.I Pppstats

reports certain kernel statistics kept about Point to Point

|
.PP
|
||||||
The options are as follows:
|
The
|

|
.B -v
|
||||||
\-i
|
flag causes
|
||||||
Repeat the display indefinitely every
|
.B pppstats
|
||||||
.I interval
|
to display additional statistics, such as the number of packets tossed
|
||||||
seconds.
|
(that is, which the VJ TCP header decompression code rejected).
|
||||||
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.
|
|
||||||
.PP
|
.PP
|
||||||
By default,
|
The
|
||||||
.I pppstats
|
.B -r
|
||||||
displays the following information:
|
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
|
.PP
|
||||||
.TP
|
The
|
||||||
in
|
.B -c
|
||||||
bytes received
|
flag is used to specify an alternate display mode that shows
|
||||||
.TP
|
packet compression statistics: the number of packets and bytes
|
||||||
out
|
uncompressed (that is, before compression or after decompression),
|
||||||
bytes sent
|
compressed, and incompressible (packets which did not shrink on
|
||||||
.TP
|
compression and were transmitted uncompressed), and the recent
|
||||||
pack
|
compression rate. This rate reflects the recent performance of the
|
||||||
packets received or sent
|
compression code rather than the overall rate achieved since
|
||||||
.TP
|
compression was enabled.
|
||||||
comp
|
|
||||||
compressed packets received or sent
|
|
||||||
.TP
|
|
||||||
uncomp
|
|
||||||
uncompressed packets received or sent
|
|

|
||||||
With the \-v option, the following information is also displayed:
|
The
|
||||||
.TP
|
.B -i
|
||||||
toss
|
flag is used to specify the interval between printouts. The default is
|
||||||
inbound packets tossed because of error
|
5 seconds.
|
||||||
.TP
|
.PP
|
||||||
search
|
<unit#> specifies which interface to use for gathering statistics.
|
||||||
searches for connection state
|

||||||
times we could not find a connectoin state
|
|

.SH EXAMPLES

seconds.
