Properties

CustomizedMetricSpecification

A customized metric.

object? CustomizedMetricSpecification { get; }

Property Value

object

Remarks

You must specify either a predefined metric or a customized metric.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-autoscaling-scalingpolicy-targettrackingconfiguration.html#cfn-autoscaling-scalingpolicy-targettrackingconfiguration-customizedmetricspecification

DisableScaleIn

Indicates whether scaling in by the target tracking scaling policy is disabled.

object? DisableScaleIn { get; }

Property Value

object

Remarks

If scaling in is disabled, the target tracking scaling policy doesn't remove instances from the Auto Scaling group. Otherwise, the target tracking scaling policy can remove instances from the Auto Scaling group. The default is false .

PredefinedMetricSpecification

A predefined metric.

object? PredefinedMetricSpecification { get; }

Property Value

object

Remarks

You must specify either a predefined metric or a customized metric.

Link: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-autoscaling-scalingpolicy-targettrackingconfiguration.html#cfn-autoscaling-scalingpolicy-targettrackingconfiguration-predefinedmetricspecification

TargetValue

The target value for the metric.

double TargetValue { get; }

Property Value

double

Remarks

Some metrics are based on a count instead of a percentage, such as the request count for an Application Load Balancer or the number of messages in an SQS queue. If the scaling policy specifies one of these metrics, specify the target utilization as the optimal average request or message count per instance during any one-minute interval.
