We have temperature probes that send snmp traps to Nagios to send messages when they get to a certain levels (warn, critical). We have one center of the server room probe that reports the ambient room temperature, the remaining probes are scattered through the server room behind the servers inside the racks. Based on the server to rack ratio, we have these set alerts set at different levels for each rack. The more servers in a rack the lower the warn level temp is, the fewer number of servers in a rack, the higher the temp warn levels are. In an HVAC event, we have a procedure of what to shut down to keep critical production servers up, but keep temps within acceptable ranges. All HP servers in our server room, and our shut down threshold is ~95 ambient room temp. We're also about 80% virtual guests, so a good number of our physical servers are actually virtual hosts. In a HVAC event, I could get to the point that I have half of my virtual hosts shut down if necessary.
