Database Autonomy Service (DAS) provides diagnostic reports for ApsaraDB RDS for MySQL instances. When you suspect performance issues or want to perform routine health checks, you can generate a diagnostic report to evaluate your instance over a specified time window. The report surfaces a health score, slow query logs, tablespace usage by table, and Performance Trend data — giving you a consolidated view to identify and address issues quickly.
Prerequisites
Before you begin, ensure that you have:
-
An ApsaraDB RDS for MySQL instance running RDS High-availability Edition or RDS Cluster Edition
RDS Basic Edition does not support diagnostic reports.
Create a diagnostic report
-
Go to the Instances page. In the top navigation bar, select the region where your instance resides, then click the instance ID.
-
In the left-side navigation pane, choose Autonomy Services > Diagnostic Reports.
-
Click Create Reports. To schedule reports instead of creating them on demand, click Auto-generating Report Settings and configure the parameters in the Scheduled Trigger section.
The time range for a report cannot exceed one day. A shorter time range produces more detailed statistics.
-
Refresh the page to track diagnostic progress. After the task completes, find the report and click View Report in the Actions column.
