Today I ended up working out the details on what we want to monitor regarding our BladeCenter. The most interesting details (for us that is) are these:

  • Fan speeds for Chassis Cooling/Power Module Cooling Bay(s)
  • Temperature
  • Power Domain utilization

It wasn’t *that* hard to implement. Only trouble(s) I ran into, were (1) IBM did a real shitty job with the MIB’s. If you look closely into the mmblade.mib, you’re gonna notice, that not a single OID is specified for the events. (2) As the MIB’s weren’t documented anywhere, I had to look them up via snmpwalk (which I had never used before). So as a reminder (to myself), here’s how it is done:

snmpwalk -v1 -c public -O n 10.0.0.35 .1.3.6.1.4.1.2.3.51.2.2

This will get you a list, with a lot of output (5154 lines to be exact). Lucky me, the web interface of the management module/ssh interface is rather verbose, so all you need to do is compare those values with what you are looking for.

So for myself (and anyone interested) read ahead for the list of checks we are currently running on the management module.
