Check icinga-version

Overview

Checks the installed Icinga version against the endoflife.date API and alerts if the version is end-of-life or if newer major, minor, or patch releases are available. By default, alerts 30 days before the official EOL date. The offset is configurable.

Important Notes:

  • Must run on the host where the Icinga2 daemon is installed

  • The check returns UNKNOWN if the icinga2 binary is not found on the system

Data Collection:

  • Runs icinga2 --version locally to determine the installed version

  • Queries the endoflife.date API (https://endoflife.date/api/icinga.json) for EOL and release information

  • Caches API responses in a SQLite database to avoid repeated requests
