nfsstat - Network File System statistics
nfsstat [ -cmnrsz ]
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
That is, display everything, but reinitialize nothing.
-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.
-m Display statistics for each NFS mounted file system. This
includes the server name and address, mount flags, current read
and write sizes, the retransmission count, and the timers used
for dynamic retransmission. The srtt value contains the smoothed
round trip time, the dev value contains the estimated deviation,
and the cur value is the current backed-off retransmission value.
-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.
-s Display server 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
The server RPC display includes the following fields:
calls The total number of RPC calls received.
badcalls The total number of calls rejected by the RPC layer
(the sum of badlen and xdrcall as defined below).
nullrecv The number of times an RPC call was not available
when it was thought to be received.

badlen The number of RPC calls with a length shorter than a
minimum-sized RPC call.
xdrcall The number of RPC calls whose header could not be
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 The total number of RPC calls made.
badcalls The total number of calls rejected by the RPC layer.
retrans The number of times a call had to be retransmitted
due to a timeout while waiting for a reply from the
badxid The number of times a reply from a server was
received which did not correspond to any outstanding
timeout The number of times a call timed out while waiting
for a reply from the server.
wait The number of times a call had to wait because no
client handle was available.
newcred The number of times authentication information had
to be refreshed.
timers The number of times the calculated time-out value
was greater than or equal to the minimum specified
time-out value for a call.
The client NFS display shows the number of calls sent and rejected, 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
