Properties

customizedScalingMetricSpecification CustomizedScalingMetricSpecification?
A customized metric. You can specify either a predefined metric or a customized metric.
final
disableScaleIn bool?
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.
final
estimatedInstanceWarmup 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.
final
hashCode int
The hash code for this object.
no setterinherited
predefinedScalingMetricSpecification PredefinedScalingMetricSpecification?
A predefined metric. You can specify either a predefined metric or a customized metric.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
scaleInCooldown int?
The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. This value is not used if the scalable resource is an Auto Scaling group.
final
scaleOutCooldown int?
The amount of time, in seconds, after a scale-out activity completes before another scale-out activity can start. This value is not used if the scalable resource is an Auto Scaling group.
final
targetValue double
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).
