BitWatts is an extension of PowerAPI for building software-defined power meters inside virtualized environments. To have more details on what is a software-defined power meter, please consult: http://powerapi.org.
BitWatts is an open-source project developed by the Spirals research group (University of Lille 1 and Inria) in collaboration with the University of Neuchâtel.
The research leading to these results has received funding from the European Community’s Seventh Framework Programme [FP7/2007- 2013] under the ParaDIME Project, grant agreement no. 318693.
This project is fully managed with sbt.
The documentation is available here.

We all stand on the shoulders of giants and get by with a little help from our friends. BitWatts is written in Scala (version 2.11.4 under 3-clause BSD license) and built on top of:
- PowerAPI (version 3.2 under AGPL license), for using a software-defined power meter
- JUnixSocket (version 1.3 under Apache 2 license), for using unix domain sockets (quick time accesses)
- Apache Thrift (version 0.9.2 under Apache 2 license), for scalable cross-language services
- JeroMQ (version 0.3.4 under LGPL3 license), for using libzmq in native java.
- Apache log4j2 (version 2.3 under Apache 2 license), for logging.
