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.

  Table 2 Response parameters

  Parameter	Type	Description
  total_number	Integer	Specifies the total number of query records.
  start_number	Integer	Specifies the start line number.
  limit	Integer	Specifies the maximum number of resources to be queried.
  scaling_policy_execute_log	Array of scaling_policy_execute_log objects	Specifies the AS policy execution logs. For details, see Table 3.

  Table 3 scaling_policy_execute_log field description

  Parameter	Type	Description
  status	String	Specifies the AS policy execution status. SUCCESS: The AS policy has been executed. FAIL: Executing the AS policy failed. EXECUTING: The AS policy is being executed.
  failed_reason	String	Specifies the AS policy execution failure.
  execute_type	String	Specifies the AS policy execution type. SCHEDULED: automatically triggered at a specified time point RECURRENCE: automatically triggered at a specified time period ALARM: alarm-triggered MANUAL: manually triggered
  execute_time	String	Specifies the time when an AS policy was executed. The time format complies with UTC.
  id	String	Specifies the ID of an AS policy execution log.
  tenant_id	String	Specifies the project ID.
  scaling_policy_id	String	Specifies the AS policy ID.
  scaling_resource_type	String	Specifies the scaling resource type. AS group: SCALING_GROUP Bandwidth: BANDWIDTH
  scaling_resource_id	String	Specifies the scaling resource ID.
  old_value	String	Specifies the source value.
  desire_value	String	Specifies the target value.
  limit_value	String	Specifies the operation restrictions. If scaling_resource_type is set to BANDWIDTH and operation is not SET, this parameter takes effect and the unit is Mbit/s. In this case: If operation is set to ADD, this parameter indicates the maximum bandwidth allowed. If operation is set to REDUCE, this parameter indicates the minimum bandwidth allowed.
  type	String	Specifies the AS policy execution type. ADD: indicates adding instances. REMOVE: indicates reducing instances. SET: indicates setting the number of instances to a specified value.
  job_records	Array of job_records objects	Specifies the tasks contained in a scaling action based on an AS policy. For details, see Table 4.
  meta_data	meta_data object	Provides additional information. For details, see Table 5.

  Table 4 job_records field description

  Parameter	Type	Description
  job_name	String	Specifies the task name.
  record_type	String	Specifies the record type. API: API calling type MEG: message type
  record_time	String	Specifies the record time.
  request	String	Specifies the request body. This parameter is valid only if record_type is set to API.
  response	String	Specifies the response body. This parameter is valid only if record_type is set to API.
  code	String	Specifies the returned code. This parameter is valid only if record_type is set to API.
  message	String	Specifies the message. This parameter is valid only if record_type is set to MEG.
  job_status	String	Specifies the execution status of the task. SUCCESS: The task is successfully executed. FAIL: The task failed to be executed.

  Table 5 meta_data field description

  Parameter	Type	Description
  metadata_bandwidth_share_type	String	Specifies the bandwidth sharing type in the bandwidth scaling policy.
  metadata_eip_id	String	Specifies the EIP ID for the bandwidth in the bandwidth scaling policy.
  metadataeip_address	String	Specifies the EIP for the bandwidth in the bandwidth scaling policy.
