I am attempting to write a little tool that would allow me to monitor
current systems via RPC calls and when certain thresholds are exceeded
actions are taken. I am looking for information on what is returned by the
"sunrpc stat $id" call. I have the output to diplay in window, but am having
trouble deciphering all the values, or what the threshold should be set at.
Can any point me to some info or examples? Thanks.

Threshholds will likely be system dependent. paging and swapping are very dependent on the function of the system in question. time shared systems may have a high degree of paging, or systems running very large memory intensive jobs (like finite element analysis). CPU systems will spend a lot of time in user. Web server may spend more time in system, and NFS servers may spend more time in I/O wait.
Whatever you do, it needs to be very configurable.
There are some old Sun Performance tuning white papers and books that discuss rstat. Newer books tend to focus on more fine grained metrics, and rstat is very coarse grained.
If you can find some old performance tuning papers for something like Solaris 2.2 you might find a good discussion there.
You might be able to find papers at Sun, or one of the public sun sites like opcom.sun.ca or sunsite.unc.edu
You might also look at perfmeter as it is displaying exactly the same information that you gather using sunrpc stat.
