    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: ModifyScalingPolicy.
    Version Yes String Common Params. The value used for this API: 2018-04-19.
    Region Yes String Common Params. For more information, please see the list of regions supported by the product.
    AutoScalingPolicyId Yes String Alarm policy ID.
    ScalingPolicyName No String Alarm policy name.
    AdjustmentType No String The method to adjust the desired capacity after the alarm is triggered. It’s only available when ScalingPolicyType is Simple. Valid values:
  • CHANGE_IN_CAPACITY: Increase or decrease the desired capacity
  • EXACT_CAPACITY: Adjust to the specified desired capacity
  • PERCENT_CHANGE_IN_CAPACITY: Adjust the desired capacity by percentage
    • AdjustmentValue No Integer The adjustment value for the expected number of instances after an alarm is triggered. It applies only to simple policies.
  • When AdjustmentType is CHANGE_IN_CAPACITY, a positive AdjustmentValue indicates an increase in the number of instances after the alarm is triggered, and a negative AdjustmentValue indicates a decrease in the number of instances after the alarm is triggered.
  • When AdjustmentType is EXACT_CAPACITY, the value of AdjustmentValue represents the expected number of instances after the alarm is triggered, which should be greater than or equal to 0.
  • When AdjustmentType is PERCENT_CHANGE_IN_CAPACITY, a positive AdjustmentValue indicates an increase in the number of instances by percentage after the alarm is triggered, and a negative AdjustmentValue indicates a decrease in the number of instances by percentage after the alarm is triggered. The unit is: %.
    		•
    Cooldown No Integer Cooldown period (in seconds). It’s only available when ScalingPolicyType is Simple.
    MetricAlarm No MetricAlarm Alarm monitoring metric. It’s only available when ScalingPolicyType is Simple.
    PredefinedMetricType No String Preset monitoring item. It’s only available when ScalingPolicyType is TARGET_TRACKING. Valid values:
  • ASG_AVG_CPU_UTILIZATION: Average CPU utilization
  • ASG_AVG_LAN_TRAFFIC_OUT: Average private bandwidth out
  • ASG_AVG_LAN_TRAFFIC_IN: Average private bandwidth in
  • ASG_AVG_WAN_TRAFFIC_OUT: Average public bandwidth out
  • ASG_AVG_WAN_TRAFFIC_IN: Average public bandwidth in
    		•
    TargetValue No Integer Target value. It’s only available when ScalingPolicyType is TARGET_TRACKING. Value ranges:
  • ASG_AVG_CPU_UTILIZATION (in %): [1, 100)
  • ASG_AVG_LAN_TRAFFIC_OUT (in Mbps): >0
  • ASG_AVG_LAN_TRAFFIC_IN (in Mbps): >0
  • ASG_AVG_WAN_TRAFFIC_OUT (in Mbps): >0
  • ASG_AVG_WAN_TRAFFIC_IN (in Mbps): >0
    		•
    EstimatedInstanceWarmup No Integer Instance warm-up period (in seconds). It’s only available when ScalingPolicyType is TARGET_TRACKING. Value range: 0-3600.
    DisableScaleIn No Boolean Whether to disable scale-in. It’s only available when ScalingPolicyType is TARGET_TRACKING. Valid values:
  • true: Scaling in is not allowed.
  • false: Allows both scale-out and scale-in
    		•
    NotificationUserGroupIds.N No Array of String This parameter is diused. Please use CreateNotificationConfiguration instead.
    Notification group ID, which is the set of user group IDs.

    3. Output Parameters
