This topic describes how to receive notifications about scaling activitiesby using internal messages and emails.

Prerequisites

No event notifications are created.

Background information

You can use internal messages and emails to receive notifications. You must handle the notifications on your own after you receive them.

You can also use the event notification feature to configure events related to Auto Scaling to be automatically sent to Cloud Monitor or Message Service (MNS). For more information, see Event notification overview. After you customize handling policies in these services, these services can initiate handling processes after the event notifications are received.
Note If you have created event notifications, you cannot set notification receiving. To set notification receiving, you must delete all event notifications.

  1. Log on to the Auto Scaling console.
  2. In the left-side navigation pane, click Scaling Groups.

    You can configure notifications for the following scaling scenarios:
    • Scaling Activity Success: Auto Scaling adds or removes ECS instances to or from the scaling group.
    • Scaling Activity Failed: A scaling activity is triggered, but Auto Scaling fails to add or remove ECS instances to or from the scaling group.
    • Scaling Activity Rejected: The request of a scaling activity is received but rejected because the trigger conditions are not met.
