.SH DESCRIPTION
|
||||
.I Pppstats
|
||||
reports certain kernel statistics kept about Point to Point
|
||||
Protocol traffic.
|
||||
.B pppstats
|
||||
prints PPP-related statistics.
|
||||
.PP
|
||||
The options are as follows:
|
||||
.TP
|
||||
\-i
|
||||
Repeat the display indefinitely every
|
||||
.I interval
|
||||
seconds.
|
||||
If no
|
||||
.I interval
|
||||
is specified, the default is 5 seconds.
|
||||
.TP
|
||||
\-v
|
||||
Verbose display of extra fields of information.
|
||||
.TP
|
||||
unit
|
||||
is a single digit specifying the slip interface. The default unit is
|
||||
.I 0
|
||||
for interface
|
||||
.I ppp0.
|
||||
.TP
|
||||
system
|
||||
Extract the name list from the specified system instead of the default, /kernel.
|
||||
.TP
|
||||
core
|
||||
Extract values associated with the name list from the specified
|
||||
core instead of the default, /dev/kmem.
|
||||
The
|
||||
.B -v
|
||||
flag causes
|
||||
.B pppstats
|
||||
to display additional statistics, such as the number of packets tossed
|
||||
(that is, which the VJ TCP header decompression code rejected).
|
||||
.PP
|
||||
By default,
|
||||
.I pppstats
|
||||
displays the following information:
|
||||
The
|
||||
.B -r
|
||||
flag causes
|
||||
.B pppstats
|
||||
to display the overall packet compression rate. The rate value is
|
||||
between 0 and 1, with 0 meaning that the data is incompressible.
|
||||
.PP
|
||||
.TP
|
||||
in
|
||||
bytes received
|
||||
.TP
|
||||
out
|
||||
bytes sent
|
||||
.TP
|
||||
pack
|
||||
packets received or sent
|
||||
.TP
|
||||
comp
|
||||
compressed packets received or sent
|
||||
.TP
|
||||
uncomp
|
||||
uncompressed packets received or sent
|
||||
.TP
|
||||
err
|
||||
input or output errors
|
||||
The
|
||||
.B -c
|
||||
flag is used to specify an alternate display mode that shows
|
||||
packet compression statistics: the number of packets and bytes
|
||||
uncompressed (that is, before compression or after decompression),
|
||||
compressed, and incompressible (packets which did not shrink on
|
||||
compression and were transmitted uncompressed), and the recent
|
||||
compression rate. This rate reflects the recent performance of the
|
||||
compression code rather than the overall rate achieved since
|
||||
compression was enabled.
|
||||
.PP
|
||||
With the \-v option, the following information is also displayed:
|
||||
.TP
|
||||
toss
|
||||
inbound packets tossed because of error
|
||||
.TP
|
||||
search
|
||||
searches for connection state
|
||||
.TP
|
||||
miss
|
||||
times we could not find a connectoin state
|
||||
.SH EXAMPLES
|
||||
The command ``pppstats -i 5'' will print what the system is doing every five
|
||||
seconds.
|
||||

The
|
||||
.B -i
|
||||
flag is used to specify the interval between printouts. The default is
|
||||
5 seconds.
|
||||
.PP
|
||||
<unit#> specifies which interface to use for gathering statistics.
