nfsstat − list NFS statistics
nfsstat [OPTION]...
The nfsstat displays statistics kept about NFS client and server activity.
-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.
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.
The Flags output from the -m option is the same as the flags give to the mount command.
/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.
rpc.nfsd(8). nfs(5).
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/.
