NAME
       nfsstat - list NFS statistics

SYNOPSIS
       nfsstat [OPTION]...

DESCRIPTION
       The nfsstat displays statistics kept about NFS client and server activ-
       ity.

OPTIONS
       -s, --server
	      Print only server-side statistics. The default is to print  both
	      server and client statistics.

       -c, --client
	      Print only client-side statistics.

       -n, --nfs
	      Print  only NFS statistics. The default is to print both NFS and
	      RPC information.

       -2     Print only NFS v2 statistics.  The  default  is  to  only	 print
	      information about the versions of NFS that have non-zero counts.

       -3     Print only NFS v3 statistics.  The  default  is  to  only	 print
	      information about the versions of NFS that have non-zero counts.

       -4     Print only NFS v4 statistics.  The  default  is  to  only	 print
	      information about the versions of NFS that have non-zero counts.

       -m, --mounted
	      Print information about each of the mounted NFS file systems.

	      If this option is used, all other options are ignored.

       -r, --rpc
	      Print only RPC statistics.

       -o facility
	      Display statistics for the specified facility, which must be one
	      of:

	      nfs    NFS protocol information, split up by RPC call.

	      rpc    General RPC information.

	      net    Network  layer statistics, such as the number of received
		     packets, number of TCP connections, etc.

	      fh     Usage information on  the	server's  file	handle	cache,
		     including	the total number of lookups, and the number of
		     hits and misses.

	      rc     Usage information on the server's	request	 reply	cache,
		     including	the total number of lookups, and the number of
		     hits and misses.

	      all    Display all of the above facilities.

       -v, --verbose
	      This is equivalent to -o all.

EXAMPLES
       nfsstat -o all -234
	      Show all information about all versions of NFS.

       nfsstat --verbose -234
	      Same as above.

       nfsstat -o all
	      Show all information about about active versions of NFS.

       nfsstat --nfs --server -3
	      Show statistics for NFS version 3 server.

       nfsstat -m
	      Show information about mounted NFS filesystems.

DISPLAY
       The Flags output from the -m option is the same as the  flags  give  to
       the mount command.

FILES
       /proc/net/rpc/nfsd
	      procfs-based interface to kernel NFS server statistics.

       /proc/net/rpc/nfs
	      procfs-based interface to kernel NFS client statistics.

       /proc/mounts
	      procfs-based interface to the mounted filesystems.

SEE ALSO
       rpc.nfsd(8).  nfs(5).

BUGS
       The  default  output has be changed.  To get the old default output you
       must run nfsstat --auto -2.

       The function of the -v and -a options have changed. The	-a  option  is
       now reserved for future use. The -v does what the -a option used to do,
       and the new -[234] options replace the -v option.

       The Display section should be more complete.

       Further bugs can be found or reported at http://nfs.sf.net/.
