Kepler, re-architected: Improved power accuracy and a community call to action!
CNCF's Kepler project completed a major rewrite that eliminates its reliance on eBPF in favor of standard /proc and /sys access, improving accuracy in tracking power consumption for Kubernetes workloads while requiring significantly lower privileges for deployment. The changes reduced attribution gaps to nearly zero watts in testing and boosted code coverage to 90%, addressing previous issues with missing short-lived processes and inaccurate energy footprints that had created bottlenecks for power estimation models.
