Prometheus

Prometheus is a high-performance monitoring and alerting system designed to collect metrics and observe the performance of applications, servers, and networks. It was developed by SoundCloud and quickly became the standard in the DevOps world.

Prometheus collects metrics in time series format, stores them in its own database, and allows you to build visualizations.

The main feature of Prometheus is its pull mechanism: it polls systems and services itself to obtain data.

For businesses, Prometheus provides the ability to see the real status of all systems, which helps prevent failures and predict load growth.

Prometheus supports the PromQL query language and integration with alerting and event monitoring systems.

The tool is easily integrated into cloud and microservice architectures thanks to a large number of ready-made exporters and its modular architecture.
