Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

TargetTrackingScalingPolicyConfiguration

Represents a target tracking scaling policy configuration to use with Application Auto Scaling.

For more information, see Target tracking scaling policies in the Application Auto Scaling User Guide.

Contents

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.

Note

If the scaling policy specifies the ALBRequestCountPerTarget predefined metric, specify the target utilization as the optimal average request count per target during any one-minute interval.

Type: Double

Required: Yes

CustomizedMetricSpecification

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

Type: CustomizedMetricSpecification object

Required: No

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.

Type: Boolean

Required: No

PredefinedMetricSpecification

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

Type: PredefinedMetricSpecification object

Required: No

ScaleInCooldown

The amount of time, in seconds, after a scale-in activity completes before another scale-in activity can start. For more information and for default values, see Define cooldown periods in the Application Auto Scaling User Guide.

Type: Integer

Required: No

ScaleOutCooldown

The amount of time, in seconds, to wait for a previous scale-out activity to take effect. For more information and for default values, see Define cooldown periods in the Application Auto Scaling User Guide.
