From the initial installation to the running monitoring stack:
Here you will find all instructions for the basic installation of Icinga.
Compact and practical.
Last updated: July 30, 2026 · Reading time: 2–3 minutes Alertmanager and Icinga do not communicate with each other by default. If you want to process Prometheus alerts centrally via Icinga, you need a bridge between the two systems. That's exactly what the Alertmanager-Icinga Bridge does: It receives alerts from Alertmanager and automatically creates them as services in Icinga. In this post, we'll explain why we're continuing to develop the Signalilo tool under a new name, what changes have...
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...
Last updated: August 5, 2026 · Reading time: 6–8 minutes Observability vs. Monitoring: Two terms that are constantly used interchangeably in everyday IT, but don't mean the same thing. We'll break down the etymology, cite the earliest known definition from 1959, and use OpenTelemetry and Graylog to demonstrate how these two concepts interact in practice. The term observability is on everyone's lips and is often touted as a modern solution to dusty old, static monitoring. All manufacturers...
After we forked the Grafana module for Icinga Web last year, we thought about whether there are other ways to graphically display Icinga performance data on the web. Running a Grafana instance alongside Icinga just for rendering graphs is a lot of effort and additional operational complexity, no matter how great you think Grafana is. In addition, the installation of the grafana-image-renderer is not always trivial. So we took a closer look at the topic and tried to create an Icinga Web module...
