Honestly, PRTG has been rock solid and does everything. 2 hour, 1 day, 2 day, 30 day, 1 year graphing Alerting/alarms for unusual/down nodes (excess traffic, latency, interface errors) Mapping NTOP Group alerting/notification Custom Dashboards Report emailed automatically Sensor views by highest/lowest latency, bandwidth, etc

It has two power inputs. Connect input 1 to your battery backed power, and input 2 to a wall wart on an A/C outlet. Monitor the voltage on the two power inputs in your NMS. When input 2 has zero voltage, then the power is out. Add a current shunt for $20 more and then you can measure your load and voltage, from there you can estimate your expected run time. Probably not as easy as the APC management card. > I'm at my end.
