Overview of the Performance Insights dashboard - Amazon Aurora

Overview of the Performance Insights dashboard

The dashboard is the easiest way to interact with Performance Insights. The following example shows the dashboard for a MySQL DB instance.

Enable Performance Insights during DB instance creation with console

Time range filter

By default, the Performance Insights dashboard shows DB load for the last hour. You can adjust this range to be as short as 5 minutes or as long as 2 years. You can also select a custom relative range.

You can select an absolute range with a beginning and ending date and time. The following example shows the time range beginning at midnight on 4/11/22 and ending at 11:59 PM on 4/14/22.

Counter metrics chart

With counter metrics, you can customize the Performance Insights dashboard to include up to 10 additional graphs. These graphs show a selection of dozens of operating system and database performance metrics. You can correlate this information with DB load to help identify and analyze performance problems.

The Counter metrics chart displays data for performance counters. The default metrics depend on the DB engine:

  • Aurora MySQL– db.SQL.Innodb_rows_read.avg

  • Aurora PostgreSQL – db.Transactions.xact_commit.avg

Counter metrics

To change the performance counters, choose Manage Metrics. You can select multiple OS metrics or Database metrics, as shown in the following screenshot. To see details for any metric, hover over the metric name.

Filter metrics

For descriptions of the counter metrics that you can add for each DB engine, see Performance Insights counter metrics.

Database load chart

The Database load chart shows how the database activity compares to DB instance capacity as represented by the Max vCPU line. By default, the stacked line chart represents DB load as average active sessions per unit of time. The DB load is sliced (grouped) by wait states.

DB load sliced by dimensions

You can choose to display load as active sessions grouped by any supported dimensions. The following table shows which dimensions are supported for the different engines.

Top dimensions table

The Top dimensions table slices DB load by different dimensions. A dimension is a category or "slice by" for different characteristics of DB load. If the dimension is SQL, Top SQL shows the SQL statements that contribute the most to DB load.

Top N dimensions

Choose any of the following dimension tabs.

Tab Description Supported engines


The SQL statements that are currently running


Top waits

The event for which the database backend is waiting


Top hosts

The host name of the connected client


Top users

The user logged in to the database


The name of the database to which the client is connected

Top applications

The name of the application that is connected to the database
