Running 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
configmap/cilium-metrics-config created
namespace/cilium-monitoring created
configmap/prometheus created
deployment.extensions/prometheus created created created
serviceaccount/prometheus-k8s created
service/prometheus created
deployment.extensions/grafana created
service/grafana created
configmap/grafana-config created

Deploy Cilium with metrics enabled

Both cilium-agent and cilium-operator do not expose metrics by default. Enabling metrics for these services will open ports 9090 and 6942 on all nodes of your cluster where these components are running.

To deploy Cilium with metrics enabled, set the global.prometheus.enabled=true Helm value:

Download the Cilium release tarball and change to the kubernetes install directory:

curl -LO
tar xzvf v1.6.tar.gz
cd cilium-1.6/install/kubernetes

Install Helm to prepare generating the deployment artifacts based on the Helm templates.

Generate the required YAML file and deploy it:

helm template cilium \
   --namespace kube-system \
   --set global.prometheus.enabled=true \
   > cilium.yaml
kubectl create -f cilium.yaml


You can combine the global.prometheus.enabled=true option with any of the other installation guides.
