upschk is a UPS monitor daemon for Advance-Intelligent UPSes such as X power Piconet and Micronet, Megatec, Falcon SG, etc. On power failure and restoration, it calls external scripts to perform a system shutdown. It supports power status logging in specified intervals via syslog. It works in both interactive and daemon modes.
