Prometheus Guides for Kube-Prometheus-Stack
Prometheus is the core time-series engine at the heart of kube-prometheus-stack, but the chart does not configure it directly — it uses the Prometheus Operator, which reads Kubernetes-native custom resources like ServiceMonitor, PodMonitor, and PrometheusRule to build Prometheus's scrape and alerting configuration automatically.
