PowerAPI is a middleware toolkit for building software-defined power meters. Software-defined power meters are configurable software libraries that can estimate the power consumption of software in real-time. PowerAPI supports the acquisition of raw metrics from a wide diversity of sensors (eg., physical meters, processor interfaces, hardware counters, OS counters) and the delivery of power consumptions via different channels (including file system, network, web, graphical). As a middleware toolkit, PowerAPI offers the capability of assembling power meters «à la carte» to accommodate user requirements.
PowerAPI is an open-source project developed by the Spirals research group (University of Lille 1 and Inria) and fully managed with sbt.

We all stand on the shoulders of giants and get by with a little help from our friends. PowerAPI is written in Scala (version 2.11.4 under 3-clause BSD license) and built on top of:
- Akka (version 2.3.6 under Apache 2 license), for asynchronous processing
- Typesage Config (version 1.2.1 under Apache 2 license), for reading configuration files.
- Apache log4j2 (version 2.1 under Apache 2 license), for logging outside actors.
- powerspy.scala (version 1.0.1 under AGPL license), for using the PowerSpy powermeter.
- BridJ (version 0.6.2 under 3-clause BSD license), for system or C calls.
- perfmon2 (version 4.6.0 under MIT license), for accessing hardware performance counters.
- JFreeChart (version 1.0.19 under LGPL license), for creation of interactive and animated charts.
- Scala IO (version 0.4.3 under 3-clause BSD license), for an extensions of IO.
- Saddle (version 1.3.3 under Apache 2 license), for data manipulation.
