Private Cloud components expose metrics that can be scraped by Prometheus. This page will guide you how to monitor the Private Cloud components with Prometheus and Grafana community chart.

​
Provision the Pulsar cluster

Follow the Quick Start to install the sn-operator and provision the Pulsar cluster.
Make sure that use the same metadata.name for each component because this will be used for the label cloud_streamnative_io_cluster. For example, if you want to create a cluster called the pulsar-cluster, you should use the pulsar-cluster as the name for all components and specify at the metadata.name.

​
Install monitoring stacks

​
Add helm repo

  • Create a namespace for monitoring stacks
kubectl create ns monitor
  • Add prometheus and grafana helm repos
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

helm repo add grafana https://grafana.github.io/helm-charts

​

helm install grafana grafana/grafana -n monitor --set image.repository=streamnative/private-cloud-grafana --set image.tag=0.1.1
Fow detailed Grafana chart configurations, can refer the configuration.

​
Access the Grafana dashboards

  • Expose the Grafana service
kubectl expose svc grafana --name grafana-external -n monitor --port 3000 --target-port 3000 --type LoadBalancer
  • Get the Grafana password
kubectl get secret --namespace monitor grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
  • Access the Grafana
kubectl get svc -n monitor --field-selector metadata.name=grafana-external
