Set up and access Grafana

Set up Grafana in your cluster to import pre-built Grafana dashboards.

To access a pre-built Grafana dashboard, you must have Grafana installed in your cluster. You can easily do this by installing the Prometheus community Helm chart as shown in the steps on this page.

If you have an existing Grafana instance that runs in your cluster already, you can import any of the pre-built Grafana dashboards to your Grafana instance. To do that, simply skip this guide and follow the instructions to import the Cilium dashboard, operations dashboard, and OPA dashboard.

Install the Prometheus community Helm chart. This Helm chart automatically sets up Grafana in your cluster.

  helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update

helm upgrade --install kube-prometheus-stack \
prometheus-community/kube-prometheus-stack \
--version 30.0.1 \
--namespace monitoring \
--create-namespace \
--values - <<EOF
grafana:
  additionalDataSources:
  - name: prometheus-gloo-platform
    type: prometheus
    url: http://prometheus-server.gloo-mesh:80
EOF

Verify that the pods are all up and running.

  kubectl get pods -n monitoring

Set up port forwarding on your local machine to access the Grafana dashboard.

  kubectl port-forward $(kubectl get pods -n monitoring -o name | grep grafana) 8080:3000 -n monitoring

Open the Grafana dashboard in your web browser.
Log in to the Grafana dashboard with admin as the username, and prom-operator as the password. These are the default credentials that are set by the Prometheus community chart. You can change these credentials when you log in to Grafana.
