Getting off my topic, but we're using custom Nagios plugins for stuff that's
at levels that can't be read from SNMP - tests that need by their nature to
run locally and report back. Probably some way to do that in OpenNMS too?
Anyway, that being the standard Nagios way, it fits that need well.

I'm assuming the Cacti XML files to get multi-core graphs are SNMP ... if
that's right then standard Linux net-SNMP should allow that.

Yes. Is that a good 'good'?
