Install Grafana

View Metrics on the Grafana Dashboard​

To visualize metrics from various sources, you can import and configure Grafana dashboards.

Step 1: Install Grafana using Helm​

    helm repo add bitnami https://charts.bitnami.com/bitnami
    helm repo update bitnami
    helm install grafana bitnami/grafana -n grafana --create-namespace

Open the Grafana Dashboard​

Follow these steps to access and set up the Grafana dashboard:

Step 1: Decode the Grafana Admin Password​

kubectl get secret --namespace grafana grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

The login username is admin by default.

Step 2: Port-forward the Grafana Service​

kubectl port-forward svc/grafana -n grafana 8080:3000

Once port-forwarded, open http://localhost:8080 in your browser.

Step 3: Sign In and Add Prometheus as a Data Source​

  1. Go to Settings > Data Sources.

  2. Click Add data source.

Add Data Source

  1. Select Prometheus as the data source type.

Step 4: Configure Prometheus Connection​

To connect to Prometheus deployed in the same Kubernetes cluster, use kubeDNS to define the Prometheus service address. The format for an incluster prometheus setup is:

http://<prometheus-service-name>.<namespace>.svc.cluster.local:<port>

For example:

http://my-release-kube-prometheus-prometheus.default.svc.cluster.local:9090/
warning

Ensure the URL does not have trailing spaces or incorrect characters. Malformed URLs will cause the data source connection test to fail.

Step 5: Finalize Data Source Setup​

  • Set Prometheus type and Prometheus version as applicable.

  • Click Save & test. You should see a success message confirming the connection.
