# Accessing metrics
|
|
|
|
You access metrics through the [Grafana](https://grafana.com/) UI. Grafana is the visualization tool
|
|
for [Prometheus](https://prometheus.io/). To open Grafana, enter the following command:
|
|
|
|
```shell
|
|
kubectl port-forward -n monitoring $(kubectl get pods -n monitoring --selector=app=grafana --output=jsonpath="{.items..metadata.name}") 3000
|
|
```
|
|
|
|
This starts a local proxy of Grafana on port 3000. For security reasons, the Grafana UI is exposed only within
|
|
the cluster.
|
|
|
|
Navigate to the Grafana UI at [http://localhost:3000](http://localhost:3000).
|
|
Select the **Home** button on the top of the page to see the list of pre-installed dashboards (screenshot below):
|
|
|
|
|
|
The following dashboards are pre-installed with Knative Serving:
|
|
|
|
* **Revision HTTP Requests:** HTTP request count, latency, and size metrics per revision and per configuration
|
|
* **Nodes:** CPU, memory, network, and disk metrics at node level
|
|
* **Pods:** CPU, memory, and network metrics at pod level
|
|
* **Deployment:** CPU, memory, and network metrics aggregated at deployment level
|
|
* **Istio, Mixer and Pilot:** Detailed Istio mesh, Mixer, and Pilot metrics
|
|
* **Kubernetes:** Dashboards giving insights into cluster health, deployments, and capacity usage
|
|
|
|
To sign in as an administrator and modify or add dashboards, sign in with username `admin` and password `admin`.
|
|
Before you expose the Grafana UI outside the cluster, make sure to change the password.
