Monitoring ambient room temperature isn't fool proof. I'd be looking for a way to monitor the aircon kit itself. Most environmental monitoring systems have dry contact features as well as temp/humidity. Some high end aircon units have monitoring built in (eg APC FM40). You could probably build an air flow dry contact type of trigger... or have some relays installed in your air con tied to the fans and/or compressors. Or you chould just measure the air temp just inside your air con ducts. That temperature drop on a failure is more sudden than ambient room temp changes.
Knowing the roof temp in your data centre has gone up 5 degrees is all good and well, but the start of the problem might have started 5..10..15 minutes ago. That's time you can't get back to address the real issue. :) _______________________________________________ Nagios-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
