+## Monitoring
+
+We have included a few deployments to get some monitoring of your environment
+going as well. These include [Heapster](https://github.com/kubernetes/heapster),
+[InfluxDB](https://www.influxdata.com/time-series-platform/influxdb/), and
+[Grafana](https://grafana.com/).
+
+### Heapster
+
+In order to get cluster metrics into InfluxDB and Grafana we must first deploy
+Heapster. Heapster enables container monitoring and performance analysis for
+Kubernetes.
+To deploy Heapster simply run the following:
+
+```bash
+kubectl apply -f deployments/heapster.yaml
+...
+clusterrolebinding "heapster" created
+serviceaccount "heapster" created
+deployment "heapster" created
+service "heapster" created
+```
+
+### InfluxDB/Grafana
+
+After deploying [Heapster](#heapster) we are now ready to deploy InfluxDB and
+Grafana.
+
+> NOTE: The current deployment of InfluxDB/Grafana depends on [GlusterFS](#glusterfs)
+> being deployed. So if that has not been deployed yet you will either need to or
+> adjust the `influx-grafana.yaml` deployment to adjust for the volumes. Also
+> [Traefik](#deploying-traefik) for load balancing is required to properly connect
+> to Grafana's WebUI.
+
+```bash
+kubectl apply -f deployments/influx-grafana.yaml
+...
+deployment "monitoring-grafana" created
+service "monitoring-grafana" created
+deployment "monitoring-influxdb" created
+service "monitoring-influxdb" created
+ingress "monitoring-grafana" created
+```
+
+After the deployment above has been successful you should be able to connect to
+the Grafana WebUI at `http://wirelessIP/grafana`.

+
+And from the screenshot above you will notice that two dashboards
+(`cluster` and `pods`) are already pre-loaded during deployment.

 ## Resetting The Kubernetes Cluster
 
 If for any reason you would like to reset the Kubernetes cluster. You can easily
