# Accessing metrics
|
|
|
|
You access metrics through the [Grafana](https://grafana.com/) UI. Grafana is
|
|
the visualization tool for [Prometheus](https://prometheus.io/).
|
|
|
|
1. To open Grafana, enter the following command:
|
|
|
|
```
|
|
kubectl port-forward --namespace knative-monitoring $(kubectl get pods --namespace knative-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.
|
|
|
|
2. Navigate to the Grafana UI at [http://localhost:3000](http://localhost:3000).
|
|
|
|
3. 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
|
|
|
|
4. Set up an administrator account to modify or add dashboards by signing in
|
|
with username: `admin` and password: `admin`.
|
|
|
|
- Before you expose the Grafana UI outside the cluster, make sure to change the
|
|
password.
