This page describes the parameters and results for the operations of the AWS Auto Scaling Plans (2018-01-06), and shows how to use the Aws\AutoScalingPlans\AutoScalingPlansClient object to call the described operations. This documentation is specific to the 2018-01-06 API version of the service.
Operation Summary
Each of the following operations can be created from a client using
$client->getCommand('CommandName')
, where "CommandName" is the
name of one of the following operations. Note: a command is a value that
encapsulates an operation and the parameters used to create an HTTP request.
You can also create and send a command immediately using the magic methods
available on a client object: $client->commandName(/* parameters */)
.
You can send the command asynchronously (returning a promise) by appending the
word "Async" to the operation name: $client->commandNameAsync(/* parameters */)
.

CustomizedLoadMetricSpecification
Description
Represents a CloudWatch metric of your choosing that can be used for predictive scaling.
For predictive scaling to work with a customized load metric specification, AWS Auto Scaling needs access to the Sum
and Average
statistics that CloudWatch computes from metric data.
When you choose a load metric, make sure that the required Sum
and Average
statistics for your metric are available in CloudWatch and that they provide relevant data for predictive scaling. The Sum
statistic must represent the total load on the resource, and the Average
statistic must represent the average load per capacity unit of the resource. For example, there is a metric that counts the number of requests processed by your Auto Scaling group. If the Sum
statistic represents the total request count processed by the group, then the Average
statistic for the specified metric must represent the average request count processed by each instance of the group.
If you publish your own metrics, you can aggregate the data points at a given interval and then publish the aggregated data points to CloudWatch. Before AWS Auto Scaling generates the forecast, it sums up all the metric data points that occurred within each hour to match the granularity period that is used in the forecast (60 minutes).
For information about terminology, available metrics, or how to publish new metrics, see Amazon CloudWatch Concepts in the Amazon CloudWatch User Guide.
After creating your scaling plan, you can use the AWS Auto Scaling console to visualize forecasts for the specified metric. For more information, see View Scaling Information for a Resource in the AWS Auto Scaling User Guide.

CustomizedScalingMetricSpecification
Description
Represents a CloudWatch metric of your choosing that can be used for dynamic scaling as part of a target tracking scaling policy.
To create your customized scaling metric specification:
-
Add values for each required parameter from CloudWatch. You can use an existing metric, or a new metric that you create. To use your own metric, you must first publish the metric to CloudWatch. For more information, see Publish Custom Metrics in the Amazon CloudWatch User Guide.
-
Choose a metric that changes proportionally with capacity. The value of the metric should increase or decrease in inverse proportion to the number of capacity units. That is, the value of the metric should decrease when capacity increases.
For information about terminology, available metrics, or how to publish new metrics, see Amazon CloudWatch Concepts in the Amazon CloudWatch User Guide.

AWS Auto Scaling creates target tracking scaling policies based on the scaling instructions. Target tracking scaling policies adjust the capacity of your scalable resource as required to maintain resource utilization at the target value that you specified.
AWS Auto Scaling also configures predictive scaling for your Amazon EC2 Auto Scaling groups using a subset of parameters, including the load metric, the scaling metric, the target value for the scaling metric, the predictive scaling mode (forecast and scale or forecast only), and the desired behavior when the forecast capacity exceeds the maximum capacity of the resource. With predictive scaling, AWS Auto Scaling generates forecasts with traffic predictions for the two days ahead and schedules scaling actions that proactively add and remove resource capacity to match the forecast.
We recommend waiting a minimum of 24 hours after creating an Auto Scaling group to configure predictive scaling. At minimum, there must be 24 hours of historical data to generate a forecast. For more information, see Best Practices for AWS Auto Scaling in the AWS Auto Scaling User Guide.
Members
- CustomizedLoadMetricSpecification
-
- Type: CustomizedLoadMetricSpecification structure
The customized load metric to use for predictive scaling. This parameter or a PredefinedLoadMetricSpecification is required when configuring predictive scaling, and cannot be used otherwise.
- DisableDynamicScaling
-
- Type: boolean
Controls whether dynamic scaling by AWS Auto Scaling is disabled. When dynamic scaling is enabled, AWS Auto Scaling creates target tracking scaling policies based on the specified target tracking configurations.
The default is enabled (
false
). - MaxCapacity
-
- Required: Yes
- Type: int

- PredictiveScalingMaxCapacityBehavior
-
- Type: string
Defines the behavior that should be applied if the forecast capacity approaches or exceeds the maximum capacity specified for the resource. The default value is
SetForecastCapacityToMaxCapacity
.The following are possible values:
-
SetForecastCapacityToMaxCapacity
- AWS Auto Scaling cannot scale resource capacity higher than the maximum capacity. The maximum capacity is enforced as a hard limit. -
SetMaxCapacityToForecastCapacity
- AWS Auto Scaling may scale resource capacity higher than the maximum capacity to equal but not exceed forecast capacity. -
SetMaxCapacityAboveForecastCapacity
- AWS Auto Scaling may scale resource capacity higher than the maximum capacity by a specified buffer value. The intention is to give the target tracking scaling policy extra capacity if unexpected traffic occurs.
Only valid when configuring predictive scaling.
- PredictiveScalingMaxCapacityBuffer
-
- Type: int
The size of the capacity buffer to use when the forecast capacity is close to or exceeds the maximum capacity. The value is specified as a percentage relative to the forecast capacity. For example, if the buffer is 10, this means a 10 percent buffer, such that if the forecast capacity is 50, and the maximum capacity is 40, then the effective maximum capacity is 55.
Only valid when configuring predictive scaling. Required if the PredictiveScalingMaxCapacityBehavior is set to
SetMaxCapacityAboveForecastCapacity
, and cannot be used otherwise.The range is 1-100.
- PredictiveScalingMode
-
- Type: string

The default value is
KeepExternalPolicies
. If the parameter is set toReplaceExternalPolicies
, any scaling policies that are external to AWS Auto Scaling are deleted and new target tracking scaling policies created.Only valid when configuring dynamic scaling.
Condition: The number of existing policies to be replaced must be less than or equal to 50. If there are more than 50 policies to be replaced, AWS Auto Scaling keeps all existing policies and does not create new ones.
- ScheduledActionBufferTime
-
- Type: int
The amount of time, in seconds, to buffer the run time of scheduled scaling actions when scaling out. For example, if the forecast says to add capacity at 10:00 AM, and the buffer time is 5 minutes, then the run time of the corresponding scheduled scaling action will be 9:55 AM. The intention is to give resources time to be provisioned. For example, it can take a few minutes to launch an EC2 instance. The actual amount of time required depends on several factors, such as the size of the instance and whether there are startup scripts to complete.
The value must be less than the forecast interval duration of 3600 seconds (60 minutes). The default is 300 seconds.

- Type: 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 doesn't remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking scaling policy can remove capacity from the scalable resource.The default value is
false
. - EstimatedInstanceWarmup
-
- Type: int
The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. This value is used only if the resource is an Auto Scaling group.
- PredefinedScalingMetricSpecification
-
- Type: PredefinedScalingMetricSpecification structure
A predefined metric. You can specify either a predefined metric or a customized metric.
- ScaleInCooldown
-
- Type: int
The amount of time, in seconds, after a scale-in activity completes before another scale-in activity can start. This property is not used if the scalable resource is an Auto Scaling group.
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, Auto Scaling scales out the target immediately. In this case, the scale-in cooldown period stops and doesn't complete.
- ScaleOutCooldown
-
- Type: int
The amount of time, in seconds, to wait for a previous scale-out activity to take effect. This property is not used if the scalable resource is an Auto Scaling group.
With the scale-out cooldown period, the intention is to continuously (but not excessively) scale out. After 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.
- TargetValue
-
- Required: Yes
- Type: double
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.
