Key Takeaways
Kube-Prometheus Stack Deployment: Deploy production-ready monitoring using the kube-prometheus stack via Helm, which includes Prometheus, Grafana, Alertmanager, and essential Kubernetes monitoring components. This stack automatically configures service discovery, RBAC permissions, and persistent storage for your cluster.
Service Monitor Configuration: Use ServiceMonitor custom resources to automatically discover and scrape application metrics. Define label selectors, endpoint configurations, and scraping intervals to integrate your applications with the Prometheus ecosystem without manual configuration changes.
Kubernetes Resource Monitoring: Monitor cluster health with built-in kube-state-metrics and node-exporter components that expose pod status, resource utilization, and node metrics. These provide comprehensive visibility into cluster performance and resource allocation.
Application Integration: Integrate custom applications by exposing metrics endpoints and creating corresponding ServiceMonitor resources. The operator automatically updates Prometheus configuration, enabling seamless monitoring of new services as they're deployed to the cluster.
