.Sh DESCRIPTION
|
|
.Pp
|
|
The
|
|
.Nm pppstats
|
|
utility reports PPP-related statistics for the specified PPP
|
|
.Ar interface .
|
|
If the
|
|
.Ar interface
|
|
is unspecified, it will default to ppp0.
|
|
.Pp
|
|
The
|
|
.Nm slstats
|
|
utility reports SLIP-related statistics for the specified SLIP
|
|
.Ar interface .
|
|
If the
|
|
.Ar interface
|
|
is unspecified, it will default to sl0.
|
|
.Pp
|
|
Otherwise
|
|
.Nm pppstats
|
|
and
|
|
.Nm slstats
|
|
function identically. Both programs will report interface-specific
|
|
statistics at regular intervals. The display is split horizontally
|
|
into input and output sections containing columns of statistics
|
|
describing the properties and volume of packets received and
|
|
transmitted by the interface.
|
|
.Pp
|
|
The first report will consist of a snapshot of the interface's
|
|
statistics. Further output, if any, will describe activity between
|
|
report intervals.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl c Ar count
|
|
Repeat the display
|
|
.Ar count
|
|
times. The first display is for the time since a reboot and each
|
|
subsequent report is for the time period since the last display. If no
|
|
repeat
|
|
.Ar count
|
|
is specified, the default is infinity.
|
|
.It Fl v
|
|
Display additional statistics demonstrating the efficacy of VJ header
|
|
compression and providing more explicit information on failure
|
|
distribution.
|
|
.It Fl w Ar wait
|
|
Pause
|
|
.Ar wait
|
|
seconds between each display. If no
|
|
.Ar wait
|
|
interval is specified, the default is 5 seconds.
|
|
.It Fl M Ar core
|
|
Extract values associated with the name list from the specified core
|
|
instead of the default
|
|
.Pa /dev/kmem .
|
|
.It Fl N Ar system
|
|
Extract the name list from the specified system instead of the default
|
|
.Pa /netbsd .
