Prometheus Architecture

Written Summary: Current Page

Key Takeaways

  • Prometheus Operator & CRDs – Manages Prometheus, Alertmanager, and related components in Kubernetes using custom resources (Prometheus, ServiceMonitor, PrometheusRule).
  • Metrics Collection – Node Exporter gathers system-level metrics; Kube State Metrics gathers Kubernetes object states; Prometheus scrapes them into its time-series DB.
  • Visualization – Grafana connects to Prometheus with PromQL to create dashboards for both system and application metrics.
  • Alerting – Prometheus evaluates PrometheusRule conditions and sends alerts to Alertmanager, which routes notifications to email, Slack, or PagerDuty.
