Prometheus is a completely open-source monitoring and alerting toolkit originally built at SoundCloud in 2012 and now a CNCF graduated project. It features a multi-dimensional data model, powerful PromQL query language, and pull-based architecture ideal for cloud-native and microservices environments. Prometheus can handle millions of time-series metrics with high reliability through independent servers. It includes built-in alerting via AlertManager and integrates seamlessly with Kubernetes. The system requires external tools like Grafana for advanced visualization but offers extensive third-party integrations.
