Querying AS Groups

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.
