Check apache-solr-version

Overview

Checks the installed Apache Solr 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 Apache Solr server itself to detect the installed version

Data Collection:

  • Detects the installed Apache Solr version by running <path> version (default path: /opt/solr/bin/solr)
  • Queries the endoflife.date API to determine EOL status and available releases
  • Caches the API response in a local SQLite database to reduce network calls
