With the upgrade of System Center Operations Manager to version 2012 the network monitoring has changed. The result is that the old 2007 management packs to monitor network devices still work, but no new devices can be discovered because the base class has been changed. So everyone who used management packs from the xSNMP suite before had to search for new solutions.
One of the management packs which were covered from the xSNMP suite was the xSNMP.APC.mp to monitor UPS/PDU devices from APC.
I have created a sample 2012 management pack for APC UPS and rPDU devices and published it here.
I have focused on using all already discovered information, so no discovery SNMP probes are necessary.
I added monitors for the following SNMP OIDs:
Additionally the following rules collect the current status (for UPS only) of:
The default interval for all rules and monitors is 10 minutes.
Please try it out and add comments for improvement.
