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 DisplayNFS 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 DisplayRPC 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:

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 availablewhen 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 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:

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 server.

badxid The number of times a reply from a server was received which did not correspond to any

outstanding call.

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
