I've written custom monitor and action scripts for mon; it's pretty
straightforward beginner-level Perl.  If you like I can forward you
some of the stuff I've done.  Or, if you have specific questions I can
help with those.

IMHO mon has some pretty dang simple configuration.  I toyed with
Nagios but found it to be overkill if you don't need the visualization
stuff -- OTOH mon provided excellent 'pull switch if big red light
flashes, else push yellow button every three minutes' scripting.

Similarly with Cacti -- the abstraction provided is great unless
you're too small (or too diverse) to derive advantage from the economy
of scale.

Directly to your point, if you've got a specific task which you want
to accomplish under a detectible condition, mon should be really easy
to extend.
