Overview
Create or edit a scaling policy
Description
Create or edit a scaling policy. Once a policy has been called to be enforced, the scale-in or scale-out action is operated based on the set scaling policy.
Request Parameters
| Parameter | Required | Type | Restrictions | Description |
|---|---|---|---|---|
| policyName | Yes | String | Min : 1, Max : 255 | Policy name. The identifier of a scaling policy. The policy name belongs to a specific Auto Scaling Group, and the name cannot be duplicated within the same group. If there is no existing policy name within the selected Auto Scaling Group range when calling the api, create a new one. If there is the policy name created, change the details. Each Auto Scaling Group can have up to 10 policies. |
| autoScalingGroupName | Yes | String | Min : 1, Max : 255 | Name(Identifier) of Auto Scaling Group that a policy will be operated |
| adjustmentTypeCode | Yes | String | Min : 1, Max : 5 | Type code to control capacity of a group There are 3 valid codes as follows. (Applicable codes are written in the brackets.) * ChangeInCapacity(CHANG) : The value of capacity is changed into the assigned value. Equation) (new desired capacity) = (current actual capacity) + (scalingAdjustment of ChangeInCapacity type) * ExactCapacity(EXACT): The capacity is changed as much as the assigned percentage value. Equation) (new desired capacity) = (scalingAdjustment of ExactCapacity type) * PercentChangeInCapacity(PRCNT) : Capacity changes by the specified perecent value Equation) (new desired capacity) = (current actual capacity) + (current actual capacity) X (scalingAdjustment of PercentChangeInCapacity type) / 100 |
| scalingAdjustment | Yes | Integer | Min: -2147483647, Max : 2147483647 | Adjustment value of group capacity for a scaling If the adjustmentTypeCode value is ChangeInCapacity(CHANG) or PercentChangeInCapacity(PRCNT) type, i ) If scalingAdjustment is positive, then the capacity is increased and scale-out ii) If scalingAdjustment is negative, the capacity is reduced to scale-in The minimum value of scalingAdjustment of type PercentChangeInCapacity (PRCNT) is -100. |
| cooldown | No | Integer | Min : 0, Max : 2147483647 | Once a scaling action is over, ignore any alarm occurred during the cooldown period. |
| minAdjustmentStep | No | Integer | Min : 1, Max : 2147483647 | Minimum adjustment step It can only be assigned when the adjustmentTypeCode is PercentChangeInCapacity(PRCNT).(Therefore, the assignment is not necessary.) It cannot be specified under any other code types. When the changed value due to the scalingAdjustment is lower than the minAdjustmentStep under PercentChangeInCapacity(PRCNT) type, set the change value as the minAdjustmetStep. |
