Prometheus was originally developed in 2012 and has grown in popularity since then. It's an open-source systems toolkit that monitors and alerts. While it was developed for SoundCloud, the project is now independent and standalone. Why would you need this model? It comes with several features, but perhaps the most important ones are the fact that it offers multiple graphing modes, dashboard support, and does not rely on distributed storage. Instead, it uses autonomous single server nodes.

PromQL is a functional query language that’s meant for use with the Prometheus monitoring tool. In fact, PromQL is short for “Prometheus Query Language.” The point of this language is to make it easy for users to choose and collect time-series data in Prometheus, which can then be displayed in a graph or as tabular data in the browser for this tool.
