About Prometheus
Prometheus is a CNCF graduated project and the standard for cloud-native monitoring. It collects and stores metrics as time series data, identified by metric name and key-value label pairs.
The pull-based architecture scrapes metrics from instrumented targets at configured intervals. PromQL, its flexible query language, enables powerful data selection and aggregation for dashboarding and alerting.
Prometheus includes a built-in alert manager for handling notifications, service discovery for dynamic environments, and exporters for hundreds of third-party systems. It integrates seamlessly with Grafana for visualization.
As the backbone of Kubernetes monitoring, Prometheus is the most widely deployed monitoring system in cloud-native environments, with client libraries available for all major programming languages.
