Observability with Prometheus and Grafana

Key Takeaways

When monitoring Kubernetes with Prometheus, keep these principles in mind:

• Service discovery is your foundation. Prometheus can automatically detect and scrape targets like pods, services, and nodes without manual configuration, thanks to Kubernetes service discovery.
• Each discovery role serves a purpose. Roles such as node, service, pod, endpoints, endpointslice, and ingress expose different metadata. Use these meta labels in kubernetes_sd_configs for precise relabeling and filtering.
