Based on the statistics gathered, specific recommendations are provided to increase the server's efficiency and performance. The script gives automated MySQL tuning on the level of what you would receive from a MySQL DBA. . Features: . * Weighted Health Score: Calculates an overall health score based on a wide range of configuration, performance and security indicators. * Predictive Capacity Planning: Forecasts resource usage and capacity headroom to help avoid future bottlenecks. * SSL/TLS Audit: Verifies TLS configuration, protocols and ciphers and flags weak or deprecated settings. * Storage Engines: Analyzes InnoDB, MyISAM and Aria statistics, including buffer pools, redo logs and key caches. * High Availability: Detects and diagnoses Galera Cluster, Percona XtraDB Cluster, InnoDB Cluster and Group Replication topologies. * Performance Schema: Reviews performance_schema statistics, stage profiling and wait events to spot bottlenecks. * OS Metrics: Correlates Linux operating system metrics such as memory, CPU, I/O and open file limits with server behaviour. * Vulnerability Checks: Cross-references installed versions against the bundled CVE database and reports known vulnerabilities. * Output Formats: Generates human-readable text, JSON and interactive HTML reports, and can be driven by automation via its CLI and MCP server interface.
