MySQLTuner is a Perl script that audits a running MySQL, MariaDB, or Percona Server instance and reports configuration variables, status metrics, and performance/stability recommendations. It supports 900+ indicators including health scoring, capacity planning, and SSL/TLS audits across many storage engines and cluster setups.

Use cases

• tune mysql configuration for better performance
• audit mariadb server settings and get recommendations
• check mysql memory and buffer sizing
• review mysql security and ssl/tls configuration
• diagnose slow mysql server stability issues
• assess innodb and myisam performance health

When to choose

• you run MySQL, MariaDB, or Percona Server and want quick, actionable tuning advice
• you need a lightweight, dependency-free script runnable directly on the database host
• you want broad coverage of storage engines, Galera clusters, and OS-level metrics

When to avoid

• you need continuous monitoring and alerting rather than point-in-time audits
• you want automated tuning - MySQLTuner only recommends, it does not change configuration
• you run a database other than MySQL/MariaDB/Percona
