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.

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 a privileged user only, and can be combined with any of the above options to zero particular sets of statistics after printing them.

unix
Specify an alternate location for the UNIX kernel. The default is /stand/unix.

core
Specify an alternate location of the special file from where to read kernel memory. The default is /dev/kmem.

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.

The client RPC display includes the following fields:


``calls''
total number of RPC calls sent

``badcalls''
total of calls rejected by a server

``retrans''
number of times a call had to be retransmitted

``badxid''
number of times a reply did not match the call

``timeout''
number of times a call timed out

``wait''
number of times a call had to wait on a busy CLIENT handle

``newcred''
number of times authentication information had to be refreshed
The client NFS display shows the number of calls sent (``calls'') and rejected (``badcalls''), as well as the number of times a CLIENT handle was received (nclget), the number of times a call had to sleep while awaiting a handle (nclsleep), as well as a count of the various calls and their respective percentages.

Files


/stand/unix
system namelist

/dev/kmem
kernel memory

Usage

If no options are given, the default action is as if the command nfsstat -csnr had been entered. This displays everything but reinitializes nothing.

Notices

nfsstat displays separate statistics for NFSv2 and NFSv3 where appropriate.
