Prometheus is a free software application for event monitoring and alerting. It records metrics in a time series database built using an HTTP pull model, supporting high dimensionality through key-value label pairs, flexible queries, and real-time alerting. The project is written in Go and licensed under the Apache 2.0 License, with source code available on GitHub.

Prometheus originated at SoundCloud in 2012 and was accepted by the Cloud Native Computing Foundation (CNCF) in 2016, graduating from incubation in 2018. It is commonly paired with Grafana for dashboard visualization and supports a wide range of exporters and integrations.
