NAME

nfsstat - list NFS statistics

SYNOPSIS

nfsstat [OPTION]...

DESCRIPTION

The nfsstat displays statistics kept about NFS client and server activity.

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.

-4

Print only NFS v4 statistics.

-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.

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/.
