Let's make every watt matter.

• Kepler (Kubernetes-based Efficient Power Level Exporter) is an open source Prometheus exporter that helps Kubernetes teams understand their workloads' power and energy use. It reads hardware energy data and attributes energy use to containers and pods. This gives teams workload-level visibility to help them make informed efficiency decisions.
• PEAKS (Power Efficiency Aware Kubernetes Scheduler) uses metrics exported by Kepler to help Kubernetes schedule to improve energy efficiency by placing Pods on optimal nodes.

Help improve Kepler through testing, documentation, code, or user feedback.

• We follow the CNCF Code of Conduct.
• Join our twice-monthly community meetings and #kepler-project on CNCF Slack to learn what we're working on today.
• Get started with Kepler: install Kepler and check your first energy metrics.
• Find a good first issue: and introduce yourself in the issue before starting work.
• Explore the project board: find other work you can help with.

• Read about the Kepler rewrite: what changed and why.
• Listen to the Kubernetes Podcast: Kepler explained and the challenges of measuring software energy use.
• Watch Kepler in action at CERN: see how researchers use energy dashboards to compare workloads and hardware.
