Heapster

Heapster enables Container Cluster Monitoring and Performance Analysis. It collects and interprets various signals like compute resource usage, lifecycle events, etc, and exports cluster metrics via REST endpoints. The Chart can also enable eventer, which can send the kubernetes event logs to a remote location.

QuickStart

$ helm install stable/heapster

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/heapster

Uninstalling the Chart
