Querying AS Policy Execution Logs

Function

This API is used to query the historical records of AS policy execution based on search criteria. The results are displayed by page.

  • Search criteria can be the log ID, AS resource type, AS resource ID, policy execution type, start time, end time, start line number, and number of records.
  • If no search criteria are specified, a maximum of 20 AS policy execution logs can be queried by default.

URI

GET /autoscaling-api/v1/{project_id}/scaling_policy_execute_log/{scaling_policy_id}

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