Overview
DTS can use EventBridge to configure alarms for abnormal task interruption events. EventBridge will send notifications to recipients as soon as an event is triggered so that they can take timely measures.
After EventBridge is activated, it will automatically create a default Tencent Cloud service event bus in Guangzhou region, to which alarm events generated by DTS will be automatically published.
This document describes how to set notification rules for event alarms, that is, filter alarmed tasks and set the alarm publishing method, alarm notification method, and recipient group.
Prerequisite
Directions
Viewing the event list
2. Click Event Bus on the left sidebar. The default event bus is stored in the Guangzhou region. You don't need to switch the region.

If you have already authorized it, skip this step. 3. Click the Event bus ID and go to Basic information > Event Source > Cloud Monitor to view the DTS monitoring event.
Configuring event alarm rules
2. On the Event Rule page, select a region and event bus and click Create. The default event bus is stored in the Guangzhou region. You don't need to switch the region.
3. On the Basic information page, enter the rule name and description. In the Event matching module below, you can select Template or Custom Event for the Mode field as needed.
If you select Template, you need to configure the Tencent Cloud service and Event Type fields. You can select all events or specific event types for Event Type.

Sample Syntax for Custom Event Alarms
Below are the sample syntaxes in different scenarios:
Receive alarms of all DTS events. The following syntax represents that alarms can be pushed for all DTS alarm events according to the event rule.
{
"source":"dts.cloud.tencent"
}
Receive event alarms of DTS migration, sync, and subscription tasks. The three fields under the type of the following syntax represent the migration, sync, and subscription task interruption events respectively. If you don't need to receive alarms of any of these events, delete the corresponding syntax content.
{
"source":"dts.cloud.tencent",
"type":[
"dts:ErrorEvent:MigratejobInterruption",
"dts:ErrorEvent:ReplicationInterruption",
"dts:ErrorEvent:SubscriptionInterruption"
]
}
Receive event alarms of a single DTS task. The following syntax represents that alarms can only be pushed for the alarm event generated by the specified task (ID: sync-jt12XXgt). Those triggered by other events will be discarded and cannot be pushed to recipients.
{
"source":"dts.cloud.tencent",
"subject":"sync-jt12XXgt"
}
Receive event alarms of multiple DTS tasks.
{
"source":"dts.cloud.tencent",
"subject":["sync-jt12XXgt","dts-a5uqXXhs"]
}
Receive event alarms of DTS migration tasks in the specified region. Here, region refers to the target instance region.
{
"source":"dts.cloud.tencent",
"type":"dts:ErrorEvent:MigratejobInterruption",
"region":"ap-guangzhou"
}
