Use the nfsstat command to display and reinitialize network
    file system (NFS) and remote procedure call (RPC) interface
    information for both client and server components. You can
    modify the display to include only NFS information, only RPC
    information, NFS version 2 or version 3, and only client or only
    server information. By default, nfsstat displays statistical
    information for client and server NFS versions 2 and 3, as well
    as client and server RPC information.

    If you have SYSUIC, SYSPRV, BYPASS, or OPER privileges, you can
    reinitialize the statistics for any or all of these components.
