Plugin to check the temperature and humidity status via snmp of a APC Environmental module.
I created and added a Nagiosgrapher ncfg file, you can use this to get nice graphs and see the trends.
The APC environmental module I used: AP9312THI
BTW: I dont use the nagiosgrapher anymore. Started to use www.centreon.com which is in my opinion a great expansion of Nagios.
My two cents to the Nagios community :) maybe somebody will enjoy this plugin. I think they did cause today on the 27th of August 2009 it has been downloaded 1590 times from monitoringexchange.org
