Several recent requests have been made on this list for information on
tools for logging, and analyzing NFS activities on NFS servers.
We use a tool developed by Dave Curry @ SRI called: nfswatch. It's
available from
unix.sri.com for anonymous ftp. It shows information in the following manner:

This is a handy tool when trying to analyze where the "hits" are coming
to/from.
It has a lot more information that can be gathered, depending on command line
flags that you use!!
