NAME
nfsstat - list NFS statisticsSYNOPSIS
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, --mounts
- 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.
- -S, --since file
- Instead of printing current statistics, nfsstat imports statistics from file and displays the difference between those and the current statistics. Valid input files may be in the form of /proc/net/rpc/nfs (raw client stats), /proc/net/rpc/nfsd (raw server stats), or saved output from nfsstat itself (client and/or server stats). Any statistics missing from a saved nfsstat output file are treated as zeroes.
- -Z, --sleep
- Instead of printing current statistics and immediately exiting, nfsstat takes a snapshot of the current statistics and pauses until it receives SIGINT (typically from Ctrl-C), at which point it takes another snapshot and displays the difference between the two.
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 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 been 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.
