NAME
nfsstat - Network File System statistics
SYNOPSIS
nfsstat [ -cmnrsz ]
DESCRIPTION
nfsstat displays statistical information about the NFS (Network File System) and
RPC (Remote Pro-
cedure Call), interfaces to the kernel. It can also be used to reinitialize this information. If no options are
given, the default is
nfsstat -cnrs
That is, display everything, but reinitialize nothing.
OPTIONS
-c Display client information. Only the client side
NFS and RPC information will be printed. Can be com-
bined 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 them.
DISPLAYS
The server RPC display includes the following fields:
badcalls The total number of calls rejected by the RPC layer (the sum of badlen and
xdrcall as defined below).
badlen The number of RPC calls with a length shorter than a minimum-sized
RPC call.
calls The total number of RPC calls received.
nullrecv The number of times an RPC call was not available when it was thought to be received.
xdrcall The number of RPC calls whose header could not be XDR decoded.
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:
badcalls The total number of calls rejected by the RPC layer.
badverfs The number of times the call failed due to a bad verifier in the response.
badxid The number of times a reply from a server was received which did not correspond to any
outstanding call.
calls The total number of RPC calls made.
cantconn The number of times the call failed due to a failure to make a connection to the server.
cantsend The number of times a client was unable to send an RPC request over a connectionless
transport when it tried to do so.
interrupts
The number of times the call was interrupted by a signal before completing.
newcred The number of times authentication information had to be refreshed.
nomem The number of times the call failed due to a failure to allocate memory.
