Monitoring APC UPS via TheDude and SNMP

We have had some issues with our UPS systems recently and found that our monitoring and alerting systems were not working too well. After some tinkering I found that you can remotely monitor the UPS via The Dude. This method uses SNMP to monitor the UPS variables.

Examples of live UPS data including a UPS with a faulty battery.

Adding Probes for alerts:

Example of adding a specific probe.

I used the following Oid's:

iso.org.dod.internet.private.enterprises.318.1.1.1.2.2.1.0  - Battery % >= 90

iso.org.dod.internet.private.enterprises.318.1.1.1.7.2.3.0 - Battery Self Test != 0

iso.org.dod.internet.private.enterprises.318.1.1.1.2.2.2.0 - Battery Temp < 40

iso.org.dod.internet.private.enterprises.318.1.1.1.4.2.3.0 - Output Load < 90

iso.org.dod.internet.private.enterprises.318.1.1.1.2.2.4.0 - Replace Battery != 2

iso.org.dod.internet.private.enterprises.318.1.1.1.2.2.3.0 - Time Remaining > 10:00

You can use the code below to view the UPS status by adding it to the Label.
