Query Performance Insight helps you to quickly identify what your longest running queries are, how they change over time, and what waits are affecting them.
For Query Performance Insight to function, data must exist in the Query Store.
The Query Performance Insight view in the Azure portal will surface visualizations on key information from Query Store.
In the portal page of your Azure Database for MariaDB server, select Query Performance Insight under the Intelligent Performance section of the menu bar.
The Long running queries tab shows the top 5 queries by average duration per execution, aggregated in 15-minute intervals. You can view more queries by selecting from the Number of Queries drop down. The chart colors may change for a specific Query ID when you do this.
You can select and drag in the chart to narrow down to a specific time window. Alternatively, use the zoom in and out icons to view a smaller or larger time period respectively.
Note
Wait statistics are meant for troubleshooting query performance issues. It is recommended to be turned on only for troubleshooting purposes.
If you receive the error message in the Azure portal "The issue encountered for 'Microsoft.DBforMariaDB'; cannot fulfill the request. If this issue continues or is unexpected, please contact support with this information." while viewing wait statistics, use a smaller time period.
Wait statistics provides a view of the wait events that occur during the execution of a specific query. Learn more about the wait event types in the MySQL engine documentation.
Select the Wait Statistics tab to view the corresponding visualizations on waits in the server.
Queries displayed in the wait statistics view are grouped by the queries that exhibit the largest waits during the specified time interval.
