Date startTime
The date and time that the action is scheduled to begin, in UTC.
Date endTime
The date and time that the action is scheduled to end, in UTC.
ScalableTargetAction scalableTargetAction
The new minimum and maximum capacity. You can set both values or just one. At the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.
Date creationTime
The date and time that the scheduled action was created.
Double metricIntervalLowerBound
The lower bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the lower bound is inclusive (the metric must be greater than or equal to the threshold plus the lower bound). Otherwise, it is exclusive (the metric must be greater than the threshold plus the lower bound). A null value indicates negative infinity.
Double metricIntervalUpperBound
The upper bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the upper bound is exclusive (the metric must be less than the threshold plus the upper bound). Otherwise, it is inclusive (the metric must be less than or equal to the threshold plus the upper bound). A null value indicates positive infinity.
The upper bound must be greater than the lower bound.
Integer scalingAdjustment
The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity. For exact capacity, you must specify a positive value.
String adjustmentType
Specifies how the ScalingAdjustment value in a StepAdjustment is interpreted (for example, an absolute number or a percentage). The valid values are
ChangeInCapacity, ExactCapacity, and PercentChangeInCapacity.
AdjustmentType is required if you are adding a new step scaling policy configuration.
List<E> stepAdjustments
A set of adjustments that enable you to scale based on the size of the alarm breach.
At least one step adjustment is required if you are adding a new step scaling policy configuration.
Integer minAdjustmentMagnitude
The minimum value to scale by when the adjustment type is PercentChangeInCapacity. For example,
suppose that you create a step scaling policy to scale out an Amazon ECS service by 25 percent and you specify a
MinAdjustmentMagnitude of 2. If the service has 4 tasks and the scaling policy is performed, 25
percent of 4 is 1. However, because you specified a MinAdjustmentMagnitude of 2, Application Auto
Scaling scales out the service by 2 tasks.
Integer cooldown
The amount of time, in seconds, to wait for a previous scaling activity to take effect.
With scale-out policies, the intention is to continuously (but not excessively) scale out. After Application Auto Scaling successfully scales out using a step scaling policy, it starts to calculate the cooldown time. The scaling policy won't increase the desired capacity again unless either a larger scale out is triggered or the cooldown period ends. While the cooldown period is in effect, capacity added by the initiating scale-out activity is calculated as part of the desired capacity for the next scale-out activity. For example, when an alarm triggers a step scaling policy to increase the capacity by 2, the scaling activity completes successfully, and a cooldown period starts. If the alarm triggers again during the cooldown period but at a more aggressive step adjustment of 3, the previous increase of 2 is considered part of the current capacity. Therefore, only 1 is added to the capacity.
With scale-in policies, the intention is to scale in conservatively to protect your application’s availability, so scale-in activities are blocked until the cooldown period has expired. However, if another alarm triggers a scale-out activity during the cooldown period after a scale-in activity, Application Auto Scaling scales out the target immediately. In this case, the cooldown period for the scale-in activity stops and doesn't complete.
Application Auto Scaling provides a default value of 300 for the following scalable targets:
ECS services
Spot Fleet requests
EMR clusters
AppStream 2.0 fleets
Aurora DB clusters

Custom resources
For all other scalable targets, the default value is 0:

Lambda provisioned concurrency
Amazon Keyspaces tables
Amazon MSK broker storage
String metricAggregationType
The aggregation type for the CloudWatch metrics. Valid values are Minimum, Maximum, and
Average. If the aggregation type is null, the value is treated as Average.
Boolean dynamicScalingInSuspended
Whether scale in by a target tracking scaling policy or a step scaling policy is suspended. Set the value to
true if you don't want Application Auto Scaling to remove capacity when a scaling policy is
triggered. The default is false.
Boolean dynamicScalingOutSuspended
Whether scale out by a target tracking scaling policy or a step scaling policy is suspended. Set the value to
true if you don't want Application Auto Scaling to add capacity when a scaling policy is triggered.
The default is false.
Boolean scheduledScalingSuspended
Whether scheduled scaling is suspended. Set the value to true if you don't want Application Auto
Scaling to add or remove capacity by initiating scheduled actions. The default is false.
Double targetValue
The target value for the metric. Although this property accepts numbers of type Double, it won't accept values that are either too small or too large. Values must be in the range of -2^360 to 2^360. The value must be a valid number based on the choice of metric. For example, if the metric is CPU utilization, then the target value is a percent value that represents how much of the CPU can be used before scaling out.
PredefinedMetricSpecification predefinedMetricSpecification
A predefined metric. You can specify either a predefined metric or a customized metric.
CustomizedMetricSpecification customizedMetricSpecification
A customized metric. You can specify either a predefined metric or a customized metric.
Integer scaleOutCooldown
The amount of time, in seconds, to wait for a previous scale-out activity to take effect.
With the scale-out cooldown period, the intention is to continuously (but not excessively) scale out. After Application Auto Scaling successfully scales out using a target tracking scaling policy, it starts to calculate the cooldown time. The scaling policy won't increase the desired capacity again unless either a larger scale out is triggered or the cooldown period ends. While the cooldown period is in effect, the capacity added by the initiating scale-out activity is calculated as part of the desired capacity for the next scale-out activity.
Application Auto Scaling provides a default value of 300 for the following scalable targets:

Integer scaleInCooldown
The amount of time, in seconds, after a scale-in activity completes before another scale-in activity can start.
With the scale-in cooldown period, the intention is to scale in conservatively to protect your application’s availability, so scale-in activities are blocked until the cooldown period has expired. However, if another alarm triggers a scale-out activity during the scale-in cooldown period, Application Auto Scaling scales out the target immediately. In this case, the scale-in cooldown period stops and doesn't complete.

Boolean disableScaleIn
Indicates whether scale in by the target tracking scaling policy is disabled. If the value is true,
scale in is disabled and the target tracking scaling policy won't remove capacity from the scalable target.
Otherwise, scale in is enabled and the target tracking scaling policy can remove capacity from the scalable
target. The default value is false.
