Top activity shows SQL statements by default. Breaking down database load by wait types can help you understand what kind of database mechanisms are chiefly contributing to the load. On the bottom, a top activity table shows what is contributing to database load for the time interval on the load chart.īy default, the load chart is color coded by wait type.At the top, a load chart shows the recent history of database load in units of average active sessions (AAS).Instances that have Performance Insights enabled show current activity measured in Sessions. Choose the bar under Current Activity for a DB instance to open the Performance Insights dashboard for that DB instance.Choose Performance Insights in the left navigation pane to open the dashboard and view a list of DB instances that have Performance Insights enabled.You can access Performance Insights through the Amazon RDS console in two places: Just sign in to the Amazon RDS console, and go to the Performance Insights dashboard to start monitoring performance with just one click. Or, use the EnablePerformanceInsights parameter of the CreateDbInstance or ModifyDbInstance API methods. You can enable it for other instances on the console by choosing Modify on the Instance actions menu. Performance Insights is enabled by default for instances that you create in the AWS Management Console. It also requires no configuration or maintenance, and it’s currently available with Amazon Aurora PostgreSQL. Using a dashboard that visualizes database load-along with which SQL statements are causing the load and why-Performance Insights makes detecting performance problems easy for both experts and non-experts.īecause it collects performance data using lightweight methods, Performance Insights doesn’t impact the performance of your applications.
