Prometheus is an open-source monitoring system with a built-in noSQL time-series database. It offers a multi-dimensional data model, a flexible query language, and diverse visualization possibilities. Prometheus collects metrics from http nedpoint. Most service dind't have this endpoint so you need optional programs that generate additional metrics cald exporters.

In this tutorial, you'll install, configure, and secure Prometheus and Node Exporter to generate metrics about your server's performance.
