AutoScalingTargetTrackingScalingPolicyConfigurationDescription

Represents the properties of a target tracking scaling policy.

Contents

Note

In the following list, the required parameters are described first.

TargetValue

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).

Type: Double

Required: Yes

DisableScaleIn

Indicates whether scale in by the target tracking policy is disabled. If the value is true, scale in is disabled and the target tracking policy won't remove capacity from the scalable resource. Otherwise, scale in is enabled and the target tracking policy can remove capacity from the scalable resource. The default value is false.

Type: Boolean

Required: No

ScaleInCooldown

The amount of time, in seconds, after a scale in activity completes before another scale in activity can start. The cooldown period is used to block subsequent scale in requests until it has expired. You should scale in conservatively to protect your application's availability. However, if another alarm triggers a scale out policy during the cooldown period after a scale-in, application autoscaling scales out your scalable target immediately.

Type: Integer

Required: No

ScaleOutCooldown

The amount of time, in seconds, after a scale out activity completes before another scale out activity can start. While the cooldown period is in effect, the capacity that has been added by the previous scale out event that initiated the cooldown is calculated as part of the desired capacity for the next scale out. You should continuously (but not excessively) scale out.

Type: Integer

Required: No
