  == Heapster
  
  https://github.com/kubernetes/heapster[Heapster] is a metrics aggregator and processor. It is installed as a cluster-wide pod. It gathers monitoring and events data for all containers on each node by talking to the Kubelet. Kubelet itself fetches this data from https://github.com/google/cadvisor[cAdvisor]. This data is persisted in a time series database https://github.com/influxdata/influxdb[InfluxDB] for storage. The data is then visualized using a using http://grafana.org/[Grafana] dashboard or can be viewed in Kubernetes Dashboard.
  
  Heapster collects and interprets various signals like compute resource usage, lifecycle events, etc, and exports cluster metrics via REST endpoints.
  
  Heapster, InfluxDB and Grafana are http://kubernetes.io/docs/admin/addons/[Kubernetes addons].
