'mon'.  It's used to monitor everything at Transmeta.  It's basically a
scheduler for running simple processes that return 0 for 'ok' or
non-zero for 'borked' (and text, if you want).  The scheduler calls
other simple programs for alerting and is configurable for things like
settings for days/times and dependencies (ie, if your switch pukes, you
don't want to be alerted for everything hanging off it).  It is packaged
in woody, and probably potato as 'mon'.

If you can hack perl (which is the easy way to write monitor scripts),
it's gangs of fun.  My favorite is one that I run that ensures OpenView
hasn't coredumped.  I love the irony. :)

I love mon.  It also has a very helpful mailing list.
