Querying AS Policies Bound to an AS Group

Function

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

  • Search criteria can be the AS policy name, policy type, policy ID, start line number, and number of records.
  • If no search criteria are specified, a maximum of 20 AS policies for a specified AS group can be queried for a tenant by default.

URI

GET /autoscaling-api/v1/{project_id}/scaling_policy/{scaling_group_id}/list

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