nfsstat(1M)                                                        nfsstat(1M)


NAME
     nfsstat - display Network File System statistics

SYNOPSIS
     /usr/etc/nfsstat [ -csnrdz ]
     /usr/etc/nfsstat -C [ interval ]
     /usr/etc/nfsstat -m [ path ]

DESCRIPTION
     nfsstat displays statistical information about the Network File System
     (NFS) and Remote Procedure Call (RPC) interfaces to the kernel.  It can
     also be used to reinitialize this information.  If no options are given,
     the default is

          nfsstat -csnrd

     That is, print everything and reinitialize nothing.

OPTIONS
     -C [ interval ]
          Display using a "full-screen" form, which is updated periodically.
          The update period is specified by the  interval. Default interval is
          one second.  The values can be displayed as simple totals (r or
          "reset"), changes during the previous interval (d or "delta"), or
          changes since a fix moment (z or "zero").

     -c   Display client information.  Only the client side NFS and RPC
          information will be printed.  Can be combined with the -n and -r
          options to print client NFS or client RPC information only.

     -s   Display server information.  Works like the -c option above.

     -n   Display NFS information.  NFS information for both the client and
          server side will be printed.  Can be combined with the -c and -s
          options to print client or server NFS information only.

     -r   Display RPC information.  Works like the -n option above.

     -d   Display statistics about individual NFS daemons, including average
          call service times and utilisation.  Note that the utilisation
          statistics include both CPU time and time spent waiting for disk I/O
          to complete, and thus are a more accurate guide to NFS daemon usage
          than the CPU utilisation reported by ps.

     -z   Zero (reinitialize) statistics.  Can be combined with any of the
          above options to zero particular sets of statistics after printing
          them.  The user must have superuser privilege for this option to
          work.

     -m [ path ]
          Print information about mounted NFS filesystems. If path is
          specified only information about the filesystem which contains path


          is printed otherwise information about all NFS filesystem listed in
          /etc/mtab is printed.

          -m option overrides all other options specified on the command line.

FILES
     /unix         system namelist
     /dev/kmem     kernel memory
