\uD83E\uDD14 Problem

No data is displayed in the Grafana “HiveMQ Cluster” Dashboard, after installing the hivemq-operator with monitoring.dedicated=true:

helm upgrade ${hivemqRelease} --install 'hivemq/hivemq-operator' \
  --namespace ${namespace} \
  --set monitoring.enabled=true \
  --set monitoring.dedicated=true \
  --set kube-prometheus-stack.prometheusOperator.admissionWebhooks.patch.image.repository=k8s.gcr.io/ingress-nginx/kube-webhook-certgen \
  --set kube-prometheus-stack.prometheusOperator.admissionWebhooks.patch.image.tag=v1.1.1
  ...

where:

• ${hivemqRelease} is your release name for the hivemq deployment;

• ${namespace} is the namespace you want to install the hivemq-operator.

...

1. Prepare a manifest definition for the Service Monitor, monitorService.yaml:

   Code Block
   apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor metadata: labels: hivemq-cluster: ${hivemqRelease} release: ${hivemqRelease} name: hivemq spec: endpoints: - port: metrics jobLabel: hivemq selector: matchLabels: hivemq-cluster: ${hivemqRelease} app: hivemq

   Do substitute ${hivemqRelease} with the actual name you gave to the hivemq-operator deployment.
   labels here do command the Prometheus to take the ServiceMonitor into account.
   selector here specifies which pods to scrape the data from.
   port here specifies the name of the port to which the metrics are exposed.

2. Apply the manifest

   Code Block
   kubectl apply -f monitorService.yaml --namespace ${namespace}

3. When all hivemq-pods are running and all their containers are ready, go to the Grafana and check if the data is updating in the “HiveMQ Cluster” dashboard.
