+## Grafana
+
+Grafana can be used to build dashboards and rich visualizations that use Prometheus as the datasource. Create the grafana deployment and service.
+
+```
+kubectl apply -f addons/grafana -R
+```
+
+Use `kubectl` to authenticate to the apiserver and create a local port-forward to the Grafana pod.
+
+```
+kubectl port-forward grafana-POD-ID 8080 -n monitoring
+```
+
+Visit [127.0.0.1:8080](http://127.0.0.1:8080), add the prometheus data-source (http://prometheus.monitoring.svc.cluster.local), and import your desired dashboard (e.g. 315).
