side will be printed. Can be combined with the -c and -s
options to print client or server NFS information only.
Display RPC information.
Zero (reinitialize) statistics. This option is for use by a privileged
user only, and can be combined with any of the above options to zero
particular sets of statistics after printing them.

percentages for the various calls that were made.
total number of RPC calls received

The client RPC display includes the following fields:
The client NFS display shows the number of calls sent (``calls'')
and rejected (``badcalls''), 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 (nclsleep),
as well as a count of the various calls and their respective percentages.

total of calls rejected by a server
number of times a call had to be retransmitted
number of times a reply did not match the call
