prometheus/prometheus

Prometheus is a systems and service monitoring system developed by the Cloud Native Computing Foundation (CNCF). It collects metrics from configured targets at specified intervals, evaluates rule expressions, and displays the results. Prometheus stands out from other monitoring systems due to its multi-dimensional data model, powerful query language (PromQL), autonomous single server nodes, pull model for time series collection, and support for hierarchical and horizontal federation.

The project offers various ways to install Prometheus, including precompiled binaries, Docker images, and building from source. Precompiled binaries are available on prometheus.io, while Docker images can be found on Quay.io and Docker Hub. Building from source requires Go, NodeJS, and npm, and the Makefile provides several targets for building, testing, and formatting the code.

Prometheus supports multiple service discovery plugins and offers a React UI for visualizing and managing the collected data. The project also provides documentation, examples, and guides on its website.
