About:
Mysqltuner is a Perl script that analyzes a MySQL installation and provides recommendations for performance tuning and stability improvements. It reviews configuration variables, storage engine status, and query efficiency to identify bottlenecks. The tool helps database administrators optimize memory usage, connection handling, and query caching without manual inspection of dozens of system variables.

Key Features:

Automated analysis of MySQL configuration and status variables
Performance tuning recommendations with priority levels
Security vulnerability detection and suggestions
Storage engine health and index usage analysis
Support for MariaDB and Percona Server

Use Cases:

Troubleshooting slow MySQL performance on production servers
Validating configuration changes after MySQL upgrades
Initial database server setup and optimization
Regular health checks for existing MySQL installations

Alternatives:

Percona Toolkit – More comprehensive suite of advanced tools, but requires paid subscription for full features
MySQL Workbench – GUI-based tool with visual explain plans, but lacks automated tuning recommendations
