In my experience, all modern operating systems and widely-used databases handle power interruption well. I can't recall an time where a filesystem or database was corrupted by power loss in decades. Adding a monitoring/shutdown system for basic UPSes is not worth the risk/hassle. I'd just monitor the power directly and let the system fall over when the UPS runs out of battery.
