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 project-team, a joint research group between the University of Lille and Inria.

The documentation of the project is available here.

Use Cases

PowerAPI is used in a variety of projects to address key challenges of GreenIT:

  • SmartWatts is a self-adaptive power meter that can estimate the energy consumption of software containers in real-time.
  • GenPack provides a container scheduling strategy to minimize the energy footprint of cloud infrastructures.
  • VirtualWatts 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.

Research Projects

Currently, PowerAPI is used in two research projects:
