Icinga Web
The screenshot shows an overview of the Icinga web interface, in which the various components and functions of the dashboard are clearly explained.
Icinga Web offers simple tab navigation to quickly jump to important information.
If you click on elements in Icinga, a new view opens on the right-hand side and allows you to quickly jump between views.
Performance data can be embedded and displayed directly in Icinga Web via modules such as Grafana.
Get a quick overview of whether a check is OK or whether problems have been found.
In the list view of the service checks, you can quickly see whether there are any current problems.
Icinga indicates in the navigation menu when modules report information, warnings or problems.
Personalized registration! Icinga Web allows connection to directory services such as Active Directory and thus offers full multi-client capability.
The Icinga Web navigation bar can be extended with custom PHP modules or filtered views in menu structures.
Using the action bar, various interactions such as setting downtimes, re-scheduling checks or acknowledging problems can be carried out quickly and easily.
Quickly recognize when a problem has occurred or how long it has been okay again.
Start small, make clear progress
You don’t have to start a big project right away. Choose the entry point that suits your situation – each step provides you with a concrete result.

Questions & Answers
The most frequently asked questions about Icinga.
Is Icinga free of charge?
Icinga is licensed under the GPL and all sources are freely available. The Icinga project provides ready-to-use packages for the most important community Linux distributions free of charge. For the official packages for Enterprise Linux distributions (RHEL, SLES, Amazon Linux) and for certain Icinga modules, either an Icinga subscription or an Icinga support contract is required.
Is Icinga open source?
Icinga is open source and is licensed under the terms of the GNU General Public License Version 2.
What is the difference between Nagios and Icinga?
Both Nagios and Icinga are open source monitoring tools, whereby Icinga was originally created as a fork of Nagios. Icinga offers a more modern user interface, supports a more powerful API and offers better scalability in large environments. However, Nagios is still widely used and has a large community as well as a large number of plugins and extensions. However, all Nagios plugins can also be used with Icinga, so migrating from Nagios to Icinga is the best way to switch to an up-to-date and active platform.
What can Icinga monitor?
Icinga can monitor a wide range of IT infrastructures, including servers, networks, applications and services. Icinga monitors both physical and virtual environments and can capture metrics such as CPU utilization, disk space, network availability and service response times. Custom plugins allow Icinga to be flexibly extended to monitor almost any type of system or process.
How does Icinga work?
Icinga is an open source monitoring tool that monitors IT infrastructures by checking hosts, services and networks in real time. It collects and analyzes data such as availability, performance and resource usage and warns of problems or failures via notifications. Thanks to its flexible architecture and integration with other tools such as Grafana and Prometheus, Icinga is suitable for both small and complex environments for monitoring and problem detection.
What does Icinga do?
Icinga monitors IT infrastructures by continuously checking servers, networks and applications for availability, performance and errors. It notifies administrators in the event of problems or failures, enabling a rapid response before critical faults occur. It also offers dashboards for visualizing system statuses and can be flexibly adapted to different environments using plugins and integrations.
