Keeping an Eye on MySQL Database with Health Checks

These metrics focus on the efficiency of various cache systems within the database, helping to identify potential bottlenecks and areas for optimization. They measure the hit rate and fragmentation of different cache types, such as thread, table, MyISAM, and InnoDB caches, to ensure that frequently accessed data is readily available and cache usage is optimized.

• Thread Cache Hit Rate
• Thread Cache Ratio
• MyISAM Cache Hit Rate
• InnoDB Cache Rate Hit
• Table Cache Hit Rate
• QCache Fragmentation
