pppstats(8) and slstats(8) has been rewritten and merged
semantics and interface now follow the iostat/vmstat standard for statistics reporting. man page rewritten to match new semantics and interface. now shared.

.Sh DESCRIPTION
|
||||
.Pp
|
||||
The
|
||||
.B -v
|
||||
flag causes
|
||||
.B pppstats
|
||||
to display additional statistics, such as the number of packets tossed.
|
||||
.PP
|
||||
.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
|
||||
.B -i
|
||||
flag is used to specify the interval between printouts. The default is
|
||||
5 seconds.
|
||||
.PP
|
||||
.B pppstats
|
||||
must be installed set-group-id to kmem, or the user must have read
|
||||
access to /dev/kmem.
|
||||
.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
|
||||
.Ar wait
|
||||
interval is specified, the default is 5 seconds.
|
||||
.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 repeat
|
||||
.Ar count
|
||||
is specified, the default is infinity.
|
||||
.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 .
|
||||
.El
|
||||
.Pp
|
||||
The following fields are printed on the input side:
|

|
||||
The total number of bytes received by this interface.
|
