I've been writing a program to monitor various values dealing with SNMP --
it's not finished, but it works. Basically, you tell it what to watch,
and if the values go outside defined thresholds or certain values are/are
not met, it triggers an "alert" -- mail, paging (both TAP and SNPP), etc.
Right now, it's running under Linux with ucd-snmp, but porting it over to
FreeBSD should be simple -- the errors I'm getting are dumb ones that are
easily fixed. If anybody's interested, let me know -- it's not available
to the general public (I'm sorta embarresed by the code), but the geeks of
the world can get their hands on what I have so far by asking.....
