Knative comes with Grafana pre-installed, which is an open source metric analytics and visualization tool. The Grafana pod is available in the knative-monitoring namespace and can be listed with the following command:

$ kubectl get pods -l app=grafana -n knative-monitoring

We can expose the Grafana UI with the kubectl port-forward command, which will forward local port 3000 to the port 3000 of the Grafana pod. Open a new terminal and execute the following command:
