What This Dashboard Monitors
This dashboard tracks essential MySQL metrics to help you:
- Monitor Connection Health: Track database connections and connection errors
- Analyze Lock Performance: Monitor MySQL locks and row-level locking behavior
- Track Buffer Pool Usage: Analyze InnoDB buffer pool efficiency and page management
- Monitor Table I/O Operations: Track table-level I/O wait events and performance
- Analyze Resource Utilization: Monitor threads, handlers, and prepared statements
- Database Performance Optimization: Identify bottlenecks and optimize database operations
Metrics Included
Connection Metrics
- Connection/Errors: Shows database connection count and connection errors over time
Performance Metrics
- Count by Handlers: Shows MySQL handler operations count by type over time
- Row Operations: Shows row-level operations (read, insert, delete, update) over time
- Count of Operations: Shows count of database operations by operation type
Lock Metrics
- MySQL Locks: Shows MySQL lock types (immediate, waited) over time
- Row Locks: Shows InnoDB row lock operations (waits, time) over time
Resource Metrics
