I'm trying to setup monitoring and alerting for a handful of APC smart UPS devices.
Ideally, what I'd like is the node to track things like whether or not it's on battery, how much runtime is remaining, and a couple of other minor items.
I'd also really like to have it trigger an alert when the UPS starts running on battery and when the remaining runtime drops below a certain amount.
It doesn't look like there is much pre-built for this which considering the popularity of APC UPSs kind of baffles me. I've seen a few custom Universal Device Pollers which look at one specific value, but I'm not seeing how to incorporate that information into the node status or how to trigger alerts from it.
