Querying All AS Policies (V2)

Function

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

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

URI

GET /autoscaling-api/v2/{project_id}/scaling_policy

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.

**Table 1** Parameter description
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.
scaling_resource_id	No	String	Specifies the scaling resource ID.
scaling_resource_type	No	String	Specifies the scaling resource type. AS group: SCALING_GROUP Bandwidth: BANDWIDTH
scaling_policy_name	No	String	Specifies the AS policy name. Supports fuzzy search.
scaling_policy_id	No	String	Specifies the AS policy ID.
scaling_policy_type	No	String	Specifies the AS policy type. ALARM: alarm policy SCHEDULED: scheduled policy RECURRENCE: periodic policy
start_number	No	Integer	Specifies the start line number. The default value is 0. The minimum parameter value is 0.
limit	No	Integer	Specifies the number of query records. The default value is 20. The value ranges from 0 to 100.
sort_by	No	String	Specifies the sorting method. POLICY_NAME: AS policies are sorted by name. TRIGGER_CONDITION: AS policies are sorted by trigger condition. For example, in ascending order, alarm policies are first, and others are sorted in ascending order based on the latest triggering time. CREATE_TIME: AS policies are sorted based on the creation time.
order	No	String	Specifies the sorting order. ASC: ascending order DESC: descending order
alarm_id	No	String	Specifies the alarm rule ID.

Response parameters

**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_policies	Array of scaling_policies objects	Specifies AS policies. For details, see Table 3.

**Table 3** **scaling_policies** field description
Parameter	Type	Description
scaling_policy_name	String	Specifies the AS policy name.
scaling_policy_id	String	Specifies the AS policy ID.
scaling_resource_id	String	Specifies the scaling resource ID.
scaling_resource_type	String	Specifies the scaling resource type. AS group: SCALING_GROUP Bandwidth: BANDWIDTH
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	scheduled_policy object	Specifies the periodic or scheduled AS policy. For details, see Table 4.
scaling_policy_action	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	meta_data object	Provides additional information. For details, see Table 6.
description	String	Specifies the AS policy description.

**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 number of instances to be operated.
