This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::ApplicationAutoScaling::CustomizedMetricSpecification object:

  $service_obj->Method(Att1 => { Dimensions => $value, ..., Unit => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::ApplicationAutoScaling::CustomizedMetricSpecification object:

  $result = $service_obj->Method(...);


Represents a CloudWatch metric of your choosing for a target tracking scaling policy to use with Application Auto Scaling.

To create your customized metric specification:

  • Add values for each required parameter from CloudWatch. You can use an existing metric, or a new metric that you create. To use your own metric, you must first publish the metric to CloudWatch. For more information, see Publish Custom Metrics ( in the Amazon CloudWatch User Guide.

  • Choose a metric that changes proportionally with capacity. The value of the metric should increase or decrease in inverse proportion to the number of capacity units. That is, the value of the metric should decrease when capacity increases.

For more information about CloudWatch, see Amazon CloudWatch Concepts (


Dimensions => ArrayRef[Paws::ApplicationAutoScaling::MetricDimension]

  The dimensions of the metric.

Conditional: If you published your metric with dimensions, you must specify the same dimensions in your scaling policy.

REQUIRED MetricName => Str

  The name of the metric.

REQUIRED Namespace => Str

  The namespace of the metric.

REQUIRED Statistic => Str

  The statistic of the metric.

Unit => Str

  The unit of the metric.
