Integrate Icinga and Prometheus

by Markus Opolka

Last updated: 23.04.2026 Icinga and Prometheus are both excellent monitoring solutions. However, the focus of the tools is different. When it comes to monitoring real-time metrics or short-lived services such as containers, Prometheus is the tool of choice. Icinga is often better suited for large-scale status monitoring of the basic infrastructure. However, both solutions do not have to be contrary to each other, but complementary. In this article, we will look at how we can integrate both...
