Amazon RDS (Relational Database Service) Performance Insights now generates recommendations that inform you of impending database performance and availability issues before they become critical. RDS Performance Insights continuously monitors database instances for potential issues that can lead to degraded database health in the future. When it detects such conditions, it generates new recommendations that describe the nature of the impending problem, and includes specific actions you can take to mitigate that problem. These recommendations are available to Performance Insights paid tier customers.
