|
||||
.Sh SYNOPSIS
|
||||
.Nm pstat
|
||||
.Op Fl Tfnstv
|
||||
.Op Fl M Ar core
|
||||
.Op Fl N Ar system
|
||||
.Sh DESCRIPTION
|
||||
.Nm Pstat
|
||||
displays open file entry, swap space utilization,
|
||||
terminal state, and vnode data structures.
|
||||
If
|
||||
.Ar corefile
|
||||
is given, the information is sought there, otherwise
|
||||
in
|
||||
.Pa /dev/kmem .
|
||||
The required namelist is taken from
|
||||
.Pa /vmunix
|
||||
unless
|
||||
.Ar system
|
||||
is specified.
|
||||
The
|
||||
.Fl n
|
||||
option specifies that devices should be printed out by major/minor
|
||||
number rather than by name.
|
||||
.Pp
|
||||
Options are
|
||||
.Bl -tag -width indent
|
||||
.It Fl T
|
||||
Prints the number of used and free slots in the several system tables
|
||||
and is useful for checking to see how large system tables have become
|
||||
if the system is under heavy load.
|
||||
.It Fl f
|
||||
Print the open file table with these headings:
|
||||
.Bl -tag -width indent
|
||||
.It LOC
|
||||
The core location of this table entry.
|
||||
.It TYPE
|
||||
The type of object the file table entry points to.
|
||||
.It FLG
|
||||
Miscellaneous state variables encoded thus:
|
||||
.Bl -tag -width indent
|
||||
.It R
|
||||
open for reading
|
||||
.It W
|
||||
open for writing
|
||||

|
||||
.It S
|
||||

|
||||
.It X
|
||||

|
||||
.It I
|
||||

|
||||
.El
|
||||
.It CNT
|
||||
Number of processes that know this open file.
|
||||
.It MSG
|
||||
Number of messages outstanding for this file.
|
||||
.It DATA
|
||||
The location of the vnode table entry or socket structure for this file.
|
||||
.It OFFSET
|
||||
The file offset (see
|
||||
.Xr lseek 2 ) .
|
||||
.El
|
||||
.It Fl s
|
||||
Print information about swap space usage on all the
|
||||
swap areas compiled into the kernel.
|
||||
The first column is the device name of the partition. The next column is
|
||||
the total space available in the partition. The
|
||||
.Ar Used
|
||||
column indicates the total blocks used so far; the
|
||||
.Ar Available
|
||||
column indicates how much space is remaining on each partition.
|
||||
The
|
||||
.Ar Capacity
|
||||
reports the percentage of space used.
|
||||
.Pp
|
||||
If more than one partition is configured into the system, totals for all
|
||||
of the statistics will be reported in the final line of the report.
|
||||
.It Fl t
|
||||
Print table for terminals
|
||||
with these headings:
