What is the Prometheus system?

Prometheus is an open-source monitoring and alerting tool originally developed by SoundCloud. It supports multiple data sources, can collect, store, and query time series data, and provides a powerful query language and flexible alerting mechanisms. Prometheus can be used to monitor performance metrics of various systems and services, helping users to detect and address issues promptly. Its simple, reliable, and efficient design has led to widespread use in cloud-native and containerized environments.
