Running Prometheus & Grafana

Install Prometheus & Grafana

This is an example deployment that includes Prometheus and Grafana in a single deployment.

The default installation contains:

  • Grafana: A visualization dashboard with Cilium Dashboard pre-loaded.
  • Prometheus: a time series database and monitoring system.
$ kubectl apply -f
namespace/cilium-monitoring created
serviceaccount/prometheus-k8s created
configmap/grafana-config created
configmap/grafana-cilium-dashboard created
configmap/grafana-cilium-operator-dashboard created
configmap/grafana-hubble-dashboard created
configmap/prometheus created unchanged unchanged
service/grafana created
service/prometheus created
deployment.apps/grafana created
deployment.apps/prometheus created

This example deployment of Prometheus and Grafana will automatically scrape the Cilium and Hubble metrics. See the Monitoring & Metrics configuration guide on how to configure a custom Prometheus instance.

Deploy Cilium and Hubble with metrics enabled

Cilium, Hubble, and Cilium Operator do not expose metrics by default. Enabling metrics for these services will open ports 9090, 9091, and 6942 respectively on all nodes of your cluster where these components are running.

The metrics for Cilium, Hubble, and Cilium Operator can all be enabled independently of each other with the following Helm values:

  • global.prometheus.enabled=true: Enables metrics for cilium-agent.
  • global.operatorPrometheus.enabled=true: Enables metrics for cilium-operator.
  • global.hubble.metrics.enabled: Enables the provided list of Hubble metrics. For Hubble metrics to work, Hubble itself needs to be enabled with global.hubble.enabled=true. See Hubble exported metrics for the list of available Hubble metrics.

Refer to Monitoring & Metrics for more details about the individual metrics.


First, make sure you have Helm 3 installed.

If you have (or planning to have) Helm 2 charts (and Tiller) in the same cluster, there should be no issue as both version are mutually compatible in order to support gradual migration. Cilium chart is targeting Helm 3 (v3.0.3 and above).

Setup Helm repository:

helm repo add cilium

Deploy Cilium via Helm as follows to enable all metrics:

helm install cilium cilium/cilium --version 1.8.10 \
   --namespace kube-system \
   --set global.prometheus.enabled=true \
   --set global.operatorPrometheus.enabled=true \
   --set global.hubble.enabled=true \
   --set global.hubble.metrics.enabled="{dns,drop,tcp,flow,port-distribution,icmp,http}"


You can combine the above Helm options with any of the other installation guides.

How to access Grafana

Expose the port on your local machine

kubectl -n cilium-monitoring port-forward service/grafana 3000:3000

Access it via your browser: http://localhost:3000

How to access Prometheus

Expose the port on your local machine

kubectl -n cilium-monitoring port-forward service/prometheus 9090:9090

Access it via your browser: http://localhost:9090
