Function¶
This API is used to modify a specified AS policy.
URI¶
PUT /autoscaling-api/v1/{project_id}/scaling_policy/{scaling_policy_id}
Parameter | Mandatory | Type | Description |
|---|---|---|---|
project_id | Yes | String | Specifies the project ID. |
scaling_policy_id | Yes | String | Specifies an AS policy ID. For details, see Querying AS Policies Bound to an AS Group. |

scaling_policy_type | No | String | Specifies the AS policy type.
|
alarm_id | No | String | Specifies the alarm rule ID. This parameter is mandatory when scaling_policy_type is set to ALARM. After this parameter is specified, the value of scheduled_policy does not take effect. After you modify an alarm policy, the system automatically adds an alarm triggering activity of the autoscaling type to the alarm_actions field in the alarm rule specified by the parameter value. You can obtain the parameter value by querying Cloud Eye alarm rules. |
scheduled_policy | No | scheduled_policy object | Specifies the periodic or scheduled AS policy. This parameter is mandatory when scaling_policy_type is set to SCHEDULED or RECURRENCE. After this parameter is specified, the value of alarm_id does not take effect. For details, see Table 3. |
scaling_policy_action | No | scaling_policy_action object | Specifies the scaling action of the AS policy. For details, see Table 4. |
cool_down_time | No | Integer | Specifies the cooldown period (in seconds). The value ranges from 0 to 86400. |
Parameter | Mandatory | Type | Description |
|---|---|---|---|
launch_time | Yes | String | Specifies the time when the scaling action is triggered. The time format complies with UTC.
|
recurrence_type | No | String | Specifies the periodic triggering type. This parameter is mandatory when scaling_policy_type is set to RECURRENCE.
|
recurrence_value | No | String | Specifies the day when a periodic scaling action is triggered. This parameter is mandatory when scaling_policy_type is set to RECURRENCE.
|
start_time | No | 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 | No | String | Specifies the end time of the scaling action triggered periodically. The time format complies with UTC. This parameter is mandatory when scaling_policy_type is set to RECURRENCE. When the scaling action is triggered periodically, the end time cannot be earlier than the current and start time. The time format is YYYY-MM-DDThh:mmZ. |
Parameter | Mandatory | Type | Description |
|---|---|---|---|
operation | No | String | Specifies the operation to be performed. The default operation is ADD.
|
instance_number | No | Integer | Specifies the number of instances to be operated. The default number is 1. The value range is as follows for a default quota:
Note Either instance_number or instance_percentage is required. |
instance_percentage | No | Integer | Specifies the percentage of instances to be operated. You can increase, decrease, or set the number of instances in an AS group to the specified percentage of the current number of instances. If operation is set to ADD, REMOVE or REDUCE, the value is an integer from 1 to 20000. If operation is set to SET, the value is an integer from 0 to 20000. If neither instance_number nor instance_percentage is specified, the number of instances to be operated is 1. Either instance_number or instance_percentage is required. |
