Prometheus
Also known as: Prometheus / プロメテウス
A CNCF open-source metrics collection and monitoring system. It scrapes metrics from targets using a pull model, supports PromQL queries and alert rules, and is the standard monitoring stack for Kubernetes when paired with Grafana.
Overview
Prometheus periodically scrapes metrics from HTTP endpoints. The Exporter mechanism converts metrics from diverse systems (Node Exporter, MySQL Exporter, etc.) into the Prometheus format.
Kubernetes Monitoring Standard
Combining kube-state-metrics with Prometheus enables fine-grained monitoring of Kubernetes cluster resource usage. The combined Grafana dashboard stack is the industry standard.
