Monitoring for power outages on a dual-powered system

["James H. H. Lampert" <jamesl@xxxxxxxxxxxxxxxxx>]

We have one side of our production box plugged into the UPS, and the 
other side plugged into the wall. This not only guards against UPS 
malfunctions; it also gives us a way to monitor the power.

This weekend, we had an unattended 80-minute power outage, which (not 
surprisingly) drained the UPS completely dry, and left us down for most 
of a day.

The fact that I found a 110000AC SRC, and a CPPEA56 in the history log 
suggests that there's something I can tie into, so that the system can 
send a distress call as soon as the outage occurs.

But what should I be looking for?
