.Sh NAME
.Nm nfsstat
.Nd display
.Tn NFS
statistics
.Sh SYNOPSIS
.Nm
.Op Fl cemszW
.Op Fl M Ar core
.Op Fl N Ar system
.Op Fl w Ar wait
.Sh DESCRIPTION
The
.Nm
command displays statistics kept about
.Tn NFS
client and server activity.
For the NFSv4 server, the statistics are for operations within the Compound
RPCs and not the count of RPCs.
If you wish to compare RPC counts between NFSv3 and NFSv4, you must use
statistics in the client(s).
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl c
Only display client side statistics.
.It Fl e
Report the extra statistics collected by the NFS client and
server for NFSv4.
.It Fl M
Extract values associated with the name list from the specified core
instead of the default
.Pa /dev/kmem .
.It Fl m
Report the mount options for all new NFS client mounts.
This option overrides all others and
.Nm
will exit after completing the report.
This option is only supported by the new NFS client.
.It Fl N
Extract the name list from the specified system instead of the default
.Pa /boot/kernel/kernel .
.It Fl s
Only display server side statistics.
.It Fl W
Use wide format with interval short summary.
This option is especially
useful when combined with
.Fl c
or
.Fl s
and a time delay.
.It Fl w
Display a shorter summary of
.Tn NFS
activity for both the client and server at
.Ar wait
second intervals.
.It Fl z
Reset statistics after displaying them.
