When I worked for BMC i was able to take the ProactiveNet components and use these metrics to monitor a very large vendors data center that was football fields in size. So what was don is that servers were grouped based on the floorspace grid they occupied. Then I created aggregate monitors for temperature, humidity, and power for each grid block. From this I could create even screens that showed the room and how it was performing. We could see the hot and cold zones of the floorspace. Also with the aggregate metrics we had dynamic thresholding in place to alert when a metric was 5% out of the daily, weekly, and monthly norm. What I would like to see is this aggregate monitoring put in place against each zone and the room as a whole. Then report back to us. Then maybe look into the weather chart code someone took from nagios and put in place within Zabbix. Maybe even later incorporate this functionality into the product. This example is great.

Perhaps an SNMP-aware thermometer? About the fans: perhaps they're set to always spin at the same RPM instead of temperature-controlled? I don't think that ~3500RPM is the max they can do. Apart from that: I flunked about every science course I had over the years, but how about this one: temperature starts rising, materials expand, bearings in the fans have more fricion, RPM lowers. Plausible? Busted? Myth confirmed? :) Ah that’s what happened….zabbix.com and zabbix.org down when trying to toy around with pre-2.0 thursday evening :)
