    # Monitor Calico Felix using Prometheus Operator

    Make sure you have these settings enabled in `felix`, in this case using enviornment variables:
    ```
    FELIX_PROMETHEUSMETRICSENABLED = True
    FELIX_PROMETHEUSMETRICSPORT = "9091"
    FELIX_PROMETHEUSGOMETRICSENABLED = True
    FELIX_PROMETHEUSPROCESSMETRICSENABLED = True
    ```

    Create a `Service` with `clusterIP` set to `None`, the service will be used to enumerate endpoints to scrape:
    ```
    apiVersion: v1
    kind: Service
    metadata:
    name: felix-metrics
    namespace: kube-system
    labels:
    k8s-app: calico-node
    spec:
    clusterIP: None
    ports:
    - port: 9091
    protocol: TCP
    name: metrics
    selector:
    k8s-app: calico-node
    ```

    Create a `ServiceMonitor` to start scrape the `calico-node` `Pods`:
    ```
    apiVersion: monitoring.coreos.com/v1
    kind: ServiceMonitor
    metadata:
    name: felix-metrics
    namespace: monitoring
    spec:
