Custom Queries Insight Manager 7

[James Chapman]

We're having some heating/cooling problems in one of our Data Centers. I can pull out Temperature info for a single server, but does anyone know how to query a group of servers for their environmental data?

Thx.

James - temperature data is not a database item so it can't be queried on or reported on. However, if you have traps properly set so overtemp conditions are sent to Insight Manager 7, you should have no need to do this. Particularly, it would be impossible to get meaningful information about what's going on in the environment because the actual temp reading can be different from server to server model and even the different sensors inside a server.

For example, I just looked at a 2 processor DL360G3 that is running in a rack next to me. It has 3 sensors, 2 at the CPU and one near the main logic board. The current readings are 36C, 42C and 32C. That means I have as much as a 10 degree (almost 20%) delta among them, but what's the significance? Only by looking at the threshold values, 50C, 65C and 56C respectively do these values have any relevance. If you were to be able to pull back data from all the sensors on all your servers, it would be meaningless unless correlated this way.

By the way, in the same rack I have a DL380G3 which has 5 sensors with readings like the following:

Temp Threshold
CPU 36C 62C
CPU 36C 73C
IO Board 53C 68C
CPU 38C 73C
Pwr Supp 30C 55C

These are the caution thresholds; temperature can rise beyond this before it gets critical. The thresholds are set at values supplied based on ProLiant engineering measurements of what temps should be shown at what sensor location.

Not the answer I was hoping for, but from my initial investigation I kind of what I expected.

Thanks for the info.
