Practical Kubernetes Monitoring with Prometheus
summary
Deploys a ready-to-run monitoring platform using kube-prometheus stack (Prometheus, Alertmanager, Grafana, node-exporter, kube-state-metrics, cAdvisor) and shows how to add app metrics via the ServiceMonitor CRD. Claims a five-minute success to get dashboards and alerts, demonstrates a demo app with three replicas, two scraped, one unknown, and recommends in-cluster Prometheus, port-forward/ingress for UIs, jsonnet for custom rules/dashboards, remote_write to Thanos/Cortex, and moving from metrics to logs/traces (Loki/Tempo/OpenTelemetry).
