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''
-

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.
