Network UPS Tools (NUT) is a suite of software component designed to monitor power devices, such as uninterruptible power supplies, power distribution units, solar controllers and servers power supply units. Many brands and models are supported and exposed via a network protocol and standardized interface.
History
Pavel Korensky's original apcd provided the inspiration for pursuing the APC Smart-UPS protocol in 1996. This is the same software that Apcupsd derived from, according to the Debian maintainer of the latter.
Russell Kroll, the original NUT author and coordinator, released the initial package, named smartupstools, in 1998. The design already provided for two daemons, upsd (which serves data) and upsmon (which protects systems), a set of drivers and examples, a number of CGI modules and client integration, and a set of client CLI tools (upsc, upsrw and upscmd), for interfacing the system with a specific UPS of a given model.
Arnaud Quette, the current project leader since 2004, has set up a team of programmers and a project infrastructure and opened NUT to a wider "power broker" approach.
