NAME
nfsstat - Network File System statistics
SYNOPSIS
nfsstat [-csnrz] [unix] [core]
DESCRIPTION
The nfsstat command displays statistical information about the
NFS (Network File System) and RPC (Remote Procedure Call),
interfaces to the kernel. It can also be used to reinitialize
this information.
Files
/stand/unix system namelist
/dev/kmem kernel memory
USAGE
If no options are given the default is
nfsstat -csnr
That is, display everything, but reinitialize nothing.
The options for nfsstat are as follows:
-c Display client information. Only the client side NFS
and RPC information will be printed. Can be combined
with the -n and -r options to print client NFS or client
RPC information only.
-s Display server information.
-n Display NFS information. NFS information for both the
client and server side will be printed. Can be combined
with the -c and -s options to print client or server NFS
information only.
-r Display RPC information.
-z Zero (reinitialize) statistics. This option is for use
by a privileged user only, and can be combined with any
of the above options to zero particular sets of
statistics after printing them.
unix Specifiy an alternate location for the UNIX kernel. The
default is /stand/unix.
