NAME
nfsstat - Network File System statistics
SYNOPSIS
nfsstat [-csnrz]
DESCRIPTION
nfsstat 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. If no options are
given the default is
nfsstat -csnr
That is, display everything, but reinitialize nothing.
Options
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 the
super-user only, and can be combined with any of the above options
to zero particular sets of statistics after printing them.
Displays
The server RPC display includes the fields:
calls total number of RPC calls received
badcalls total number of calls rejected
nullrecv number of times no RPC packet was available when trying
to receive
badlen number of packets that were too short
xdrcall number of packets that had a malformed header
The server NFS display shows the number of NFS calls received (calls) and
rejected (badcalls), and the counts and percentages for the various calls
that were made.
