Represents a CloudWatch metric of your choosing for a target tracking scaling policy to use with Amazon EC2 Auto Scaling. To create your customized metric specification:

* Add values for each required property 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 (https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/publishingMetrics.html) 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 more information about the CloudWatch terminology below, see Amazon CloudWatch concepts (https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cloudwatch_concepts.html). Each individual service provides information about the metrics, namespace, and dimensions they use. For more information, see Amazon Web Services services that publish CloudWatch metrics (https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/aws-services-cloudwatch-metrics.html) in the Amazon CloudWatch User Guide.

}

The attributes for the instance types for a mixed instances policy. Amazon EC2 Auto Scaling uses your specified requirements to identify instance types. Then, it uses your On-Demand and Spot allocation strategies to launch instances from these instance types. When you specify multiple attributes, you get instance types that satisfy all of the specified attributes. If you specify multiple values for an attribute, you get instance types that satisfy any of the specified values. To limit the list of instance types from which Amazon EC2 Auto Scaling can identify matching instance types, you can use one of the following parameters, but not both in the same request:

* AllowedInstanceTypes - The instance types to include in the list. All other instance types are ignored, even if they match your specified attributes.

* ExcludedInstanceTypes - The instance types to exclude from the list, even if they match your specified attributes.

You must specify VCpuCount and MemoryMiB. All other attributes are optional. Any unspecified optional attribute is set to its default. For more information, see Creating an Auto Scaling group using attribute-based instance type selection (https://docs.aws.amazon.com/autoscaling/ec2/userguide/create-asg-instance-type-requirements.html) in the Amazon EC2 Auto Scaling User Guide. For help determining which instance types match your attributes before you apply them to your Auto Scaling group, see Preview instance types with specified attributes (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-fleet-attribute-based-instance-type-selection.html#ec2fleet-get-instance-types-from-instance-requirements) in the Amazon EC2 User Guide for Linux Instances.

	OnDemandPercentageAboveBaseCapacity *int32

	// The allocation strategy to apply to your Spot Instances when they are launched.

	// must be in the range of 1–20. Default: 2
	SpotInstancePools *int32

	// The maximum price per unit hour that you are willing to pay for a Spot Instance.
	// If your maximum price is lower than the Spot price for the instance types that
	// you selected, your Spot Instances are not launched. We do not recommend
	// specifying a maximum price because it can lead to increased interruptions. When
	// Spot Instances launch, you pay the current Spot price. To remove a maximum price
	// that you previously set, include the property but specify an empty string ("")

Use this structure to specify the launch templates and instance types (overrides) for a mixed instances policy.

type LaunchTemplateOverrides 

type LaunchTemplateOverrides struct {

	// The instance requirements. Amazon EC2 Auto Scaling uses your specified
	// requirements to identify instance types. Then, it uses your On-Demand and Spot
	// allocation strategies to launch instances from these instance types. You can
	// specify up to four separate sets of instance requirements per Auto Scaling
	// group. This is useful for provisioning instances from different Amazon Machine
	// Images (AMIs) in the same Auto Scaling group. To do this, create the AMIs and
	// create a new launch template for each AMI. Then, create a compatible set of
	// instance requirements for each launch template. If you specify
	// InstanceRequirements, you can't specify InstanceType.
	InstanceRequirements *InstanceRequirements

	// The instance type, such as m3.xlarge. You must specify an instance type that is
	// supported in your requested Region and Availability Zones. For more information,
	// see Instance types
	// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html) in the
	// Amazon Elastic Compute Cloud User Guide. You can specify up to 40 instance types
	// per Auto Scaling group.
	InstanceType *string

	// Provides a launch template for the specified instance type or set of instance
	// requirements. For example, some instance types might require a launch template
	// with a different AMI. If not provided, Amazon EC2 Auto Scaling uses the launch
	// template that's specified in the LaunchTemplate definition. For more
	// information, see Specifying a different launch template for an instance type
	// (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-mixed-instances-groups-launch-template-overrides.html)
	// in the Amazon EC2 Auto Scaling User Guide. You can specify up to 20 launch
	// templates per Auto Scaling group. The launch templates specified in the
	// overrides and in the LaunchTemplate definition count towards this limit.
	LaunchTemplateSpecification *LaunchTemplateSpecification

	// If you provide a list of instance types to use, you can specify the number of
	// capacity units provided by each instance type in terms of virtual CPUs, memory,
	// storage, throughput, or other relative performance characteristic. When a Spot
	// or On-Demand Instance is launched, the capacity units count toward the desired
	// capacity. Amazon EC2 Auto Scaling launches instances until the desired capacity
	// is totally fulfilled, even if this results in an overage. For example, if there
	// are two units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can
	// only launch an instance with a WeightedCapacity of five units, the instance is
	// launched, and the desired capacity is exceeded by three units. For more
	// information, see Configuring instance weighting for Amazon EC2 Auto Scaling
	// (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-mixed-instances-groups-instance-weighting.html)
	// in the Amazon EC2 Auto Scaling User Guide. Value must be in the range of 1–999.
	// If you specify a value for WeightedCapacity for one instance type, you must
	// specify a value for WeightedCapacity for all of them. Every Auto Scaling group
	// has three size parameters (DesiredCapacity, MaxSize, and MinSize). Usually, you
	// set these sizes based on a specific number of instances. However, if you
	// configure a mixed instances policy that defines weights for the instance types,
	// you must specify these sizes with the same units that you use for weighting
	// instances.
	WeightedCapacity *string
	// contains filtered or unexported fields
}

Use this structure to let Amazon EC2 Auto Scaling do the following when the Auto Scaling group has a mixed instances policy:

* Override the instance type that is specified in the launch template.

* Use multiple instance types.

Specify the instance types that you want, or define your instance requirements instead and let Amazon EC2 Auto Scaling provision the available instance types that meet your requirements. This can provide Amazon EC2 Auto Scaling with a larger selection of instance types to choose from when fulfilling Spot and On-Demand capacities. You can view which instance types are matched before you apply the instance requirements to your Auto Scaling group. After you define your instance requirements, you don't have to keep updating these settings to get new EC2 instance types automatically. Amazon EC2 Auto Scaling uses the instance requirements of the Auto Scaling group to determine whether a new EC2 instance type can be used.

	// contains filtered or unexported fields
}

This structure specifies the metrics and target utilization settings for a predictive scaling policy. You must specify either a metric pair, or a load metric and a scaling metric individually. Specifying a metric pair instead of individual metrics provides a simpler way to configure metrics for a scaling policy. You choose the metric pair, and the policy automatically knows the correct sum and average statistics to use for the load metric and the scaling metric. Example

* You create a predictive scaling policy and specify ALBRequestCount as the value for the metric pair and 1000.0 as the target value. For this type of metric, you must provide the metric dimension for the corresponding target group, so you also provide a resource label for the Application Load Balancer target group that is attached to your Auto Scaling group.

* The number of requests the target group receives per minute provides the load metric, and the request count averaged between the members of the target group provides the scaling metric. In CloudWatch, this refers to the RequestCount and RequestCountPerTarget metrics, respectively.

* For optimal use of predictive scaling, you adhere to the best practice of using a dynamic scaling policy to automatically scale between the minimum capacity and maximum capacity in response to real-time changes in resource utilization.

* Amazon EC2 Auto Scaling consumes data points for the load metric over the last 14 days and creates an hourly load forecast for predictive scaling. (A minimum of 24 hours of data is required.)

* After creating the load forecast, Amazon EC2 Auto Scaling determines when to reduce or increase the capacity of your Auto Scaling group in each hour of the forecast period so that the average number of requests received by each instance is as close to 1000 requests per minute as possible at all times.

Describes information used to create a step adjustment for a step scaling policy. 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.
