This is a script for monitoring sensors (temperature, fans and voltage) and overall health of IBM servers. The script uses SNMPv1 to communicate with the Integrated Management Module (IMM).

The script was initially released by Ulric Eriksson. I have only made a few minor changes. Some of these changes were suggested by other users as comments on the Nagios Exchange for the original plugin by ulric.

I have tested the script with Op5 Monitor. It should work with other Nagios compatible products as well.

Tested with System X3550 M4 and System X3650 M3. Should work with other models as well.
