What is Kepler?

Kepler (Kubernetes-based Efficient Power Level Exporter) uses eBPF to probe energy related system stats and exports as Prometheus metrics

It can help us get energy consumption metrics from a cluster.

Kepler requirements as outlined here:

  • Support for cgroup v2
  • Support for kernel-devel extensions
  • Provide the kernel headers (required by eBPF)
  • Kernel with eBPF support

For example, Kepler on Openshift has already been integrated and works. This integration can be used as an example of what configuration is needed, e.g.:

  kernelArguments:
    - systemd.unified_cgroup_hierarchy=1
    - cgroup_no_v1="all"
  extensions:
  - kernel-devel
