title: Heapster not pushing metrics to Stackdriver on Google container engine
body: <p>A newly created Kubernetes cluster on GKE is not pushing its metrics to Stackdriver. Output of <code>kubectl cluster-info</code> is:</p>
  
  <pre><code>Kubernetes master is running at https://XXX.XXX.XXX.XXX
  KubeDNS is running at https://XXX.XXX.XXX.XXX/api/v1/proxy/namespaces/kube-system/services/kube-dns
  KubeUI is running at https://XXX.XXX.XXX.XXX/api/v1/proxy/namespaces/kube-system/services/kube-ui
  Heapster is running at https://XXX.XXX.XXX.XXX/api/v1/proxy/namespaces/kube-system/services/monitoring-heapster
  </code></pre>
  
  <p>When I try to create a dashboard on Stackdriver with 'Custom Metrics', it says 'No Match Found'. Metrics were supposed to be present at this location with 'kubernetes.io' prefix according to Heapster documentation.</p>
  
  <p>I have also enabled Cloud Monitoring API with Read Write permission while creating cluster. Is it required for pushing cluster metrics? </p>
