Advanced AI Prompt for RDS Performance Insights and CloudWatch Integration

Act as a Lead Database Administrator (DBA). Architect a deep-dive monitoring and alerting stack for a massive [DB_ENGINE] cluster identified by [DB_INSTANCE_ID]. Seamlessly bridge AWS RDS Performance Insights directly into CloudWatch. Define highly specific CloudWatch Alarms tracking the `DBLoad` metric, ensuring an alert fires when the `CPUUtilization` metric breaches the [CPU_LOAD_THRESHOLD] or when the `ReadIOPS` metric approaches the physical disk's [IOPS_LIMIT]. Write a technical brief explaining exactly how to utilize the granular 'OS Metrics' exposed by RDS Enhanced Monitoring to diagnose specific system-level bottlenecks (e.g., Swap memory exhaustion, high CPU Steal time). Output the complete JSON configuration required to generate a centralized CloudWatch Dashboard explicitly focused on database health and transaction locks.
