NAME

nfsstat - print NFS statistics

SYNOPSIS

/usr/sbin/nfsstat [-anrcsz] [-o facility] ...

DESCRIPTION

The nfsstat command retrieves and pretty-prints NFS kernel statistics. Currently, only server-side statistics are supported, because the NFS client does not yet collect any data.

OPTIONS

-s
Print only server-side statistics. The default is to print both server and client statistics.
-c
Print only client-side statistics. This is not currently supported.
-n
Print only NFS statistics. The default is to print both NFS and RPC information.
-r
Print only RPC statistics.
-z
Zero the kernel statistics counters. This option is not currently supported.
-o facility
Display statistics for the specified facility. The server statistics currently comprise the following facilities:
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.
