41.Op Fl cemszW
42.Op Fl M Ar core
43.Op Fl N Ar system
44.Op Fl w Ar wait
45.Sh DESCRIPTION
46The
47.Nm
48command displays statistics kept about
49.Tn NFS
50client and server activity.
51For the NFSv4 server, the statistics are for operations within the Compound
52RPCs and not the count of RPCs.
53If you wish to compare RPC counts between NFSv3 and NFSv4, you must use
54statistics in the client(s).
55.Pp
56The options are as follows:
57.Bl -tag -width indent
58.It Fl c
59Only display client side statistics.
60.It Fl e
61Report the extra statistics collected by the NFS client and
62server for NFSv4.
63.It Fl M
64Extract values associated with the name list from the specified core
65instead of the default
66.Pa /dev/kmem .
67.It Fl m
68Report the mount options for all new NFS client mounts.
69This option overrides all others and
70.Nm
71will exit after completing the report.
72This option is only supported by the new NFS client.
73.It Fl N
74Extract the name list from the specified system instead of the default
75.Pa /boot/kernel/kernel .
76.It Fl s
77Only display server side statistics.
78.It Fl W
79Use wide format with interval short summary.
80This option is especially
81useful when combined with
82.Fl c
83or
84.Fl s
85and a time delay.
86.It Fl w
87Display a shorter summary of
88.Tn NFS
89activity for both the client and server at
90.Ar wait
91second intervals.
92.It Fl z
93Reset statistics after displaying them.
