## Grafana
Grafana can be used to build dashboards and 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
```
