nfsstat -- Network File System statistics

Syntax

nfsstat [ -cLlmnrsz ]

Description

The nfsstat command displays statistical information about the Network File System (NFS) and Remote Procedure Call (RPC) interfaces to the kernel. It can also be used to reinitialize this information. If no options are given, the default is:

nfsstat -csnr

That is, print client and server RPC and NFS information and reinitialize nothing.

Options


-c
display client information. Only the client-side NFS and RPC information will be printed. This option can be combined with the -n and -r options to print client NFS or client RPC information only.

-L
display Network Lock Manager information.

-l
display statistics about the directory name lookup cache. The directory name lookup cache attempts to reduce network and NFS server traffic by caching a directory/filename pair. Using the -l option will tell you about cache hits, misses, number of entries added to the cache and number of times the cache has been purged.

-m
display statistics for each NFS mounted filesystem. This includes server name and address, mount flags, current read and write sizes, the retransmission count, and the timers used for dynamic retransmission. The ``srtt'' value contains the smoothed round trip time, the ``dev'' value contains the estimated deviation, and the ``cur'' value is the current backed-off retransmission value.

-n
display NFS information. NFS information for both the client and server side will be printed. This option can be combined with the -c and -s options to print client or server NFS information only.

-r
display RPC information. This option works like the -n option above.

-s
display server information. This option works like the -c option above.

-z
zero (reinitialize) statistics. This option can be combined with any of the above options to zero particular sets of statistics after printing them. The user must have write permission on /dev/kmem for this option to work.
