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: July 9, 2026 · Reading time: 2–3 minutes Elasticsearch is running, Kibana is set up, but how does the data actually get into the stack? The answer lies in what are known as "Beats": lightweight data collectors that run in the background and forward data to Elasticsearch. The easiest way to get started is with Filebeat and Metricbeat. This article shows you how to set up Filebeat for log files and Metricbeat for system metrics, and how to view both in Kibana. Why use Filebeat...

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: 05.03.2026 This blog post explains whether Icinga is free. As I sit here and start writing this blog post, I still can't believe that today is about this topic. Is Icinga free of charge? For me, as someone who has been involved with open source software for almost 25 years now (yes, I'm old!), this question seems strange and yet the topic is interesting. As obvious as the answer to this is for me, the figures, data and facts from the usual analytics tools are just as clear. The...
Introduction The way in which IT infrastructure is provided and operated has changed significantly in recent decades. In the early years of system administration, everyday life consisted of manually installing individual servers, importing software packages, editing configurations directly in files and starting services. This was not only time-consuming, but also error-prone and difficult to reproduce. Even a small difference in a configuration could lead to problems that were almost...
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...
