              server and client statistics.

       -c     Print only client-side statistics.

       -n     Print  only NFS statistics. The default is to print both NFS and
              RPC information.

       -r     Print only RPC statistics.

       -o facility
              Display statistics for the specified facility, which must be one
              of:

              nfs    NFS protocol information, split up by RPC call.

              rpc    General RPC information.

              net    Network  layer statistics, such as the number of received
                     packets, number of TCP connections, etc.

              fh     Usage information on  the  server’s  file  handle  cache,
                     including  the total number of lookups, and the number of
                     hits and misses.

              rc     Usage information on the server’s  request  reply  cache,
