NFSSTAT(1)              FreeBSD General Commands Manual             NFSSTAT(1)

     nfsstat - display NFS statistics

     nfsstat [-cemoszW] [-M core] [-N system] [-w wait]

     The nfsstat command displays statistics kept about 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).

     The options are as follows:

     -c      Only display client side statistics.

     -e      Report the extra statistics collected by the new NFS client and
             server for NFSv4.  This option is incompatible with -o.

     -M      Extract values associated with the name list from the specified
             core instead of the default /dev/kmem.

     -m      Report the mount options for all new NFS client mounts.  This
             option overrides all others and nfsstat will exit after
             completing the report.  This option is only supported by the new
             NFS client.

     -N      Extract the name list from the specified system instead of the
             default /boot/kernel/kernel.

     -o      Report statistics for the old NFS client and/or server.  Without
             this option statistics for the new NFS client and/or server will
             be reported.

     -s      Only display server side statistics.

     -W      Use wide format with interval short summary.  This option is
             especially useful when combined with -c or -s and a time delay.

     -w      Display a shorter summary of NFS activity for both the client and
             server at wait second intervals.

     -z      Reset statistics after displaying them.

     /boot/kernel/kernel      default kernel namelist
     /dev/kmem                default memory file

     fstat(1), netstat(1), ps(1), systat(1), sysctl(3), iostat(8),
     nfsdumpstate(8), pstat(8), vmstat(8)

     The nfsstat command appeared in 4.4BSD.
