Amazon RDS (Relational Database Service) Performance Insights now supports configuration at the Aurora cluster level. Customers can configure Performance Insights or Enhanced Monitoring on all the instances within an Aurora cluster with a single click in the console or through APIs.
With this launch, customers no longer need to spend manual effort to configure Performance Insights or Enhanced Monitoring individually for all instances within an Aurora cluster. When Aurora Auto Scaling adds new Aurora Replicas, the new instances automatically inherit the cluster-level configuration of Performance Insights and Enhanced Monitoring. This feature allows customers to enforce a uniform monitoring configuration across all instances within a cluster.
Amazon RDS Performance Insights is a database performance tuning and monitoring feature of RDS that allows you to visually assess the load on your database and determine when and where to take action. With one click in the Amazon RDS Management Console, you can add a fully-managed performance monitoring solution to your Amazon RDS database.
