top ready for distribution to the real world.
|
||||
|
||||
Sun Apr 8 1984 - wnl (still 1.3)
|
||||
Made some slight changes to the display format. It now looks more
|
||||
aesthetically pleasing. Added some preprocessor constants so that
|
||||
the two defaults (number of processes and seconds of delay) easier
|
||||
to change.
|
||||
|
||||
Thu Apr 5 1984 - wnl (1.3)
|
||||
Changed the order in which things are done at initialization time.
|
||||
This way, if an error occurs before starting the main loop, curses
|
||||
will never get started. Also changed other error handlers so that
|
||||
endwin() is called before any flavor of exit. Specifying a number
|
||||
of processes that is more than the screen can handle is no longer
|
||||
fatal. It displays a warning message and pretends the user
|
||||
specified the maximum for the screen. Finally cured all the TSTP
|
||||
blues (well, almost all). I removed my TSTP handler and convinced
|
||||
the system to always use the one that curses sets up. Turns out
|
||||
that "sleep" was stepping all over it during a pause. So, I don't
|
||||
use sleep anymore. The only problem that remains with it now is
|
||||
redrawing the old display before updating it after a pause.
|
||||
|
||||
Tue Apr 3 1984 - wnl (from 1.0 to 1.2)
|
||||
I changed the format of the TIME column from just "seconds" to
|
||||
"minutes:seconds". I also made pausing work correctly. Screen
|
||||
redraws with an up to date display. For compatibility with 4.2, I
|
||||
changed the name of the "zero" function to "bzero". The makefile
|
||||
has been altered to handle versions for 4.1 and 4.2, and README
|
||||
has been updated to reflect these recent changes.

||||
First we need to find out a little bit about the executables needed to
|
||||
compile top.
|
||||
|
||||
'EOF'
|
||||
./getans "What is the full path name for the Bourne shell" file "$Cmdshell" .$$
|
||||
set Cmdshell = `cat .$$`
|
||||
|
||||
cat <<'EOF'
|
||||
|
||||
Please supply the name of the appropriate command. It need not be a
|
||||
full path name, but the named command does need to exist somewhere on
|
||||
the current path.
|
||||
|
||||
'EOF'
|
||||
./getans "AWK Interpreter" path "$Cmdawk" .$$
|
||||
set Cmdawk = `cat .$$`
|
||||
./getans "C Compiler" path "$Cmdcc" .$$
|
||||
set Cmdcc = `cat .$$`
|
||||
|
||||
cat <<'EOF'
|
||||
|
||||
The installer command needs to understand Berkeley-esque arguments:
|
||||
"-o" for owner, "-g" for group, and "-m" for mode. A shell script
|
||||
called "install" is distributed with top and is suitable for use by
|
||||
top. You can specify a different program here if you like, or use
|
||||
the shell script (the default).
|
||||
|
||||
'EOF'
|
||||
./getans "Installer" path "$Cmdinstall" .$$
|
||||
set Cmdinstall = `cat .$$`
|
||||
|
||||
cat <<EOF
|
||||
|
||||
What other options should be used with the $Cmdcc command (use "none" to
|
||||
specify no options)?
|
||||
EOF
|
||||
./getans "Compiler options" string "$cdefs" .$$
|
||||
set cdefs = `cat .$$`
|
||||
if ("$cdefs" == "none") then
|
||||
set cdefs = ""
|
||||
endif
|
||||
|
||||
cat <<'EOF'
|
||||
|
||||
Now you need to answer some questions concerning the configuration of
|
||||
top itself.
|
||||
|
||||
The space command forces an immediate update. Sometimes, on loaded
|
||||
systems, this update will take a significant period of time (because all
|
||||
the output is buffered). So, if the short-term load average is above
|
||||
"LoadMax", then top will put the cursor home immediately after the space
|
||||
is pressed before the next update is attempted. This serves as a visual
|
||||
acknowledgement of the command. "LoadMax" should always be specified as a
|
||||
floating point number.
|
||||
|
||||
'EOF'
|
||||
./getans "LoadMax" number "$LoadMax" .$$
|
||||
set LoadMax = `cat .$$`
|
||||
|
||||
cat <<'EOF'
|
||||
|
||||
"Default TOPN" is the default number of processes to show. This is the
|
||||
number that will be used when the user does not specify the number of
|
||||
processes to show. If you want "all" (or infinity) as the default, use
|
||||
the value "-1".
|
||||
|
||||
'EOF'
|
||||
|
||||
./getans "Default TOPN" neginteger "$topn" .$$
|
||||
set topn = `cat .$$`
|
||||
|
||||
cat <<'EOF'
|
||||
|
||||
"Nominal_TOPN" is used as the default TOPN when Default_TOPN is Infinity
|
||||
and the output is a dumb terminal. If we didn't do this, then
|
||||
installations who use a default TOPN of Infinity will get every process in
|
||||
the system when running top on a dumb terminal (or redirected to a file).
|
||||
Note that Nominal_TOPN is a default: it can still be overridden on the
|
||||
command line, even with the value "infinity".
|
||||
|
||||
'EOF'
|
||||
|
||||
./getans "Nominal TOPN" integer "$NominalTopn" .$$
|
||||
set NominalTopn = `cat .$$`
|
||||
|
||||
cat <<'EOF'
|
||||
|
||||
Default Delay is the default number of seconds to wait between screen
|
||||
updates.
|
||||
|
||||
'EOF'
|
||||
|
||||
./getans "Default Delay" integer "$delay" .$$
|
||||
set delay = `cat .$$`

Version 3.5

Beta Release 11
|
||||
|

William LeFebvre
|
||||
with much help from others
|
||||
|
||||
|
||||
FREQUENTLY ASKED QUESTIONS AND THEIR ANSWERS
|
||||
|
||||
This FAQ is broken out in to several topics.
|
||||
|
||||
|
||||
GENERAL
|
||||
|
||||
1. "Where do I get the latest version of top?"
|
||||
|
||||
The official site for top is "ftp.groupsys.com" in the directory
|
||||
"/pub/top". It is also available from the following mirror sites:
|
||||
"pharos.dgim.doc.ca" in /packages/top, "uiarchive.uiuc.edu" in
|
||||
/pub/packages/top, "sunsite.auc.dk" in /pub/unix/top. European
|
||||
users should consider using the Denmark (dk) site.
|
||||
|
||||
2. "Is there a web page for top?"
|
||||
|
||||
Yes. Point your browser at http://www.groupsys.com/top. It includes
|
||||
all documentation, a nice interactive display which describes the
|
||||
various components of the output of top, web-based retrieval of the
|
||||
package, year 2000 information, and pointers to the mailing list.
|
||||
|
||||
3. "Is there a mailing list for top?"
|
||||
|
||||
The official list for announcements is "top-announce@groupsys.com".
|
||||
This list is managed by "majordomo@groupsys.com". Announcements of
|
||||
importance to all top users will be sent to this list, including new
|
||||
releases, availability of beta test versions, emergency revisions and
|
||||
patches, etc. Anyone is welcome to join top-announce. This is a
|
||||
read-only list. The list of subscribers will not (intentionally) be
|
||||
made available, and postings to the list are limited.
|
||||
|
||||
In addition, there is a top developers mailing list that is used by
|
||||
beta testers and other people who help me port the program to various
|
||||
machines. Membership to this list is solely at my discretion. If you
|
||||
feel qualified to act as a beta tester, or if you are doing development
|
||||
work on top (such as porting to a new platform), you may submit a
|
||||
request by sending a message to "top-spinners-request@groupsys.com"
|
||||
containing the word "subscribe". I will contact you within a few days,
|
||||
as my schedule permits.
|
||||
|
||||
4. "What about Year 2000 compliance"?
|
||||
|
||||
Top should not experience any problems with the transition to the year
|
||||
2000. A full statement concerning top and the year 2000 can be found
|
||||
in the file "Y2K" included with the distribution.
|
||||
|
||||
|
||||
5. "Why does it take so long for a new version of top to go through the
|
||||
beta test process?"
|
||||
|
||||
This is completely my fault. I have just not had the time to give top
|
||||
the attention it deserves. I thank everyone for their patience, and I
|
||||
hope that with the recent changes in the direction of my career that I
|
||||
can spend more time on this.
|
||||
|
||||
6. "Top is not written in ANSI C. Do you ever plan to change that?"
|
||||
|
||||
Top predates ANSI C by about 5 years. Yeah, it'll get "fixed" eventually.
|
||||
Probably in 3.6.
|
||||
|
||||
|
||||
CONFIGURING
|
||||
|
||||
7. "Configure said that it saw /proc and is recommending that I install top
|
||||
setuid root. Is there any way around this? Is it safe?"
|
||||
|
||||
There is no way around it. Complain to POSIX. Every effort has been made
|
||||
to make top a secure setuid program. However, we cannot guarantee that
|
||||
there are no security problems associated with this configuration. The
|
||||
places where top is most vulnerable are the builtin kill and renice
|
||||
commands. There is no internal top command that causes top to start a shell
|
||||
as a subprocess. Some SVR4 systems may contain a bug that enables a user to
|
||||
renice his own processes downward (to lower nice values that are more
|
||||
favorable for the process). This problem has been fixed for the Solaris 2.x
|
||||
modules, but may still exist in others. We will hopefully fix this up in
|
||||
the next release.
|
||||
|
||||
8. "Why is Configure a c-shell script? I thought c-shell scripts were
|
||||
evil?"
|
||||
|
||||
They are. :-) I'll probably be rewriting the Configure script for the
|
||||
next release, or switching to something like Gnu configure.
|
||||
|
||||
|
||||
COMPILING
|
||||
|
||||
9. "We just upgraded our operating system to a new version and top broke.
|
||||
What should we do?"
|
||||
|
||||
Recompile it. Top is very sensitive to changes in internal kernel data
|
||||
structures. It is not uncommon for a new version of the operating system to
|
||||
include changes to kernel data structures.
|
||||
|
||||
|
||||
RUNNING
|
||||
|
||||
10. "I just finished compiling top and it works fine for root, but when
|
||||
I try to run it as a regular user it either complains about files
|
||||
it can't open or it doesn't display all the information it should.
|
||||
Did I do something wrong?"
|
||||
|
||||
Well, you're just not done. On many operating systems today, access to
|
||||
many of the kernel memory devices and other system files is restricted to
|
||||
either root or a particular group. The Configure script figures this out
|
||||
(usually) and makes sure that the "intsall" rule in the Makefile will
|
||||
install top so that anyone can run it successfully. However, you have to
|
||||
*install* it first. Do this with the command "make install".
|
||||
|
||||
11. "Top is (not) displaying idle processes and I don't (do) want it to."
|
||||
|
||||
This default has only changed about a dozen times, and I finally got tired
|
||||
of people whining about it. Go read the manual page for the current version
|
||||
and pay special attention to the description of the "TOP" environment
|
||||
variable.
|
||||
|
||||
12. "We have so much memory in our machine that the memory status display
|
||||
(the fourth line) ends up being longer than 80 characters. This
|
||||
completely messes up top's output. Is there a patch?"
|
||||
|
||||
Most modules have been changed to use new memory formatting functions which
|
||||
will display large values in terms of megabytes instead of kilobytes. This
|
||||
should fix all occurences of this problem. If you encounter a system where
|
||||
this large memory display overflow is still occurring, please let me know
|
||||
(send mail to <wnl@groupsys.com>). Also note that newer versions of top can
|
||||
use columns beyond 79, and understand window resizes. So you can always
|
||||
make your window bigger.
|
||||
|
||||
13. "I tried to compile top with gcc and it doesn't work. I get
|
||||
compilation errors in the include files, or I get an executable that
|
||||
dumps core, or top displays incorrect numbers in some of the displays.
|
||||
What's wrong?"
|
||||
|
||||
Gnu CC likes very much to use its own include files. Not being a gcc
|
||||
expert, I can't explain why it does this. But I can tell you that if
|
||||
you upgrade your operating system (say from Solaris 2.4 to Solaris
|
||||
2.5) after installing gcc, then the include files that gcc uses will
|
||||
be incorrect, especially those found in the "sys" directory. Your
|
||||
choices are: (1) rebuild and reinstall the "standard" include files
|
||||
for gcc (look for scripts in the distribution called "fixincludes" and
|
||||
"fixinc.svr4"), (2) compile machine.c with "CFLAGS=-I/usr/include"
|
||||
then make the rest of the object files normally, or (3) use "cc".
|
||||
Solaris 2.6 users should also consult FAQ #20.
|
||||
|
||||
14. "The cpu state percentages are all wrong, indicating that my machine is
|
||||
using 95% system time when it is clearly idle. What's wrong?"
|
||||
|
||||
This can happen if you compiled with gcc using the wrong include files.
|
||||
See the previous question.
|
||||
|
||||
|
||||
SUNOS PROBLEMS
|
||||
|
||||
15. "I tried compiling top under SunOS version 4.1.x and it got compile time
|
||||
errors. Is there a patch?"
|
||||
|
||||
If you try compiling top in a "System V environment" under SunOS (that is,
|
||||
/usr/5bin is before /usr/bin on your path) then the compilation may fail.
|
||||
This is mostly due to the fact that top thinks its being compiled on a
|
||||
System V machine when it really isn't. The only solution is to put /usr/bin
|
||||
and /usr/ucb before /usr/5bin on your path and try again.
|
||||
|
||||
|
||||
SVR4-derived PROBLEMS
|
||||
|
||||
16. "When I run top on my SVR4-derived operating system, it displays all
|
||||
the system information at the top but does not display any process
|
||||
information (or only displayes process information for my own
|
||||
processes). Yet when I run it as root, everything works fine."
|
||||
|
||||
Your system probably uses the pseudo file system "/proc", which is by
|
||||
default only accessible by root. Top needs to be installed setuid root on
|
||||
such systems if it is going to function correctly for normal users.
|
||||
|
||||
|
||||
SOLARIS PROBLEMS
|
||||
|
||||
17. "Under Solaris 2, when I run top as root it only shows root processes,
|
||||
or it only shows processes with a PID less than 1000. It refuses to
|
||||
show anything else. What do I do?"
|
||||
|
||||
You probably compiled it with /usr/ucb/cc instead of the real C compiler.
|
||||
/usr/ucb/cc is a cc front end that compiles programs in BSD source-level
|
||||
compatability mode. You do not want that. Make sure that /usr/ucb is not
|
||||
on your path and try compiling top again.
|
||||
|
||||
18. "Under Solaris 2, I compiled top using what I am sure is the correct
|
||||
compiler but when I try to run it it complains about missing dynamic
|
||||
libraries. What is wrong?"
|
||||
|
||||
Check to see if you have LD_LIBRARY_PATH defined in your shell. If you do,
|
||||
make sure that /usr/ucblib is not on the path anywhere. Then try compiling
|
||||
top again.
|
||||
|
||||
19. "Under Solaris 2, when I try to run top it complains that it can't open
|
||||
the library "libucb.so.1". So I changed the LIBS line in m_sunos5.c
|
||||
to include -R/usr/ucblib to make sure that the dynamic linker will look
|
||||
there when top runs. I figured this was just an oversight. Was I
|
||||
right?"
|
||||
|
||||
No, you were not right. As distributed, top requires NO alterations
|
||||
for successful compilation and operations under any release of Solaris
|
||||
2. You probably compiled top with /usr/ucb/cc instead of the real C
|
||||
compiler. See FAQ #10 for more details.
|
||||
|
||||
20. "When I try to compile top under Solaris 2.6 using gcc I get compile
|
||||
time errors. There appear to be problems with the include files,
|
||||
such as 'u_rlimit has incomplete type' and/or 'u_saved_rlimit has
|
||||
incomplete type'. I've already run fixinc.svr4 as per FAQ #13.
|
||||
Why didn't that fix it?"
|
||||
|
||||
Only top versions 3.5 and later are compatible with Solaris 2.6. Make
|
||||
sure you are using the most up-to-date version. Earlier beta release
|
||||
copies of version 3.5 had additional problems when compiled with gcc.
|
||||
Retrieve the official version 3.5 (non-beta) release from one of the
|
||||
sites listed in FAQ #1 or FAQ #2.
|
||||
|
||||
|
||||
SCO PROBLEMS
|
||||
|
||||
21. "When I try to run Configure, it complains about a syntax error."
|
||||
|
||||
Some versions of SCO's csh do not understand the syntax "$<". Earlier
|
||||
releases of top depended on this syntax to read input from the installer's
|
||||
terminal during the installation process. Version 3.5 fixes this.
|
||||
|
||||
|
||||
SVR42 PROBLEMS
|
||||
|
||||
22. "The memory display doesn't work right. Why?"
|
||||
|
||||
This is a known bug with the svr42 module. The problem has been traced down
|
||||
to a potential bug in the "mem" driver. The author of the svr42 module is
|
||||
working on a fix.
|
||||
|
||||
|
||||
STILL STUCK
|
||||
|
||||
23. I'm still stuck. To whom do I report problems with top?"
|
||||
|
||||
The most common problems are caused by top's sensitivity to internal kernel
|
||||
data structures. So make sure that you are using the right include files,
|
||||
and make sure that you test out top on the same machine where you compiled
|
||||
it. Sun's BSD Source Compatability Mode is also a common culprit. Make
|
||||
sure you aren't using either /usr/ucb/cc or any of the libraries in
|
||||
/usr/ucblib. Finally, make sure you are using the correct module. If there
|
||||
does not appear to be one appropriate for your computer, then top probably
|
||||
will not work on your system.
|
||||
|
||||
If after reading all of this file and checking everything you can you are
|
||||
still stuck, then send mail to "wnl@groupsys.com". I will answer your mail
|
||||
when I have time. Please bear with me in that regard! If it looks like the
|
||||
problem is machine-specific, I will forward the report along to the module's
|
||||
author. If you would like to converse directly with the module author, the
|
||||
authors' names are listed at the beginning of the module .c file in the
|
||||
"machine" directory.

TOP
|
||||
Version 3.5
|
||||
|
||||
William LeFebvre
|
||||
and a cast of many
|
||||
|
||||
INSTALLATION
|
||||
|
||||
Configuration and installation of top is very straightforward. After
|
||||
unpacking the sources, run the script "Configure". It will present you
|
||||
with a series of questions, all of which should be explained in the
|
||||
presentation. After you have answered all the questions, "Configure" will
|
||||
perform all the necessary configuration. Once this is finished, type
|
||||
"make install". Make will compile the sources then install the resulting
|
||||
executable and manual page in the appropriate places.
|
||||
|
||||
The most difficult step in the configuration is the choice of an
|
||||
appropriate machine-specific module. The Configure script gives you a
|
||||
list of choices complete with brief descriptions of when each choice is
|
||||
appropriate. Each module is contained in a separate c file in the
|
||||
directory "machine". The module contains all of the machine-specific code
|
||||
that makes top work correctly on the architecture in question. All of the
|
||||
code in the top-level directory is machine-independent (or at least
|
||||
strives to be). Hints for some module choices that are not obvious are
|
||||
given at the end of this file.
|
||||
|
||||
The first comment in each c file in that directory contains the synopsis
|
||||
AND a detailed description of the machines for which that module is
|
||||
appropriate. It also contains a list of authors for that module. If you
|
||||
are really stumped in this choice, use grep to find your machine
|
||||
manufacturer's name or operating system name in machine/*.c. If you still
|
||||
can't find one that is appropriate, then chances are very good that one
|
||||
hasn't been written yet. If that is the case, then you are out of luck.
|
||||
|
||||
HANDLING MULTIPLE ARCHITECTURES
|
||||
|
||||
If you need to recompile top for a different architecture (that is, using
|
||||
a different module) you need to reconfigure top. A short cut is available
|
||||
to make this a little easier. If all of your previous answers to the
|
||||
configuration questions (except for the module name of course) are
|
||||
adequate for the new architecture, then you can just use the command
|
||||
"Configure <modulename>". The configuration script will reconfigure top
|
||||
using the new module and all the answers you gave last time. It will
|
||||
finish with a "make clean". Once that completes, type "make install"
|
||||
and make will compile the sources and do the installation.
|
||||
|
||||
HANDLING MULTIPLE OS VERSIONS
|
||||
|
||||
By far the most frequently received bug report for top is something like
|
||||
this: "We just upgraded our operating system to version 99.9.9.9 and top
|
||||
broke. What should we do?" The simple answer is "recompile".
|
||||
|
||||
Top is very sensitive to changes in internal kernel data structures
|
||||
(especially the proc and user structures). Some operating systems
|
||||
(especially SunOS) are notorious for changing these structure in every
|
||||
minor release of the OS. This means that a top executable made under one
|
||||
version of the OS will not always work correctly (if even at all) under
|
||||
another version. This is just one of those tough facts of life. There is
|
||||
really no way around it.
|
||||
|
||||
To make life even worse, some operating systems (SunOS again) will use
|
||||
slightly different proc and user structures on different models. For
|
||||
example, "top" built on a SparcStation 2 will not run correctly on a
|
||||
SparcStation 10, even if they are both running SunOS 4.1.3. These
|
||||
unfortunate circumstances make maintaining top very difficult, especially
|
||||
in an environment that runs several different versions of the same
|
||||
operating system.
|
||||
|
||||
But there is hope. If your operating system has a properly functioning
|
||||
"uname" command then you can handle this problem rather gracefully.
|
||||
Included in the distribution is a shell file called "metatop". All this
|
||||
shell file does is:
|
||||
|
||||
exec top-`uname -m`-`uname -r` "$@"
|
||||
|
||||
So when you run this script, it execs a filename that is unique to your
|
||||
specific machine architecture and your OS revision number.
|
||||
|
||||
To use "metatop", do the following:
|
||||
|
||||
. on any machine, run Configure and choose the module that is
|
||||
appropriate for the machine
|
||||
. for all machines which use the same module:
|
||||
. group machines according to machine architecture AND OS
|
||||
revision number (i.e.: sun4-4.1.1, sun4c-4.1.1, sun4c-4.1.2,
|
||||
sun4-4.1.3, sun4c-4.1.3, sun4m-4.1.3, ...)
|
||||
. for each group, choose one machine from that group and on it
|
||||
run "make clean; make installmeta".
|
||||
|
||||
|
||||
The "installmeta" rule in the makefile will insure that top is compiled,
|
||||
install the shell file "metatop" as "top", then install the executable
|
||||
"top" with a name appropriate to the machine architecture and OS revision.
|
||||
|
||||
|
||||
HINTS FOR CHOOSING THE CORRECT MODULE:
|
||||
|
||||
SOLARIS 2.x
|
||||
|
||||
All versions of Solaris will now work with the module sunos5. Version
|
||||
specific modules (such as sunos54) no longer exist.
|
||||
|
||||
|
||||
SUNOS 4.x AND MULTIPROCESSOR ARCHITECTURES
|
||||
|
||||
First, we need to be speaking the same language:
|
||||
|
||||
sun4 a regular sparc sun 4 architecture machine (sparc station 1,
|
||||
sparc station 2, IPC, SLC, etc.)
|
||||
|
||||
sun4m a multiprocessor sparc (Sparc 10, 4/670, 4/690)
|
||||
|
||||
I intended to write the sunos4 module so that an executable compiled on a
|
||||
sun4m machine would work correctly on a sun4 machine. Unfortunately my
|
||||
experiments indicate that this cannot be done. It turns out that the user
|
||||
structure is so different between these two architectures that nothing
|
||||
short of a serious hack will make the same executable work correctly on
|
||||
both machines. I recommend that you use the separate module "sunos4mp"
|
||||
when making an executable for a sun4m architecture, and use "sunos4" when
|
||||
making an executable for sun4 or sun4c architectures.
|
||||
|
||||
DIGITAL UNIX V4.0
|
||||
|
||||
This is the successor to DECOSF/1. Use the module decosf1.
|
||||
|
||||
SOLBOURNE OPERATING SYSTEM (OS/MP)
|
||||
|
||||
If you are running OS/MP version 4.1A, then use the module "osmp4.1a".
|
||||
|
||||
If you are running a version of OS/MP OLDER than 4.1A (that is, one
|
||||
of its predecessors), use the module "sunos4".
|
||||
|
||||
If you are running OS/MP 4.1B or LATER, use the module "sunos4mp".
|
||||
|
||||
HP/UX OPERATING SYSTEM
|
||||
|
||||
The module hpux8 works on all version 8 systems. Some say that it works
|
||||
with version 9 as well, but one user did send me a separate module for
|
||||
version 9. This module has only been tested on series 800 machines. I
|
||||
would recommend the following for those running version 9: try hpux9 and
|
||||
if it doesn't work then try hpux8. If neither work, then send mail to me
|
||||
and/or the modules' authors. Another note: we have a model 730 supposedly
|
||||
running version 9.01. The module hpux9 did not compile successfully, but
|
||||
the module hpux8 worked fine. The module hpux10 works on all revisions of
|
||||
HP/UX 10 except 10.10, where HP removed the definition of the proc structure
|
||||
from the system include files.
|
||||
|
||||
NET/2 386BSD SYSTEMS
|
||||
|
||||
If your version of the operating system has patchkit 2.4 installed,
|
||||
then you will need to modify machine/m_386bsd.c and uncomment the
|
||||
definition of PATCHED_KVM. This patchkit makes what more than a few
|
||||
people believe to be a wholly unnecessary patch to the way the kvm
|
||||
routines work.
|
||||
|
||||
A/UX SYSTEMS
|
||||
|
||||
There is a module for A/UX 3.0 and 3.1. Whether or not it works for
|
||||
any other version is not known. Proceed at your own risk.
|
||||
|
||||
Although AUX does not generally have a renice systemcall, it can be
|
||||
implemented by tweeking kernel memory. The flag IMPLEMENT_SETPRIORITY
|
||||
controls the inclusion of this code. It is off be default. While
|
||||
such a simple hack should not be difficult to get right, USE THIS
|
||||
FEATURE AT YOUR OWN RISK!

Instructions for porting top to other architectures.
|
||||
|
||||
This is still a preliminary document. Suggestions for improvement are
|
||||
most welcome.
|
||||
|
||||
My address is now "wnl@groupsys.com".
|
||||
|
||||
Before you embark on a port, please send me a mail message telling me
|
||||
what platform you are porting top to. There are three reasons for
|
||||
this: (1) I may already have a port, (2) module naming needs to be
|
||||
centralized, (3) I want to loosely track the various porting efforts.
|
||||
You do not need to wait for an "okay", but I do want to know that you
|
||||
are working on it. And of course, once it is finished, please send me
|
||||
the module files so that I can add them to the main distribution!
|
||||
|
||||
----------
|
||||
|
||||
There is one set of functions which extract all the information that
|
||||
top needs for display. These functions are collected in to one file.
|
||||
To make top work on a different architecture simply requires a
|
||||
different implementation of these functions. The functions for a
|
||||
given architecture "foo" are stored in a file called "m_foo.c". The
|
||||
Configure script looks for these files and lets the configurer choose
|
||||
one of them. This file is called a "module". The idea is that making
|
||||
top work on a different machine only requires one additional file and
|
||||
does not require changes to any existing files.
|
||||
|
||||
A module template is included in the distribution, called "m-template".
|
||||
To write your own module, it is a good idea to start with this template.
|
||||
If you architecture is similar to one for which a module already
|
||||
exists, then you can start with that module instead. If you do so,
|
||||
remember to change the "AUTHOR" section at the top!
|
||||
|
||||
The first comment in a module contains information which is extracted
|
||||
and used by Configure. This information is marked with words in all
|
||||
capitals (such as "SYNOPSIS:" and "LIBS:"). Go look at m-template: it
|
||||
is fairly self-explanatory. The text after "LIBS:" (on the same line)
|
||||
is extracted and included in the LIBS definition of the Makefile so
|
||||
that extra libraries which may be necessary on some machines (such as
|
||||
"-lkvm") can be specified in the module. The text after "CFLAGS:"
|
||||
(on the same line) is extracted and included as flags in the "CFLAGS"
|
||||
definition of the Makefile (thus in every compilation step). This is
|
||||
used for rare circumstances only: please don't abuse this hook.
|
||||
|
||||
Some operating systems have idiosyncrasies which will affect the form
|
||||
and/or content of the information top displays. You may wish to
|
||||
document such anomalies in the top man page. This can be done by adding
|
||||
a file called m_{modulename}.man (where {modulename} is replaced with
|
||||
the name of the module). Configure will automatically add this file to
|
||||
the end of the man page. See m_sunos4.man for an example.
|
||||
|
||||
A module is concerned with two structures:
|
||||
|
||||
The statics struct is filled in by machine_init. Each item is a
|
||||
pointer to a list of character pointers. The list is terminated
|
||||
with a null pointer.
|
||||
|
||||
struct statics
|
||||
{
|
||||
char **procstate_names; /* process state names */
|
||||
char **cpustate_names; /* cpu state names */
|
||||
char **memory_names; /* memory information names */
|
||||
};
|
||||
|
||||
The system_info struct is filled in by get_system_info and
|
||||
get_process_info.
|
||||
|
||||
struct system_info
|
||||
{
|
||||
int last_pid; /* last pid assigned (0 means non-sequential assignment) */
|
||||
double load_avg[NUM_AVERAGES]; /* see below */
|
||||
int p_total; /* total number of processes */
|
||||
int p_active; /* number of procs considered "active" */
|
||||
int *procstates; /* array of process state counters */
|
||||
int *cpustates; /* array of cpustate counters */
|
||||
int *memory; /* memory information */
|
||||
};
|
||||
|
||||
The last three pointers each point to an array of integers. The
|
||||
length of the array is determined by the length of the corresponding
|
||||
_names array in the statics structure. Furthermore, if an entry in a
|
||||
_names array is the empty string ("") then the corresponding value in
|
||||
the value array will be skipped over. The display routine displays,
|
||||
for example, the string procstate_names[0] then the number
|
||||
procstates[0], then procstate_names[1], procstates[1], etc. until
|
||||
procstate_names[N] == NULL. This allows for a tremendous amount of
|
||||
flexibility in labeling the displayed values.
|
||||
|
||||
"procstates" and "memory" are displayed as straight integer values.
|
||||
Values in "cpustates" are displayed as a percentage * 10. For
|
||||
example, the (integer) value 105 is displayed as 10.5%.
|
||||
|
||||
These routines must be defined by the machine dependent module.
|
||||
|
||||
int machine_init(struct statics *)
|
||||
|
||||
returns 0 on success and -1 on failure,
|
||||
prints error messages
|
||||
|
||||
char *format_header(char *)
|
||||
|
||||
Returns a string which should be used as the header for the
|
||||
process display area. The argument is a string used to label
|
||||
the username column (either "USERNAME" or "UID") and is always
|
||||
8 characters in length.
|
||||
|
||||
void get_system_info(struct system_info *)
|
||||
|
||||
caddr_t get_process_info(struct system_info *, int, int, int (*func)())
|
||||
|
||||
returns a handle to use with format_next_process
|
||||
|
||||
char *format_next_process(caddr_t, char *(*func)())
|
||||
|
||||
returns string which describes next process
|
||||
|
||||
int proc_compare(caddr_t, caddr_t)
|
||||
|
||||
qsort comparison function
|
||||
|
||||
uid_t proc_owner(pid_t)
|
||||
|
||||
Returns the uid owner of the process specified by the pid argument.
|
||||
This function is VERY IMPORTANT. If it fails to do its job, then
|
||||
top may pose a security risk.
|
||||
|
||||
|
||||
get_process_info is called immediately after get_system_info. In
|
||||
fact, the two functions could be rolled in to one. The reason they
|
||||
are not is mostly historical.
|
||||
|
||||
Top relies on the existence of a function called "setpriority" to
|
||||
change a process's priority. This exists as a kernel call on most 4.3
|
||||
BSD derived Unixes. If neither your operating system nor your C
|
||||
library supplies such a function, then you will need to add one to the
|
||||
module. It is defined as follows:
|
||||
|
||||
int setpriority (int dummy, int who, int niceval)
|
||||
|
||||
For the purposes of top, the first argument is meaningless.
|
||||
The second is the pid and the third is the new nice value.
|
||||
This function should behave just like a kernel call, setting
|
||||
errno and returning -1 in case of an error. This function MUST
|
||||
check to make sure that a non-root user does not specify a nice
|
||||
value less than the process's current value. If it detects such
|
||||
a condition, it should set errno to EACCES and return -1.
|
||||
Other possible ERRNO values: ESRCH when pid "who" does not exist,
|
||||
EPERM when the invoker is not root and not the same as the
|
||||
process owner.
|
||||
|
||||
Note that top checks process ownership and should never call setpriority
|
||||
when the invoker's uid is not root and not the same as the process's owner
|
||||
uid.
|
||||
|
||||
|
||||
The file "machine.h" contains definitions which are useful to modules
|
||||
and to top.c (such as the structure definitions). You SHOULD NOT need
|
||||
to change it when porting to a new platform.
|
||||
|
||||
Porting to a new platform should NOT require any changes to existing
|
||||
files. You should only need to add m_ files. If you feel you need a
|
||||
change in one of the existing files, please contact me so that we can
|
||||
discuss the details. I want to keep such changes as general as
|
||||
possible.

TOP
|
||||
Version 3.5
|
||||
|
||||
William LeFebvre
|
||||
and a cast of dozens
|
||||
|
||||
|
||||
If you do not want to read this entire file, then at least read
|
||||
the section at the end entitled "KNOWN PROBLEMS".
|
||||
|
||||
If you are having any problems getting top to work, please read the
|
||||
file "FAQ" *before* contacting me. Thank you.
|
||||
|
||||
"top" is a program that will give continual reports about the state of
|
||||
the system, including a list of the top cpu using processes. Version 3
|
||||
of "top" has three primary design goals: provide an accurate snapshot of
|
||||
the system and process state, not be one of the top processes itself, be
|
||||
as portable as possible.
|
||||
|
||||
Version 3 has many bug fixes from version 2.5, and it has also been
|
||||
reorganized in a major way to make it easy to port to other platforms.
|
||||
All system dependent code is now contained in one file.
|
||||
|
||||
Top now includes a configuration script called "Configure". It helps
|
||||
the installer choose the correct parameters for this particular
|
||||
installation. This script MUST be run before attempting to compile top.
|
||||
|
||||
Top requires read access to the memory files "/dev/kmem" and "/dev/mem"
|
||||
as well as the system image "/vmunix". Some installations have these
|
||||
files protected from general access. These sites would have to install
|
||||
this program in the same way that programs such as "ps" are installed.
|
||||
In addition, on those Unix variants that support the proc filesystem
|
||||
(such as SVR4 and Solaris 2), top requires read access to all the files
|
||||
in /proc: typically dictating that top be installed setuid to root.
|
||||
|
||||
CAVEAT: version 3 of top has internal commands that kill and renice
|
||||
processes. Although I have taken steps to insure that top makes
|
||||
appropriate checks with these commands, I cannot guarantee that these
|
||||
internal commands are totally secure. IF YOU INSTALL top as a SETUID
|
||||
program, you do so AT YOUR OWN RISK! I realize that some operating
|
||||
systems will require top to run setuid, and I will do everything I can
|
||||
to make sure that top is a secure setuid program.
|
||||
|
||||
Configure will ask you to input values for certain parameters. Before
|
||||
each parameter, Configure will display a description of what the
|
||||
parameter does. Read the description and choose an appropriate value.
|
||||
Sometimes a default will appear in brackets. Typing just return will
|
||||
choose the default.
|
||||
|
||||
System support now takes the form of "modules". Adding support for
|
||||
a different architecture requires only adding a module. Configure
|
||||
asks which module to use when it is configuring top. See the file
|
||||
"Porting" for a description of how to write your own module.
|
||||
|
||||
To compile and install "top", read the file "INSTALL" and follow the
|
||||
directions and advice contained therein.
|
||||
|
||||
Once you have created a binary for one particular type of machine, you
|
||||
can reconfigure for another type with "./Configure modulename" where
|
||||
"modulename" is replaced with the appropriate module name. All other
|
||||
parameter values are kept the same. Note that in some cases this may
|
||||
not be appropriate.
|
||||
|
||||
If you make any kind of change to "top" that you feel would be
|
||||
beneficial to others who use this program, or if you find and fix a bug,
|
||||
please send me the change.
|
||||
|
||||
Be sure to read the FAQ enclosed with the distrubution. It contains
|
||||
answers to the most commonly asked questions about the configuration,
|
||||
installation, and operation of top.

AVAILABILITY
|
||||
|
||||
The latest version of "top" is now being made available via anonymous
|
||||
FTP from the host "ftp.groupsys.com" in the directory "/pub/top".
|
||||
Additional modules will be made available in the directory
|
||||
"/pub/top/m". The site "eecs.nwu.edu" will continue to house copies
|
||||
of the distribution as well.

|
||||
KNOWN PROBLEMS:
|
||||
|
||||
Gnu CC
|
||||
|
||||
Compiling via Gnu CC continued to be the source of most of the
|
||||
questions I receive. By far the most common mistake made by those
|
||||
attempting to compile top with Gnu CC is out of date include files.
|
||||
When the operating system is upgraded, the include files that are part
|
||||
of the gcc package MUST also be updated. Gcc maintains its own
|
||||
include files. Even a minor OS upgrade can involve changes to some of
|
||||
the kernel's internal data structures, which are defined in include
|
||||
files in "sys". Top is very sensitive to these changes. If you are
|
||||
compiling with gcc and experience any sort of strange problems, please
|
||||
make sure the include files you are using are up to date BEFORE
|
||||
sending me a bug report. Look in the gcc source distribution for the
|
||||
shell script "fixincludes".
|
||||
|
||||
HP/UX 10.10
|
||||
|
||||
In their infinite wisdom, the folks at HP have decided that mere mortals
|
||||
such as you and I don't need to know what the kernel's proc structure looks
|
||||
like. To that end, they have removed all useful content from the include
|
||||
file <sys/proc.h> in version 10.10. As a result, top will not compile
|
||||
under 10.10. What HP is trying to accomplish with this move is to force
|
||||
iconoclasts such as myself to use "pstat" for collecting all process
|
||||
information. I have no immediate solution for this problem, but hope to
|
||||
obtain a sufficiently complete definition of "struct proc" at some point in
|
||||
the near future. Stay tuned.
|
||||
|
||||
DIGITAL UNIX 4.0 (DECOSF/1 V4.0)
|
||||
|
||||
A user has reported that idle processes are not displayed regardless
|
||||
of the flags used when invoking top. We have not had time to track
|
||||
this problem down.
|
||||
|
||||
DECOSF/1 V3.0
|
||||
|
||||
There is a bug either in the module, in utils.c, or in DEC's optimizer that
|
||||
is tickled by the decosf1 module when compiled under V3.0 (and perhaps
|
||||
earlier versions). Top compiled using DEC's compiler with optimization
|
||||
will consistently produce a segmentation fault (in format_next_process
|
||||
while calling sprintf). To work around this problem, either compile top
|
||||
with gcc or turn off optimization (compile without -O). We think that
|
||||
one of the bugs fixed in utils.c fixed this problem as well, but we are
|
||||
not certain.
|
||||
|
||||
|
||||
System V R 4.2
|
||||
|
||||
Load average and memory displays do not work. The problem has been
|
||||
traced down to a potential bug in the "mem" driver. The author
|
||||
of the svr42 module is working on a fix.

Top and the Year 2000
|
||||
|
||||
The software package top will not be affected by years numbering
|
||||
between 2000 and 2037. No portion of the top code stores dates on
|
||||
disk. All date processing in top is performed with functions from the
|
||||
Unix C library and Unix kernel. The specific functions are: time(2)
|
||||
and ctime(3S). These functions deal exclusively with conventional
|
||||
Unix time values (number of seconds since Midnight January 1, 1970
|
||||
GMT) and produce strings with a 4-digit year. At no point in the code
|
||||
for top are the last two digits used to represent a year.
|
||||
|
||||
Top and the Year 2038
|
||||
|
||||
In the year 2038 top will fail to represent the time of day correctly
|
||||
on 32-bit Unix operating systems. This is due to a limitation in the
|
||||
way Unix represents time. Top will only work on systems whose kernel
|
||||
call "time" and C library call "ctime" have been adjusted to represent
|
||||
time with a value greater than 32 bits. The exact date and time of
|
||||
this failure is 3:14:08 January 19, 2038 GMT. Note that this failure
|
||||
will only affect the display of the current time in the output from
|
||||
top.
|
||||
|
||||
|
||||
THERE IS ABSOLUTELY NO WARRANTY PROVIDED WITH THIS SOFTWARE.
|
||||
Please see the contents of the file "DISCLAIMER" for further
|
||||
information.

# Top is very sensitive to differences in the kernel, so much so that an
|
||||
# executable created on one sub-architecture may not work on others. It
|
||||
# is also quite common for a minor OS revision to require recompilation of
|
||||
# top. Both of these problems are especially prevalent on Suns. For
|
||||
# example, a top executable made under SunOS 4.1.1 will not run correctly
|
||||
# under SunOS 4.1.2, and vice versa. "metatop" attempts to solve this
|
||||
# problem by choosing one of several possible top executables to run then
|
||||
# executing it.
|
||||
#
|
||||
# To use metatop your operating system needs to have the command "uname"
|
||||
# as part of the standard OS release. MAKE SURE IT DOES before proceeding.
|
||||
# It will try to execute the command "top-`uname -m`-`uname -r`" For
|
||||
# example, on a sparcstation 1 running SunOS 4.1.1, it will try to run
|
||||
# "top-sun4c-4.1.1".
|
||||
#
|
||||
# INSTALLATION is easy. Just compile top as normal. Then use the command
|
||||
# "make metainstall" (on the same machine!) instead of the usual. "make"
|
||||
# will insure that this shell script is installed correctly then will install
|
||||
# the most recently made top executable with the correct name. Remember:

If standard output is an intelligent terminal (see below) then

|
||||
.PP
|
||||
.I Top
|
||||
makes a distinction between terminals that support advanced capabilities
|
||||
and those that do not. This
|
||||
distinction affects the choice of defaults for certain options. In the
|
||||
remainder of this document, an \*(lqintelligent\*(rq terminal is one that
|
||||
supports cursor addressing, clear screen, and clear to end of line.
|
||||
Conversely, a \*(lqdumb\*(rq terminal is one that does not support such
|
||||
features. If the output of
|
||||
.I top
|
||||
is redirected to a file, it acts as if it were being run on a dumb
|
||||
terminal.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-C
|
||||
Toggle CPU display mode.
|
||||
By default top displays the weighted CPU percentage in the WCPU column
|
||||
(this is the same value that
|
||||
.IR ps (1)
|
||||
displays as CPU).
|
||||
Each time
|
||||
.B \-C
|
||||
flag is passed it toggles between \*(lqraw cpu\*(rq mode
|
||||
and \*(lqweighted cpu\*(rq mode, showing the \*(lqCPU\*(rq or
|
||||
the \*(lqWCPU\*(rq column respectively.
|
||||
.TP
|
||||
.B \-S
|
||||
Show system processes in the display. Normally, system processes such as
|
||||
the pager and the swapper are not shown. This option makes them visible.
|
||||
.TP
|
||||
.B \-a
|
||||
Display command names derived from the argv[] vector, rather than real
|
||||
executable name. It's useful when you want to watch applications, that
|
||||
puts their status information there. If the real name differs from argv[0],
|
||||
it will be displayed in parenthesis.
|
||||
.TP
|
||||
.B \-b
|
||||
Use \*(lqbatch\*(rq mode. In this mode, all input from the terminal is
|
||||
ignored. Interrupt characters (such as ^C and ^\e) still have an effect.
|
||||
This is the default on a dumb terminal, or when the output is not a terminal.
|
||||
.TP
|
||||
.B \-H
|
||||
Display each thread for a multithreaded process individually.
|
||||
By default a single summary line is displayed for each process.
|
||||
.TP
|
||||
.B \-i
|
||||
Use \*(lqinteractive\*(rq mode. In this mode, any input is immediately
|
||||
read for processing. See the section on \*(lqInteractive Mode\*(rq
|
||||
for an explanation of
|
||||
which keys perform what functions. After the command is processed, the
|
||||
screen will immediately be updated, even if the command was not
|
||||
understood. This mode is the default when standard output is an
|
||||
intelligent terminal.
|
||||
.TP
|
||||
.B \-I
|
||||
Do not display idle processes.
|
||||
By default, top displays both active and idle processes.
|
||||
.TP
|
||||
.B \-j
|
||||
Display the
|
||||
.IR jail (8)
|
||||
ID.
|
||||
.TP
|
||||
.B \-t
|
||||
Do not display the
|
||||
.I top
|
||||
process.
|
||||
.TP
|
||||
.BI \-m display
|
||||
Display either 'cpu' or 'io' statistics. Default is 'cpu'.
|
||||
.TP
|
||||
.B \-n
|
||||
Use \*(lqnon-interactive\*(rq mode. This is identical to \*(lqbatch\*(rq
|
||||
mode.
|
||||
.TP
|
||||
.B \-P
|
||||
Display per-cpu CPU usage statistics.
|
||||
.TP
|
||||
.B \-q
|
||||
Renice
|
||||
.I top
|
||||
to -20 so that it will run faster. This can be used when the system is
|
||||
being very sluggish to improve the possibility of discovering the problem.
|
||||
This option can only be used by root.
|
||||
.TP
|
||||
.B \-u
|
||||
Do not take the time to map uid numbers to usernames. Normally,
|
||||
.I top
|
||||
will read as much of the file \*(lq/etc/passwd\*(rq as is necessary to map
|
||||
all the user id numbers it encounters into login names. This option
|
||||
disables all that, while possibly decreasing execution time. The uid
|
||||
numbers are displayed instead of the names.
|
||||
.TP
|
||||
.B \-v
|
||||
Write version number information to stderr then exit immediately.
|
||||
No other processing takes place when this option is used. To see current
|
||||
revision information while top is running, use the help command \*(lq?\*(rq.
|
||||
.TP
|
||||
.B \-w
|
||||
Display approximate swap usage for each process.
|
||||
.TP
|
||||
.B \-z
|
||||
Do not display the system idle process.
|
||||
.TP
|
||||
.BI \-d count
|
||||
Show only
|
||||
.I count
|
||||
displays, then exit. A display is considered to be one update of the
|
||||
screen. This option allows the user to select the number of displays he
|
||||
wants to see before
|
||||
.I top
|
||||
automatically exits. For intelligent terminals, no upper limit
|
||||
is set. The default is 1 for dumb terminals.
|
||||
.TP
|
||||
.BI \-s time
|
||||
Set the delay between screen updates to
|
||||
.I time
|
||||
seconds. The default delay between updates is \nD seconds.
|
||||
.TP
|
||||
.BI \-o field
|
||||
Sort the process display area on the specified field. The field name
|
||||
is the name of the column as seen in the output, but in lower case:
|
||||
\*(lqcpu\*(lq, \*(rqsize\*(lq, \*(rqres\*(lq, \*(rqtime\*(lq,
|
||||
\*(rqpri\*(lq, \*(rqthreads\*(lq, \*(lqtotal\*(lq, \*(rqread\*(lq,
|
||||
\*(rqwrite\*(lq, \*(rqfault\*(lq, \*(rqvcsw\*(lq, \*(rqivcsw\*(lq,
|
||||
\*(lqjid\*(lq, \*(rqswap\*(lq or \*(rqpid\*(lq.
|
||||
.TP
|
||||
.BI \-J jail
|
||||
Show only those processes owned by
|
||||
.IR jail .
|
||||
This may be either the
|
||||
.B jid
|
||||
or
|
||||
.B name
|
||||
of the jail.
|
||||
Use
|
||||
.B 0
|
||||
to limit to host processes.
|
||||
Using this option implies the
|
||||
.B \-j
|
||||
flag.
|
||||
.PP
|
||||
.BI \-U username
|
||||
Show only those processes owned by
|
||||
.IR username .
|
||||
This option currently only accepts usernames and will not understand
|
||||
uid numbers.
|
||||
.PP
|
||||
Both
|
||||
.I count
|
||||
and
|
||||
.I number
|
||||
fields can be specified as \*(lqinfinite\*(rq, indicating that they can
|
||||
stretch as far as possible. This is accomplished by using any proper
|
||||
prefix of the keywords
|
||||
\*(lqinfinity\*(rq,
|
||||
\*(lqmaximum\*(rq,
|
||||
or
|
||||
\*(lqall\*(rq.
|
||||
The default for
|
||||
.I count
|
||||
on an intelligent terminal is, in fact,
|
||||
.BI infinity .
|
||||
.PP
|
||||
The environment variable
|
||||
.B TOP
|
||||
is examined for options before the command line is scanned. This enables
|
||||
a user to set his or her own defaults. The number of processes to display
|
||||
can also be specified in the environment variable
|
||||
.BR TOP .
|
||||
The options
|
||||
.BR \-a ,
|
||||
.BR \-C ,
|
||||
.BR \-H ,
|
||||
.BR \-I ,
|
||||
.BR \-j ,
|
||||
.BR \-P ,
|
||||
.BR \-S ,
|
||||
.BR \-t ,
|
||||
.BR \-u ,
|
||||
.BR \-w ,
|
||||
and
|
||||
.B \-z
|
||||
are actually toggles. A second specification of any of these options
|
||||
will negate the first. Thus a user who has the environment variable
|
||||
.B TOP
|
||||
set to \*(lq\-I\*(rq may use the command \*(lqtop \-I\*(rq to see idle processes.
|
||||
.SH "INTERACTIVE MODE"
|
||||
When
|
||||
.I top
|
||||
is running in \*(lqinteractive mode\*(rq, it reads commands from the
|
||||
terminal and acts upon them accordingly. In this mode, the terminal is
|
||||
put in \*(lqCBREAK\*(rq, so that a character will be
|
||||
processed as soon as it is typed. Almost always, a key will be
|
||||
pressed when
|
||||
.I top
|
||||
is between displays; that is, while it is waiting for
|
||||
.I time
|
||||
seconds to elapse. If this is the case, the command will be
|
||||
processed and the display will be updated immediately thereafter
|
||||
(reflecting any changes that the command may have specified). This
|
||||
happens even if the command was incorrect. If a key is pressed while
|
||||
.I top
|
||||
is in the middle of updating the display, it will finish the update and
|
||||
then process the command. Some commands require additional information,
|
||||
and the user will be prompted accordingly. While typing this information
|
||||
in, the user's erase and kill keys (as set up by the command
|
||||
.IR stty )
|
||||
are recognized, and a newline terminates the input.
|
||||
.PP
|
||||
These commands are currently recognized (^L refers to control-L):
|
||||
.TP
|
||||
.B ^L
|
||||
Redraw the screen.
|
||||
.IP "\fBh\fP\ or\ \fB?\fP"
|
||||
Display a summary of the commands (help screen). Version information
|
||||
is included in this display.
|
||||
.TP
|
||||
.B q
|
||||
Quit
|
||||
.IR top.
|
||||
.TP
|
||||
.B d
|
||||
Change the number of displays to show (prompt for new number).
|
||||
Remember that the next display counts as one, so typing
|
||||
.B d1
|
||||
will make
|
||||
.I top
|
||||
show one final display and then immediately exit.
|
||||
.TP
|
||||
.B m
|
||||
Toggle the display between 'cpu' and 'io' modes.
|
||||
.TP
|
||||
.B n or #
|
||||
Change the number of processes to display (prompt for new number).
|
||||
.TP
|
||||
.B s
|
||||
Change the number of seconds to delay between displays
|
||||
(prompt for new number).
|
||||
.TP
|
||||
.B S
|
||||
Toggle the display of system processes.
|
||||
.TP
|
||||
.B a
|
||||
Toggle the display of process titles.
|
||||
.TP
|
||||
.B k
|
||||
Send a signal (\*(lqkill\*(rq by default) to a list of processes. This
|
||||
acts similarly to the command
|
||||
.IR kill (1)).
|
||||
.TP
|
||||
.B r
|
||||
Change the priority (the \*(lqnice\*(rq) of a list of processes.
|
||||
This acts similarly to the command
|
||||
.IR renice (8)).
|
||||
.TP
|
||||
.B u
|
||||
Display only processes owned by a specific set of usernames (prompt for
|
||||
username). If the username specified is simply \*(lq+\*(rq or \*(lq-\*(rq,
|
||||
then processes belonging to all users will be displayed. Usernames can be added
|
||||
to and removed from the set by prepending them with \*(lq+\*(rq and
|
||||
\*(lq-\*(rq, respectively.
|
||||
.TP
|
||||
.B o
|
||||
Change the order in which the display is sorted. This command is not
|
||||
available on all systems. The sort key names vary from system to system
|
||||
but usually include: \*(lqcpu\*(rq, \*(lqres\*(rq, \*(lqsize\*(rq,
|
||||
\*(lqtime\*(rq. The default is cpu.
|
||||
.TP
|
||||
.B e
|
||||
Display a list of system errors (if any) generated by the last
|
||||
.BR k ill
|
||||
or
|
||||
.BR r enice
|
||||
command.
|
||||
.TP
|
||||
.B H
|
||||
Toggle the display of threads.
|
||||
.TP
|
||||
.B i
|
||||
(or
|
||||
.BR I )
|
||||
Toggle the display of idle processes.
|
||||
.TP
|
||||
.B j
|
||||
Toggle the display of
|
||||
.IR jail (8)
|
||||
ID.
|
||||
.TP
|
||||
.B J
|
||||
Display only processes owned by a specific jail (prompt for jail).
|
||||
If the jail specified is simply \*(lq+\*(rq, then processes belonging
|
||||
to all jails and the host will be displayed.
|
||||
This will also enable the display of JID.
|
||||
.TP
|
||||
.B P
|
||||
Toggle the display of per-CPU statistics.
|
||||
.TP
|
||||
.B t
|
||||
Toggle the display of the
|
||||
.I top
|
||||
process.
|
||||
.TP
|
||||
.B w
|
||||
Toggle the display of swap usage.
|
||||
.TP
|
||||
.B z
|
||||
Toggle the display of the system idle process.
|
||||
.SH "THE DISPLAY"
|
||||
The actual display varies depending on the specific variant of Unix
|
||||
that the machine is running. This description may not exactly match
|
||||
what is seen by top running on this particular machine. Differences
|
||||
are listed at the end of this manual entry.
|
||||
.PP
|
||||
The top few lines of the display show general information
|
||||
about the state of the system, including
|
||||
the last process id assigned to a process (on most systems),
|
||||
the three load averages,
|
||||
the current time,
|
||||
the number of existing processes,
|
||||
the number of processes in each state
|
||||
(sleeping, running, starting, zombies, and stopped),
|
||||
and a percentage of time spent in each of the processor states
|
||||
(user, nice, system, and idle).
|
||||
It also includes information about physical and virtual memory allocation.
|
||||
.PP
|
||||
The remainder of the screen displays information about individual
|
||||
processes. This display is similar in spirit to
|
||||
.IR ps (1)
|
||||
but it is not exactly the same. PID is the process id,
|
||||
JID, when displayed, is the
|
||||
.IR jail (8)
|
||||
ID corresponding to the process,
|
||||
USERNAME is the name of the process's owner (if
|
||||
.B \-u
|
||||
is specified, a UID column will be substituted for USERNAME),
|
||||
PRI is the current priority of the process,
|
||||
NICE is the nice amount (in the range \-20 to 20),
|
||||
SIZE is the total size of the process (text, data, and stack),
|
||||
RES is the current amount of resident memory,
|
||||
SWAP is the approximate amount of swap, if enabled
|
||||
(SIZE, RES and SWAP are given in kilobytes),
|
||||
STATE is the current state (one of \*(lqSTART\*(rq, \*(lqRUN\*(rq
|
||||
(shown as \*(lqCPUn\*(rq on SMP systems), \*(lqSLEEP\*(rq, \*(lqSTOP\*(rq,
|
||||
\*(lqZOMB\*(rq, \*(lqWAIT\*(rq, \*(lqLOCK\*(rq or the event on which the
|
||||
process waits),
|
||||
C is the processor number on which the process is executing
|
||||
(visible only on SMP systems),
|
||||
TIME is the number of system and user cpu seconds that the process has used,
|
||||
WCPU, when displayed, is the weighted cpu percentage (this is the same
|
||||
value that
|
||||
.IR ps (1)
|
||||
displays as CPU),
|
||||
CPU is the raw percentage and is the field that is sorted to determine
|
||||
the order of the processes, and
|
||||
COMMAND is the name of the command that the process is currently running
|
||||
(if the process is swapped out, this column is marked \*(lq<swapped>\*(rq).
|
||||
.SH NOTES
|
||||
If a process is in the \*(lqSLEEP\*(rq or \*(lqLOCK\*(rq state,
|
||||
the state column will report the name of the event or lock on which the
|
||||
process is waiting.
|
||||
Lock names are prefixed with an asterisk \*(lq*\*(rq while sleep events
|
||||
are not.

|

Don't shoot me, but the default for
|
||||
.B \-I
|
||||
has changed once again. So many people were confused by the fact that
|
||||
.I top
|
||||
wasn't showing them all the processes that I have decided to make the
|
||||
default behavior show idle processes, just like it did in version 2.
|
||||
But to appease folks who can't stand that behavior, I have added the
|
||||
ability to set \*(lqdefault\*(rq options in the environment variable
|
||||
.B TOP
|
||||
(see the OPTIONS section). Those who want the behavior that version
|
||||
3.0 had need only set the environment variable
|
||||
.B TOP
|
||||
to \*(lq\-I\*(rq.
|
||||
.PP
|
||||
The command name for swapped processes should be tracked down, but this
|
||||
