Function

This API is used to list AS groups based on search criteria. The results are displayed by page.

Search criteria can be the AS group name, AS configuration ID, AS group status, start line number, and number of records.
If no search criteria are specified, a maximum of 20 AS groups can be listed by default.

URI

GET /autoscaling-api/v1/{project_id}/scaling_group

You can type the question mark (?) and ampersand (&) at the end of the URI to define multiple search criteria. AS groups can be searched by all optional parameters in the following table. For details, see the example request.
