Check mysql-version

Overview

Checks the installed MySQL/MariaDB 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 MySQL/MariaDB server itself to detect the installed version

Data Collection:

  • Detects the installed version by running mysqld --version, mariadb --version, or mysql --version
  • Queries the endoflife.date API for MySQL or MariaDB lifecycle data
  • Caches the API response in a local SQLite database to reduce API calls
