UPS

We can monitor two of our UPSs via SNMP #UPS:

Debian Setup

Install snmp and snmp-mibs-downloader (note: snmp-mibs-downloader is not available in stretch repository, so just download the deb from sid).

Download https://nagios.cscf.uwaterloo.ca/kiosk/powernet416.mib and place it in /usr/share/snmp/mibs

Getting Status

   snmpget -v 1 -c MSO mc-3015-h7-ups-1.cs.uwaterloo.ca PowerNet-MIB::upsBasicOutputStatus.0

This will return something like:

   PowerNet-MIB::upsBasicOutputStatus.0 = INTEGER: onLine(2)
