Integrating Longhorn metrics into the Rancher monitoring system
Using Rancher, you can monitor the state and processes of your cluster nodes, Kubernetes components, and software deployments through integration with Prometheus, a leading open-source monitoring solution.
See here for the instruction about how to deploy/enable the Rancher monitoring system.
If you are using Rancher to manage your Kubernetes and already enabled Rancher monitoring, you can add Longhorn metrics to Rancher monitoring by simply deploying the following ServiceMonitor:
apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor metadata: name: longhorn-prometheus-servicemonitor namespace: longhorn-system labels: name: longhorn-prometheus-servicemonitor spec: selector: matchLabels: app: longhorn-manager namespaceSelector: matchNames: - longhorn-system endpoints: - port: manager
Once the ServiceMonitor is created, Rancher will automatically discover all Longhorn metrics.
You can then set up a Grafana dashboard for visualization.
You can import our prebuilt Longhorn example dashboard to have an idea.
You can also set up alerts in Rancher UI.
