Icinga2 - The definitive guide to monitoring

Install and configure the Icinga engine, including repository setup, base packages, and plugins for remote checks; enable features, secure with SELinux, and set up MariaDB for monitoring.

Install and configure the icinga2 web ui to manage monitoring instances via a browser, install dependencies, set up apache, start services, configure the firewall, and generate a setup token.

Create a user for the daemon, install package, copy the service definition to the system, configure environment and config files, then restart, reload, enable, and start the service; check status.

Import host groups and hosts from the core API into Icinga via automation, set merge and purge sync rules, and run sync and import to reflect changes.

Learn to configure an agent-based Icinga2 monitoring setup: install the Icinga agent on a Linux node, generate a ticket, and register the host with disk checks in the web UI.
