Querying Details of an AS Policy (V2)

Function

This API is used to query details about a specified AS policy by policy ID.

The difference between the V2 and V1 APIs for querying details of an AS policy is that V2 contains scaling resource types in response messages.

**Table 1** Parameter description
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.

Response Message

Response parameters

**Table 2** Response parameters
Parameter	Type	Description
scaling_policy	Object	Specifies details about the AS policy. For details, see Table 3.

**Table 3** **scaling_policy** field description
Parameter	Type	Description
scaling_resource_id	String	Specifies the scaling resource ID.
scaling_resource_type	String	Specifies the scaling resource type. AS group: SCALING_GROUP Bandwidth: BANDWIDTH
scaling_policy_name	String	Specifies the AS policy name. Supports fuzzy search.
scaling_policy_id	String	Specifies the AS policy ID.
policy_status	String	Specifies the AS policy status. INSERVICE: The AS policy is enabled. PAUSED: The AS policy is disabled. EXECUTING: The AS policy is being executed.
scaling_policy_type	String	Specifies the AS policy type. ALARM: indicates that the scaling action is triggered by an alarm. A value is returned for alarm_id, and no value is returned for scheduled_policy. SCHEDULED: indicates that the scaling action is triggered as scheduled. A value is returned for scheduled_policy, and no value is returned for alarm_id, recurrence_type, recurrence_value, start_time, or end_time. RECURRENCE: indicates that the scaling action is triggered periodically. Values are returned for scheduled_policy, recurrence_type, recurrence_value, start_time, and end_time, and no value is returned for alarm_id.
alarm_id	String	Specifies the alarm ID.
scheduled_policy	Object	Specifies the periodic or scheduled AS policy. For details, see Table 4.
scaling_policy_action	Object	Specifies the scaling action of the AS policy. For details, see Table 5.
cool_down_time	Integer	Specifies the cooldown period (s).
create_time	String	Specifies the time when an AS policy was created. The time format complies with UTC.
meta_data	Object	Provides additional information. For details, see Table 6.

**Table 4** **scheduled_policy** field description
Parameter	Type	Description
launch_time	String	Specifies the time when the scaling action is triggered. The time format complies with UTC. If scaling_policy_type is set to SCHEDULED, the time format is YYYY-MM-DDThh:mmZ. If scaling_policy_type is set to RECURRENCE, the time format is hh:mm.
recurrence_type	String	Specifies the type of a periodically triggered scaling action. Daily: indicates that the scaling action is triggered once a day. Weekly: indicates that the scaling action is triggered once a week. Monthly: indicates that the scaling action is triggered once a month.
recurrence_value	String	Specifies the frequency at which scaling actions are triggered. If recurrence_type is set to Daily, the value is null, indicating that the scaling action is triggered once a day. If recurrence_type is set to Weekly, the value ranges from 1 (Sunday) to 7 (Saturday). The digits refer to dates in each week and separated by a comma, such as 1,3,5. If recurrence_type is set to Monthly, the value ranges from 1 to 31. The digits refer to the dates in each month and separated by a comma, such as 1,10,13,28.
start_time	String	Specifies the start time of the scaling action triggered periodically. The time format complies with UTC. The time format is YYYY-MM-DDThh:mmZ.
end_time	String	Specifies the end time of the scaling action triggered periodically. The time format complies with UTC. The time format is YYYY-MM-DDThh:mmZ.

**Table 5** **scaling_policy_action** field description
Parameter	Type	Description
operation	String	Specifies the scaling action. ADD: indicates adding instances. REDUCE: indicates reducing instances. SET: indicates setting the number of instances to a specified value.
size	Integer	Specifies the operation size.
percentage	Integer	Specifies the percentage of instances to be operated.
limits	Integer	Specifies the operation restrictions.

**Table 6** **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.
metadata_eip_address	String	Specifies the EIP for the bandwidth in the bandwidth scaling policy.
