## What it is
Kepler (Kubernetes-based Efficient Power Level Exporter) is a Prometheus exporter that measures energy consumption at the container, pod, VM, and node level in Kubernetes clusters. It reads hardware sensors such as Intel RAPL and attributes power to workloads based on resource utilization, exposing metrics for Prometheus and Grafana.

## Use cases
- measure energy consumption of kubernetes pods and containers
- monitor cluster power usage with prometheus
- track carbon footprint of cloud-native workloads
- attribute power draw to individual containers based on CPU utilization
- build energy efficiency dashboards in grafana
- find energy-hungry workloads in a kubernetes cluster
- export node and pod power metrics for sustainability reporting

## When to choose
- you run Kubernetes and want per-pod or per-container energy metrics
- you already use Prometheus/Grafana and want to add power monitoring
- you need hardware-sensor-based (RAPL) power attribution on Linux nodes
- you want a CNCF sandbox project with Helm, operator, and OpenShift support

## When to avoid
- you need energy monitoring outside Kubernetes or on non-Linux platforms
- your hardware lacks RAPL or supported power sensors and you need precise measurements
- you want a standalone energy dashboard without a Prometheus stack
- you need a fully mature CNCF graduated project rather than a sandbox-stage one
