Keynote: Monitoring Kubernetes Clusters with Prometheus
summary
Prometheus is a pull-based system that stores raw multi‑dimensional metrics and scales to millions of time series; it scrapes histograms for on‑the‑fly percentiles, runs linear predictions to trigger alerts (example: linear prediction warns disk full in 4 hours), and discovers targets by watching the Kubernetes API so new pods are scraped immediately. Cluster setup uses node-exporter, kube‑state‑metrics, cAdvisor and etcd checks, and an operator plus ServiceMonitor CRDs produces a one-command deployment with alerts and Grafana dashboards.
