Yep, I'd recommend having your event handler that fires on an overheat

At the very least, you'd need to get a look at how much Nagios itself is using, not just system-totals (check the manpage for interpreting results of free). Try 'top -n1 -p $nagiospid' or 'ps -F -p $nagiospid'. I've gone through several
Bringing up SNMP is a valid point (I'm currently handling ~25% of my active

To be fair, one situation where these wildcard template dependencies
don't work is when you want to define a number of dependent services
that rely on a service on the same host (i.e. not a number of separate
services on different hosts that rely on a single (or wildcardable)
