Network UPS Tools 2.2.0

Network UPS Tools is a collection of programs which provide a common interface for monitoring and administering UPS hardware. Network UPS Tools uses a layered approach to connect all of the parts.
Drivers are provided for a wide assortment of equipment. They understand the specific language of each UPS and map it back to a compatibility layer.
This means both an expensive "smart" protocol UPS and a simple "power strip" model can be handled transparently.
This information is cached by the network server upsd, which then answers queries from the clients. upsd contains a number of access control features to limit the abilities of the clients. Only authorized hosts may monitor or control your UPS hardware if you wish.
Since the notion of monitoring over the network is built into the software, you can hang many systems off one large UPS and they will all shut down together.
Clients such as upsmon check on the status of the hardware and do things when necessary. The most important task is shutting down the operating system cleanly before the UPS runs out of power.
Other programs are also provided to log UPS status regularly, monitor status through your web browser, and more.
