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.
About
PowerAPI is an open-source project developed by the Spirals research group (University of Lille 1 and Inria) and fully managed with setuptools.
The documentation is available here.

Use Cases
PowerAPI is used in a variety of projects to address key challenges of GreenIT:
- GenPack provides a Docker Swarm strategy to minimize the energy footprint of Docker containers deployed in a cluster
- BitWatts provides process-level power estimation of applications running in virtual machines
- Web Energy Archive ranks popular websites based on the energy footpring they imposes to browsers
- Greenspector optimises the power consumption of software by identifying potential energy leaks in the source code.
