Amazon Relational Database Service (Amazon RDS) Performance Insights now makes it easier for you to see the database performance metrics for the exact timeframe you want to analyze, by choosing a custom time window within your retention period. Previously, you could only see metrics in Performance Insights by choosing relative time intervals such as the past 1 hour, the past 24 hours, etc. Amazon RDS Performance Insights is a database performance tuning and monitoring feature of Amazon RDS and Amazon Aurora that helps you quickly assess the load on your database and determine when and where to take action. This helps non-experts to measure database performance with an easy-to-understand dashboard that visualizes database load. With one click, you can add a fully-managed performance monitoring solution to your Amazon Aurora clusters and Amazon RDS instances. Amazon RDS Performance Insights automatically gathers all necessary performance metrics and visualizes them in a dynamic dashboard on the Amazon RDS console. You can identify your database’s top performance bottlenecks from a single graph.
