Observability: Prometheus, Grafana & AlertManager
Kubernetes observability is built from three tools: Prometheus collects metrics via pull-based scraping. Grafana reads from Prometheus to build dashboards. AlertManager receives alerts from Prometheus
Learning objectives
- Explain how Prometheus discovers scrape targets automatically in a dynamic Kubernetes environment, versus a static target list.
- Explain what Alertmanager adds on top of Prometheus's own alerting-rule evaluation.
- Design a basic set of Kubernetes-aware alerts covering both cluster health and application health.
