-ofacility

Tag	Description
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

Tag	Description
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

Tag	Description
/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.

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/.
