The Autonomy Center in Database Autonomy Service (DAS) monitors your PolarDB for MySQL cluster, detects exceptions, and either surfaces optimization recommendations or—if you authorize it—automatically applies fixes to restore performance and limit impact. Use this page to enable autonomous actions and review the events DAS handles on your behalf.
Prerequisites
Before you begin, ensure that you have:
A PolarDB for MySQL cluster registered in DAS
How it works
When DAS detects an exception, it examines sessions, SQL statements, and instance capacity to find the root cause. DAS then either surfaces optimization suggestions or—if you grant authorization—acts autonomously to resolve the issue. Every autonomous action is recorded as an event, giving you a full audit trail of what happened and when.
Events fall into four categories:
| Category | Description |
|---|---|
| Abnormal events | Exceptions detected in the instance |
| Optimization events | Performance tuning actions taken or recommended |
| Auto scaling events | Capacity adjustments triggered automatically |
| Other events | Additional autonomy-related activities |
Enable autonomy and view events
Log on to the DAS console.
In the left-side navigation pane, click Instance Monitoring.
Find the instance you want to manage and click its instance ID. The instance details page opens.
In the left-side navigation pane, click Autonomy Center.
On the Autonomy Center page, click Autonomy Service Settings in the upper-right corner.

On the Autonomous Function Settings tab of the Autonomous Function Management panel, enable the autonomy service and click OK.
On the Autonomy Center tab, set a time range to view events within that period.
The trend chart shows the duration of each event alongside variations in major instance metrics during that window.
To inspect a specific event, click Details.
Next steps
Review the event list regularly to understand the types of exceptions DAS is handling on your cluster.
