NAME

nfsstat − print NFS statistics

SYNOPSIS

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

-c

Print only client-side statistics.

-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, which must be one of:

nfs

NFS protocol information, split up by RPC call.

rpc

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.
