You can combine this option with the -c and -s options to display client or server NFS information only. -r Displays RPC information. Information for both the client and server sides is displayed. You can combine this option with the -c and -s options to display client or server NFS information only. -s Displays server information. Only server NFS and RPC information is displayed.

You can combine this option with one or more of the other options to reinitialize particular sets of statistics after displaying them.

DESCRIPTION nfsstat displays statistical information about the kernel's NFS and RPC interfaces. You can also use this option to reinitialize this information.
