Dear Alibaba Cloud User,

To more accurately reflect the actual purpose of these APIs, the following CloudMonitor OpenAPI operations will be reclassified from Management Events to Data Events in ActionTrail. This change will take effect on June 23, 2026.

Affected APIs:

Impact Summary:

1. After the change takes effect, invocations of the above APIs will no longer appear in Management Events, and will instead be recorded exclusively under Data Events in ActionTrail.
2. If you currently deliver Management Events to Log Service (SLS) or Object Storage Service (OSS) via ActionTrail—and rely on logs of these APIs for audit or compliance analysis—you must enable Data Event delivery before June 23, 2026, to ensure uninterrupted and complete audit logging.

Recommended Actions:

• Review your existing ActionTrail trails and verify whether Data Event delivery is enabled.
• If you have alerting rules, dashboards, or automated workflows that trigger on Management Event logs for the listed APIs, update them to monitor Data Events instead.

This upgrade does not affect the overall cost, nor does it affect the use of other functions.Should you have any questions, please submit a support ticket.
