[🐛 Bug]: I can't set up receiving metrics from the router.

[DmiDvor]

What happened?

Hi. Since I haven't received a response here, I decided to create a new issue. I configured the monitoring block in values.yaml and metrics-exporter is up and running, but it doesn't show me any metrics from the router, only its own. I couldn't find any documentation on how to configure metrics from a Selenium 4 router. Please explain what I need to configure in metrics-exporter so it can receive metrics from the router. Do I need to pass the router's address? If so, how do I do this correctly? I tried passing the SE_GRAPH_URL inside the Metrix-Exporter pod

kubectl set env deployment/selenium-grid-selenium-metrics-exporter SE_GRAPHQL_URL=https://selenium-grid-selenium-router:4444/graphql

, but that didn't help.

There is nothing in the exporter logs except for a record that it has started and is listening on port 9199.

What am I doing wrong?

kube-prometheus-stack is disabled. I have an external Prometheus stack.

Here are the monitoring settings in values.yaml:

monitoring:
  enabledWithExistingAgent: true
  exporter:
    nameOverride: ""
    imageRegistry: "docker-proxy.host"
    imageName: "ricardbejarano/graphql_exporter"
    imageTag: "latest"
    # -- Custom pull secret for container in patch job
    imagePullSecret: ""
    port: 9199
    service:
      # -- Create a service for exporter
      enabled: true
      # -- Service type
      type: ClusterIP
      # -- Set specific clusterIP when serviceType is ClusterIP (see https://kubernetes.io/docs/concepts/services-networking/service/#type-clusterip)
      clusterIP: ""
      # -- Set specific externalName when serviceType is ExternalName (see https://kubernetes.io/docs/concepts/services-networking/service/#type-externalname)
      externalName: ""
      # -- Set specific loadBalancerIP when serviceType is LoadBalancer (see https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer)
      loadBalancerIP: ""
      # -- Node port for service
      nodePort: 30199
      # -- Set externalTrafficPolicy to Local or Cluster (see https://kubernetes.io/docs/concepts/services-networking/service-traffic-policy/)
      externalTrafficPolicy: ""
      # -- Set session affinity to None, ClientIP or ClientIPString
      sessionAffinity: ""
    replicas: 1
    # -- Tolerations for exporter pods
    tolerations: []
    envFrom:
      - configMapRef:
          name: selenium-grid-selenium-exporter-config
  additionalScrapeConfigs:
    key: ""
    value: ""
  annotations: 
    prometheus.io/scrape: "true"
    prometheus.io/port: "9199"
    prometheus.io/path: "/metrics"
