EventBridge is integrated with Tencent Cloud Observability Platform (TCOP). You can configure the alert rules in the TCOP console.
Overview
Upon the activation of EventBridge, a default Tencent Cloud service event bus in created automatically in the Guangzhou region. Events of all services connected to the event bus are deliver events. You can also set event rules and delivery targets to configure an alarm link.
Configuring Alerting Rules
1. View the event list
Log in to the EventBridge console, go to the default Tencent Cloud service event bus, and view the events of all connected Tencent Cloud services.
Event structure version (CloudEvents version), which is 1.0.2.
String
ID
ID returned by PUT Event.
String
type
Type of the event passed in PUT Event. The standard format of a Tencent Cloud service alarm event is ${ProductName}:ErrorEvent:${EventType}, where colons (:) are used to separate type fields.
String
source
Event source (which is required for a Tencent Cloud service event and is the abbreviation of subject). The value is xxx.cloud.tencent by default for a Tencent Cloud service.
String

JSON
2. Configure an alert event rule
Go to the Event Rule page, select the target event bus. Create an event rule.
Sample alert rule
To receive and deliver all CVM alert events, the rule should be as below:
{
"source":"cvm.cloud.tencent"
}
To receive and deliver only unreachable ping events from CVM, the rule should be as below. In this case, other events are discarded.
{
"source":"cvm.cloud.tencent",
"type":"cvm:ErrorEvent:PingUnreachable"
}
Receiving events from the specified instance: Events from the CVM resource "ins-XXX" are received and delivered. Other events are discarded. The format of subject varies for different event sources. You can check the formats in the complete event delivered to CLS.
{
"source":"cvm.cloud.tencent",
"subject":"ins-xxxxxx"
}
You can also specify multiple resources by using an array.
{
"source":"cvm.cloud.tencent",
"subject":["ins-xxxxxx","ins-xxxxxx"]
}
For more information about the matching rules, see Event Pattern.
3. Configure delivery targets
In event alarm scenarios, we recommend you configure two delivery targets: CLS and Notification message.
CLS
Notification message
EventBridge provides a dedicated CLS log set for the default Tencent Cloud service event bus, which helps you trace back delivered alarm events.
Description
EventBridge offers a free tier of 1 GB per 30 days for storage in the dedicated logset to ensure that you can view and manage basic alarm events free of charge. Excessive storage will be billed according to the CLS billing rules. For more information, see Billing Overview.
You can configure a notification message to push your alarm events in the specified delivery method to promptly reach users.
4. Test the configuration result
After completing the configuration, return to the EventBridge console, select the bound event bus, and click Deliver Event. You can select a bound event rule template and click Deliver Event for test.
Note
The test template displays only the data field, while other fields are fixed and cannot be customized.
After completing the configuration, you can view and configure the push of alarm events in the EventBridge console.
Sample push content text
