Dimensional data model

Prometheus models time series in a flexible dimensional data model. Time series are identified by a metric name and a set of key-value pairs.

Powerful queries

The PromQL query language allows you to query, correlate, and transform your time series data in powerful ways for visualizations, alerts, and more.

Precise alerting

Alerting rules are based on PromQL and make full use of the dimensional data model. A separate Alertmanager component handles notifications and silencing.

Simple operation

Prometheus servers operate independently and only rely on local storage. Developed in Go, the statically linked binaries are easy to deploy across various environments.

Instrumentation libraries

Prometheus provides a large number of official and community-contributed metrics instrumentation libraries that cover most major languages.

Ubiquitous integrations

Prometheus comes with hundreds of official and community-contributed integrations that allow you to easily extract metrics from existing systems.

Modern monitoring

## Monitoring for the cloud native world

Designed for the cloud native world, Prometheus integrates with Kubernetes and other cloud and container managers to continuously discover and monitor your services. It is the second project to graduate from the CNCF after Kubernetes.
