ApplicationAutoScaling

Client

class ApplicationAutoScaling.Client

A low-level client representing Application Auto Scaling:

client = session.create_client('application-autoscaling')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
delete_scaling_policy(**kwargs)

Deletes the specified scaling policy for an Application Auto Scaling scalable target.

Deleting a step scaling policy deletes the underlying alarm action, but does not delete the CloudWatch alarm associated with the scaling policy, even if it no longer has an associated action.

For more information, see Delete a Step Scaling Policy and Delete a Target Tracking Scaling Policy in the Application Auto Scaling User Guide .

            AdjustmentType is required if you are adding a new step scaling policy configuration.

          • StepAdjustments (list) --

            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.

            • (dict) --

              Represents a step adjustment for a StepScalingPolicyConfiguration . Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

              For the following examples, suppose that you have an alarm with a breach threshold of 50:

              • To trigger the adjustment when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10.
              • To trigger the adjustment when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0.

              There are a few rules for the step adjustments for your step policy:

              • The ranges of your step adjustments can't overlap or have a gap.
              • At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound.
              • At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound.
              • The upper and lower bound can't be null in the same step adjustment.
              • MetricIntervalLowerBound (float) --

                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.

              • MetricIntervalUpperBound (float) --

                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.

              • ScalingAdjustment (integer) --

                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.

          • MinAdjustmentMagnitude (integer) --

            The minimum value to scale by when scaling by percentages. 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.

            Valid only if the adjustment type is PercentChangeInCapacity .

          • Cooldown (integer) --

            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. 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
            • Amazon SageMaker endpoint variants
            • Custom resources

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

            • DynamoDB tables
            • DynamoDB global secondary indexes
            • Amazon Comprehend document classification endpoints
            • Lambda provisioned concurrency
            • Amazon Keyspaces tables
          • MetricAggregationType (string) --

            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 .

        • TargetTrackingScalingPolicyConfiguration (dict) --

          A target tracking scaling policy.

          • TargetValue (float) --

            The target value for the metric. The range is 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2).

          • PredefinedMetricSpecification (dict) --

            A predefined metric. You can specify either a predefined metric or a customized metric.

            • PredefinedMetricType (string) --

              The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleet requests and ECS services.

            • ResourceLabel (string) --

              Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Spot Fleet request or ECS service.

              Elastic Load Balancing sends data about your load balancers to Amazon CloudWatch. CloudWatch collects the data and specifies the format to use to access the data. The format is app/<load-balancer-name>/<load-balancer-id>/targetgroup/<target-group-name>/<target-group-id>, where:

              • app/<load-balancer-name>/<load-balancer-id> is the final portion of the load balancer ARN
              • targetgroup/<target-group-name>/<target-group-id> is the final portion of the target group ARN.

              To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

          • ScaleOutCooldown (integer) --

            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. While the scale-out 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.

          • ScaleInCooldown (integer) --

            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.

Returns
The specified waiter object.
Return type
botocore.waiter.Waiter
put_scaling_policy(**kwargs)

Creates or updates a scaling policy for an Application Auto Scaling scalable target.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scaling policy applies to the scalable target identified by those three attributes. You cannot create a scaling policy until you have registered the resource as a scalable target.

Multiple scaling policies can be in force at the same time for the same scalable target. You can have one or more target tracking scaling policies, one or more step scaling policies, or both. However, there is a chance that multiple policies could conflict, instructing the scalable target to scale out or in at the same time. Application Auto Scaling gives precedence to the policy that provides the largest capacity for both scale out and scale in. For example, if one policy increases capacity by 3, another policy increases capacity by 200 percent, and the current capacity is 10, Application Auto Scaling uses the policy with the highest calculated capacity (200% of 10 = 20) and scales out to 30.

We recommend caution, however, when using target tracking scaling policies with step scaling policies because conflicts between these policies can cause undesirable behavior. For example, if the step scaling policy initiates a scale-in activity before the target tracking policy is ready to scale in, the scale-in activity will not be blocked. After the scale-in activity completes, the target tracking policy could instruct the scalable target to scale out again.

For more information, see Target Tracking Scaling Policies and Step Scaling Policies in the Application Auto Scaling User Guide .

Note

If a scalable target is deregistered, the scalable target is no longer available to execute scaling policies. Any scaling policies that were specified for the scalable target are deleted.

    For more information, see Target Tracking Scaling Policies and Step Scaling Policies in the Application Auto Scaling User Guide .

  • StepScalingPolicyConfiguration (dict) --

    A step scaling policy.

    This parameter is required if you are creating a policy and the policy type is StepScaling .

    • AdjustmentType (string) --

      Specifies whether the ScalingAdjustment value in a StepAdjustment is an absolute number or a percentage of the current capacity.

      AdjustmentType is required if you are adding a new step scaling policy configuration.
    • StepAdjustments (list) --

      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.

      • (dict) --

        Represents a step adjustment for a StepScalingPolicyConfiguration . Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

        For the following examples, suppose that you have an alarm with a breach threshold of 50:

        • To trigger the adjustment when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10.
        • To trigger the adjustment when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0.

        There are a few rules for the step adjustments for your step policy:

        • The ranges of your step adjustments can't overlap or have a gap.
        • At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound.
        • At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound.
        • The upper and lower bound can't be null in the same step adjustment.
        • MetricIntervalLowerBound (float) --

          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.

        • MetricIntervalUpperBound (float) --

          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.

        • ScalingAdjustment (integer) -- [REQUIRED]

          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.

    • MinAdjustmentMagnitude (integer) --

      The minimum value to scale by when scaling by percentages. 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.

      Valid only if the adjustment type is PercentChangeInCapacity .

    • Cooldown (integer) --

      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. 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
      • Amazon SageMaker endpoint variants
      • Custom resources

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

      • DynamoDB tables
      • DynamoDB global secondary indexes
      • Amazon Comprehend document classification endpoints
      • Lambda provisioned concurrency
      • Amazon Keyspaces tables
    • MetricAggregationType (string) --

      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 .

  • TargetTrackingScalingPolicyConfiguration (dict) --

    A target tracking scaling policy. Includes support for predefined or customized metrics.

    This parameter is required if you are creating a policy and the policy type is TargetTrackingScaling .

    • TargetValue (float) -- [REQUIRED]

      The target value for the metric. The range is 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2).

        The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleet requests and ECS services.

      • ResourceLabel (string) --

        Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Spot Fleet request or ECS service.

        Elastic Load Balancing sends data about your load balancers to Amazon CloudWatch. CloudWatch collects the data and specifies the format to use to access the data. The format is app/<load-balancer-name>/<load-balancer-id>/targetgroup/<target-group-name>/<target-group-id>, where:

        • app/<load-balancer-name>/<load-balancer-id> is the final portion of the load balancer ARN
        • targetgroup/<target-group-name>/<target-group-id> is the final portion of the target group ARN.

        To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

            The value of the dimension.

      • Statistic (string) -- [REQUIRED]

        The statistic of the metric.

      • Unit (string) --

        The unit of the metric.

    • ScaleOutCooldown (integer) --

      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. While the scale-out 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:

      • ECS services
      • Spot Fleet requests
      • EMR clusters
      • AppStream 2.0 fleets
      • Aurora DB clusters
      • Amazon SageMaker endpoint variants
      • Custom resources

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

      • DynamoDB tables
      • DynamoDB global secondary indexes
      • Amazon Comprehend document classification endpoints
      • Lambda provisioned concurrency
      • Amazon Keyspaces tables
    • ScaleInCooldown (integer) --

      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.

      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
      • Amazon SageMaker endpoint variants
      • Custom resources

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

      • DynamoDB tables
      • DynamoDB global secondary indexes
      • Amazon Comprehend document classification endpoints
      • Lambda provisioned concurrency
      • Amazon Keyspaces tables
    • DisableScaleIn (boolean) --

      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 .

put_scheduled_action(**kwargs)

Creates or updates a scheduled action for an Application Auto Scaling scalable target.

Each scalable target is identified by a service namespace, resource ID, and scalable dimension. A scheduled action applies to the scalable target identified by those three attributes. You cannot create a scheduled action until you have registered the resource as a scalable target.

When start and end times are specified with a recurring schedule using a cron expression or rates, they form the boundaries of when the recurring action starts and stops.

To update a scheduled action, specify the parameters that you want to change. If you don't specify start and end times, the old values are deleted.

For more information, see Scheduled Scaling in the Application Auto Scaling User Guide .

Note

If a scalable target is deregistered, the scalable target is no longer available to run scheduled actions. Any scheduled actions that were specified for the scalable target are deleted.

register_scalable_target(**kwargs)

Registers or updates a scalable target.

A scalable target is a resource that Application Auto Scaling can scale out and scale in. Scalable targets are uniquely identified by the combination of resource ID, scalable dimension, and namespace.

When you register a new scalable target, you must specify values for minimum and maximum capacity. Application Auto Scaling scaling policies will not scale capacity to values that are outside of this range.

After you register a scalable target, you do not need to register it again to use other Application Auto Scaling operations. To see which resources have been registered, use DescribeScalableTargets . You can also view the scaling policies for a service namespace by using DescribeScalableTargets . If you no longer need a scalable target, you can deregister it by using DeregisterScalableTarget .

To update a scalable target, specify the parameters that you want to change. Include the parameters that identify the scalable target: resource ID, scalable dimension, and namespace. Any parameters that you don't specify are not changed by this update request.

          • StepAdjustments (list) --

            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.

            • (dict) --

              Represents a step adjustment for a StepScalingPolicyConfiguration . Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

              For the following examples, suppose that you have an alarm with a breach threshold of 50:

              • To trigger the adjustment when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10.
              • To trigger the adjustment when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0.

              There are a few rules for the step adjustments for your step policy:

              • The ranges of your step adjustments can't overlap or have a gap.
              • At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound.
              • At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound.
              • The upper and lower bound can't be null in the same step adjustment.
              • MetricIntervalLowerBound (float) --

                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.

              • MetricIntervalUpperBound (float) --

                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.

              • ScalingAdjustment (integer) --

                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.

          • MinAdjustmentMagnitude (integer) --

            The minimum value to scale by when scaling by percentages. 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.

            Valid only if the adjustment type is PercentChangeInCapacity .

          • Cooldown (integer) --

            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. 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
            • Amazon SageMaker endpoint variants
            • Custom resources

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

            • DynamoDB tables
            • DynamoDB global secondary indexes
            • Amazon Comprehend document classification endpoints
            • Lambda provisioned concurrency
            • Amazon Keyspaces tables
          • MetricAggregationType (string) --

            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 .

        • TargetTrackingScalingPolicyConfiguration (dict) --

          A target tracking scaling policy.

          • TargetValue (float) --

            The target value for the metric. The range is 8.515920e-109 to 1.174271e+108 (Base 10) or 2e-360 to 2e360 (Base 2).

          • PredefinedMetricSpecification (dict) --

            A predefined metric. You can specify either a predefined metric or a customized metric.

            • PredefinedMetricType (string) --

              The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleet requests and ECS services.

            • ResourceLabel (string) --

              Identifies the resource associated with the metric type. You can't specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Spot Fleet request or ECS service.

              Elastic Load Balancing sends data about your load balancers to Amazon CloudWatch. CloudWatch collects the data and specifies the format to use to access the data. The format is app/<load-balancer-name>/<load-balancer-id>/targetgroup/<target-group-name>/<target-group-id>, where:

              • app/<load-balancer-name>/<load-balancer-id> is the final portion of the load balancer ARN
              • targetgroup/<target-group-name>/<target-group-id> is the final portion of the target group ARN.

              To find the ARN for an Application Load Balancer, use the DescribeLoadBalancers API operation. To find the ARN for the target group, use the DescribeTargetGroups API operation.

          • CustomizedMetricSpecification (dict) --

            • Unit (string) --

              The unit of the metric.

          • ScaleOutCooldown (integer) --

            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. While the scale-out 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:

            • ECS services
            • Spot Fleet requests
            • EMR clusters
            • AppStream 2.0 fleets
            • Aurora DB clusters
            • Amazon SageMaker endpoint variants
            • Custom resources

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

            • DynamoDB tables
            • DynamoDB global secondary indexes
            • Amazon Comprehend document classification endpoints
            • Lambda provisioned concurrency
            • Amazon Keyspaces tables
          • ScaleInCooldown (integer) --

            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.

            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
            • Amazon SageMaker endpoint variants
            • Custom resources

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

            • DynamoDB tables
            • DynamoDB global secondary indexes
            • Amazon Comprehend document classification endpoints
            • Lambda provisioned concurrency
            • Amazon Keyspaces tables
          • DisableScaleIn (boolean) --

            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 .

        • Alarms (list) --

          The CloudWatch alarms associated with the scaling policy.

          • (dict) --

            Represents a CloudWatch alarm associated with a scaling policy.

            • AlarmName (string) --

              The name of the alarm.

            • AlarmARN (string) --

              The Amazon Resource Name (ARN) of the alarm.

        • CreationTime (datetime) --

          The Unix timestamp for when the scaling policy was created.
