Network File System statistics
nfsstat [ -cLlmnrsz ]
The nfsstat command displays statistical
information about the Network File System (NFS) and
Remote Procedure Call (RPC) interfaces to the
kernel. It can also be used to reinitialize this
information. If no options are given, the default is:
That is, print client and server RPC and
NFS information and reinitialize nothing.
display client information. Only the client-side
NFS and RPC information will be

display statistics for each NFS mounted filesystem. This
includes 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.
display NFS information. NFS information for both the
