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.
 

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/.
