With the rise of Kubernetes addressing power consumption in cloud is vital for capacity planning, environmental impact and detecting anomalies. Presenting Kepler, an observability framework for monitoring power within and beyond Kubernetes. Kepler works on various platforms and collects data via eBPF for minimal energy footprint. During the session, we will cover the following key points:

- Importance & challenges of power observability in the cloud.
- Kepler's methodologies;
- compiling data from performance counters
- approximation of power consumption using Machine Learning when direct monitoring isn't possible.
- Real-world adoption of Kepler for power monitoring.
- Live demo of power monitoring in Kubernetes via Kepler, Prometheus & Grafana.
- Kepler on Edge for power observability using OpenTelemetry for centralized dashboarding.
- A glimpse into our ongoing work on PEAKS, a power and energy-aware Kubernetes Scheduler developed using the Kepler Observability Framework.
