Overview

Data Transfer Service (DTS) supports monitoring events during data migration, synchronization, and subscription tasks and setting alarm rules. When an event triggers or metrics reach the set threshold, it promptly notifies users to take actions.
Note:
Currently, event alarms are supported for migration, synchronization, and subscription links of MySQL/MariaDB/Percona/TDSQL-C for MySQL/TDSQL Boundless.

Supported Event Alarms

Event Name
Description
Data migration task interrupted
During the data migration task, when an abnormal interruption occurs (excluding scenarios where the user actively interrupts the task), an alarm is triggered.
Data synchronization task interrupted
During the data synchronization task, when an abnormal interruption occurs (excluding scenarios where the user actively interrupts the task), an alarm is triggered.
Data subscription task interrupted
During the data subscription task, when an abnormal interruption occurs (excluding scenarios where the user actively interrupts the task), an alarm is triggered.
DTS service maintenance about to start
The DTS service is about to perform maintenance and upgrades. An alarm is triggered 24 hours prior to the user-scheduled maintenance time to notify users that DTS is about to perform service maintenance and upgrades.

When the interruption time of the DTS task exceeds 1 day but is less than 14 days, an alarm is triggered.
Status of the DTS task changing to Failed
When the interruption time of the DTS task reaches 14 days, an alarm is triggered to notify users that the task cannot be recovered, and the task status will change to Terminated.

During console operations, an alarm is triggered upon abnormal interruption.
Mini program operation events (delivered based on CloudAudit)
An alarm is triggered upon abnormal interruption during mini program operations.

After a task starts but before it ends, when the user actively terminates the task or takes it offline, a task end alarm is triggered.
End of the data synchronization task
After a task starts but before it ends, when the user actively ends the task or takes it offline, a task end alarm is triggered.
End of the data subscription task
