When Data Transmission Service (DTS) detects a risk that might prevent an instance from running correctly, it triggers an O&M event and sends a notification through the console, email, or internal messages. You can view event details, including the affected instance, event timeline, and suggested actions, and modify the execution time in the DTS console.
Prerequisites
Log on to the Message Center and enable notifications for ApsaraDB Fault or Maintenance Notifications. We recommend that you configure the database O&M administrator as the recipient. Otherwise, you will not receive these notifications.
Usage notes
O&M events with an Event Level of Critical require immediate attention.

DTS typically notifies you of an O&M event at least one day before execution. Some events require your action. After you receive a notification, log on to the DTS console promptly to view the suggestions and make the required changes.

We recommend that you set a Schedule Execution Time to allow the system to perform the O&M event during off-peak hours before the deadline. Complete any changes listed under Suggestions to ensure your DTS instance runs correctly. Otherwise, the system executes the event at the default Planned Execution Time, which may cause interruptions or other issues. The DTS Service Level Agreement (SLA) does not cover losses from such issues.

You can modify the scheduled time only for scheduled O&M events with an Event Status of Scheduled. The new time must be at least 5 minutes later than the current time and earlier than the Latest Available Time.
