Prometheus is a complete monitoring and trending system with built-in and active scraping, storing, querying, graphing and alerting based on time series data.
Prometheus is an open-source toolkit initially built at SoundCloud for monitoring and alerting. The toolkit is now a standalone open source project and maintained independently of any company.
The toolkit collects metrics from monitored targets by scrapping HTTP endpoints on those targets. Most Prometheus components are in Go. Some written in Java, Python, and Ruby.
Prometheus works well to record any numerical time series. It fits both machine-centric monitoring and high-dynamic service-oriented architecture monitoring. In addition to making it easier to run and integrate into your environment, Prometheus offers a rich data model and query language.
