CRITICAL (2 rules)WARNING (2 rules)INFO (2 rules)
6 automated checks cover this variable.
Overview
- Purpose
- Server product and release string reported by the instance (for example from
versionorversion_comment). Used for lifecycle and compatibility review; it is not configured withSET GLOBAL. - Dynamic (MySQL 8.4 reference)
- Not applicable — reported by the server.
- Default value
- N/A (read from the running server).
- Version and product notes
- Exact format depends on MySQL, MariaDB, or Percona Server build.
- Documentation
- Primary reference depends on product (MySQL, MariaDB, Percona, or OS documentation).
What is checked
Rules that reference this variable, with their severity and what each rule detects:
- INFO Keep your instance updated to the latest minor/patch version for security and performance improvements.
- CRITICAL Run a Long-Term Support line: 9.7 LTS (April 2026) is current, and 8.4 LTS remains supported. Innovation releases are maintained only until the next one ships. Note that MySQL switched to calendar versioning after 9.7, so releases now look like 26.7 (July 2026).
- INFO No urgency: 8.4 LTS remains supported. When you plan the next upgrade, 8.4 LTS to 9.7 LTS is the supported path (you cannot skip an LTS). Check the Upgrade Advisor first — innodb_log_file_size, innodb_log_files_in_group, innodb_undo_tablespaces and replica_parallel_type are all removed in the 9.x line.
- WARNING Update to the latest patch release of your current major version.
- CRITICAL Upgrade to MariaDB 10.6 LTS (EOL Jul 2026), 10.11 LTS (EOL Feb 2028), or 11.4 LTS (EOL May 2029).
- WARNING Switch to a MariaDB LTS branch: 10.6, 10.11, or 11.4 for long-term stability and support.
Tuning guidance
- Recommended actions:
- Keep your instance updated to the latest minor/patch version for security and performance improvements.
- Run a Long-Term Support line: 9.7 LTS (April 2026) is current, and 8.4 LTS remains supported. Innovation releases are maintained only until the next one ships. Note that MySQL switched to calendar versioning after 9.7, so releases now look like 26.7 (July 2026).
- No urgency: 8.4 LTS remains supported. When you plan the next upgrade, 8.4 LTS to 9.7 LTS is the supported path (you cannot skip an LTS). Check the Upgrade Advisor first — innodb_log_file_size, innodb_log_files_in_group, innodb_undo_tablespaces and replica_parallel_type are all removed in the 9.x line.
- Update to the latest patch release of your current major version.
- Upgrade to MariaDB 10.6 LTS (EOL Jul 2026), 10.11 LTS (EOL Feb 2028), or 11.4 LTS (EOL May 2029).
- Switch to a MariaDB LTS branch: 10.6, 10.11, or 11.4 for long-term stability and support.
- Trade-offs: Running an end-of-life MySQL version means no security patches. Upgrading requires planning, testing, and possible application changes for deprecated features.
