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

all Display all of the above facilities.
-v, --verbose
  This is equivalent to -o all.

EXAMPLES

TagDescription

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

DISPLAY

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

FILES

TagDescription
/proc/net/rpc/nfsd

/proc/net/rpc/nfs
  procfs-based interface to kernel NFS client statistics.
/proc/mounts
  procfs-based interface to the mounted filesystems.

SEE ALSO

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/.
