    EventBridge：Manage event rules

    更新時間：Nov 06, 2024

    An event rule is used to monitor a specific type of events. If an event that matches an event rule occurs, the event is routed to an event target that is associated with the event rule. An event rule can be associated with one or more event targets. You can manage event rules in the EventBridge console. This topic describes how to create, view, and delete event rules.

    Prerequisites

    EventBridge is activated and the required permissions are granted to a Resource Access Management (RAM) user. For more information, see Activate EventBridge and grant permissions to a RAM user.

    Create an event rule

    1. Log on to the EventBridge console.
    2. In the left-side navigation pane, click Event Buses.
    3. In the top navigation bar, select a region.
    4. On the Event Buses page, click the name of the target event bus.

    5. In the left-side navigation pane, click Event Rules.

    6. In the left-side navigation pane, click Event Rules. On the page that appears, click Create Rule.

    7. In the Create Rule wizard, perform the following steps:

      1. In the Configure Basic Info step, enter a rule name in the Name field and a rule description in the Description field. Then, click Next Step.

      2. In the Configure Event Pattern step, configure the parameters and click Next Step.

        • Select Alibaba Cloud Service Event Sources for the Event Source Type parameter.

          Select an Alibaba Cloud service from the Event Source drop-down list and an event type from the Event Type drop-down list.

          Note

          Events from Alibaba Cloud services cannot be published to custom event buses. Therefore, you cannot set the Event Source Type parameter to Alibaba Cloud Service Event Source if the event bus that you use is a custom event bus.

        • Select Custom Event Source for the Event Source Type parameter.

          Select a custom event source from the Event Source drop-down list and specify an event pattern in the Pattern Content code editor.

          For more information, see Event patterns.

      3. In the Configure Targets step, configure event targets and click Create.

        Important

        • You can configure up to five event targets for an event rule.

        • The event targets that you want to configure for an event rule must reside in the same region as the event rule.

        EventBridge supports the following event targets:

        • Function Compute: computes and processes events.
