WinNUT

WinNUT is a port of the UPS mon client provided with the Network UPS Tools package. The idea behind this utility is to act as a background application or perhaps a service whose aim is to monitor a UPS as well as display the desired notifications and shut down the computer if necessary. The tool automatically detects the UPS port and can be installed as standalone as well as a service that starts automatically with Windows.

According to the developer, when the UPS goes critical, it would be wiser to make the windows client hibernate, rather than forcing a complete shut-off. Depending on other applications that may be running along with scheduled tasks or services, a full shut down can lead to data loss. The program was created in order to be able to add this option for your system or client.

The tool comes with a rugged interface consisting of a single window where you can specify the events that the app should log and hence, react to. These events include alerts, critical, error, warning, notice, info and debug. Depending on the apps and services running on your PC, the tool provides the option to shut down the computer normally or forced.
