HP SIM 5.1 Temperature readings

[Neil Whittaker]

I've been asked if I there is any way SIM can measure temperature readings for DL380 G4's(etc). Such as CPU temperature, ambient temp so that the readings can be viewed on demand or displayed graphically. I would be grateful for any advice.

Hi Neil,

You can get the above data from IPM (Insight Power Manager)which is an HP SIM add-on. Its a power monitoring and management application that provides centralized control of server power consumption and thermal output graphically. IPM is installed along with HP SIM. It is supported only the servers which has ILO2. You can go through below link for more info

ProLiant servers are self-managing. They will generate an alert at warning and critical temperature thresholds. Unlike systems that are non-ProLiant servers, the idea that one needs to see moment to moment the thermal readings is mistaken.

By design, HP SIM minimizes the amount of data it collects and the frequency so that it doesn't generate a lot of traffic on the network which can cause performance issues.

Insight Power Manager, an add-on to HP SIM, collects power consumption and heat generation statistics for supported ProLiant servers, but is not intended for monitoring thermal sensor readings.

The best source for ambient temperature readings is a building management system with sensors throughout the server room. "Intake air" on a server is invariably dirty air.

If you still think you must absolutely (and keep in mind that your boss has sent you on a fool's errand) collect thermal information, you can follow the instructions in the attached whitepaper using open source tools such as MRTG. However, keep in mind that the DL380G4 does not have an ambient sensor and that there are multiple internal sensors in a DL380 G4 and it is not enough to know the absolute value--it has context only in relation to the thresholds.

Thanks for the information, very useful.
