Properties

For more information about each property, including constraints and valid values, see TargetTrackingScalingPolicyConfiguration in the Application Auto Scaling API Reference.

CustomizedMetricSpecification

A customized metric.

Required: No

Type: Application Auto Scaling ScalingPolicy CustomizedMetricSpecification

PredefinedMetricSpecification

A predefined metric.

Required: No

Type: Application Auto Scaling ScalingPolicy PredefinedMetricSpecification

Update requires: No interruption

ScaleInCooldown

The amount of time, in seconds, after a scale in activity completes before another scale in activity can start.

Required: No

Type: Integer

Update requires: No interruption

ScaleOutCooldown

The amount of time, in seconds, after a scale out activity completes before another scale out activity can start.

Required: No

Type: Integer
