This topic describes how to view the details of a scaling activity. If a scaling activity is triggered by a scheduled or event-triggered task, you can view the details of the scaling activity to check its execution result.

Background information

A scaling activity can have the following states: Rejected, Executing, Successful, Warning, and Failed. For more information, see Overview.
Note During a scaling activity, if some ECS instances fail to be added to a scaling group, Auto Scaling performs rollback on these ECS instances. After the scaling activity is complete, the scaling activity enters the Warning state. For more information, see Overview.

Procedure

  1. Log on to the Auto Scaling console.
  2. In the left-side navigation pane, click Scaling Groups.
  3. In the top navigation bar, select a region.
  4. Find the scaling group and use one of the following methods to open the details page of the scaling group:
    • Click the ID of the scaling group in the Scaling Group Name/ID column.
    • Click Details in the Actions column.
  5. In the upper part of the page, click the Scaling Activities tab.
  6. Find the scaling activity whose details you want to view and click its ID in the Scaling Activity ID column.
