This topic describes how to create an event notification in a scaling group. After
an event of the specified type occurs, Auto Scaling automatically sends a notification
to the specified Message Service (MNS) topic, MNS queue, or Cloud Monitor.
Prerequisites
If you want Auto Scaling to automatically send notifications to an MNS topic or queue,
you must create the MNS topic or queue in advance. Make sure that the MNS topic or
queue belongs to the same region where the scaling group resides. For more information,
see Create a topic or Create a queue.
Background information
- Only a limited number of event notifications can be created in a scaling group. For
more information, see Limits.
- Receivers in a scaling group must be unique. For example, Cloud Monitor, the same
MNS topic, or the same MNS queue cannot be used to receive different event notifications
in a scaling group.
Procedure
- Log on to the Auto Scaling console.
- In the left-side navigation pane, click Scaling Groups.
- In the top navigation bar, select a region.
- 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.
- In the upper part of the page, click the Event Notifications tab.
- Click Create Event Notification.
- Configure parameters for the event notification.
