Amazon RDS Performance Insights supports additional dimensions to identify the source of high-frequency, long-running, and stuck SQL queries faster. The new Performance Insights dimensions are available on Amazon RDS for PostgreSQL and Amazon Aurora with PostgreSQL compatibility

Previously, gathering performance data on a database required configuration and maintenance of monitoring applications and related resources. Correlating performance data took hours without specialized expertise. To find a query of interest, such as a stuck or long-running SQL query, meant investigating each query one at a time.  

RDS Performance Insights allows non-experts and experts to identify top SQL loads and from where they originated on a visual dashboard in seconds. Now, RDS Performance Insights supports segmenting the performance data by additional dimensions, such as database name, application, and session type. You can determine if a specific application is generating unusual high load or is issuing SQL queries that take unusually long to complete. You can then make improvements to your application such as optimizing a slow SQL query, changing connection patterns, adding an index to your database, and scaling your database. 

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. RDS Performance Insights is included with supported Amazon Aurora clusters and Amazon RDS instances and stores seven days of performance history in a rolling window at no additional cost. If you need longer-term retention, you can choose to pay for up to two years of performance history retention.
