NAME

Paws::AutoScaling::PredictiveScalingConfiguration

USAGE

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::AutoScaling::PredictiveScalingConfiguration object:

  $service_obj->Method(Att1 => { MaxCapacityBreachBehavior => $value, ..., SchedulingBufferTime => $value  });

Results returned from an API call

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

  $result = $service_obj->Method(...);
  $result->Att1->MaxCapacityBreachBehavior

DESCRIPTION

Represents a predictive scaling policy configuration to use with Amazon EC2 Auto Scaling.

ATTRIBUTES

MaxCapacityBreachBehavior => Str

Defines the behavior that should be applied if the forecast capacity approaches or exceeds the maximum capacity of the Auto Scaling group. Defaults to "HonorMaxCapacity" if not specified.

The following are possible values:

"HonorMaxCapacity" - Amazon EC2 Auto Scaling cannot scale out capacity higher than the maximum capacity. The maximum capacity is enforced as a hard limit.
"IncreaseMaxCapacity" - Amazon EC2 Auto Scaling can scale out capacity higher than the maximum capacity when the forecast capacity is close to or exceeds the maximum capacity. The upper limit is determined by the forecasted capacity and the value for "MaxCapacityBuffer".

MaxCapacityBuffer => Int

The size of the capacity buffer to use when the forecast capacity is close to or exceeds the maximum capacity. The value is specified as a percentage relative to the forecast capacity. For example, if the buffer is 10, this means a 10 percent buffer, such that if the forecast capacity is 50, and the maximum capacity is 40, then the effective maximum capacity is 55.

If set to 0, Amazon EC2 Auto Scaling may scale capacity higher than the maximum capacity to equal but not exceed forecast capacity.

Required if the "MaxCapacityBreachBehavior" property is set to "IncreaseMaxCapacity", and cannot be used otherwise.

REQUIRED MetricSpecifications => ArrayRef[Paws::AutoScaling::PredictiveScalingMetricSpecification]

This structure includes the metrics and target utilization to use for predictive scaling.

This is an array, but we currently only support a single metric specification. That is, you can specify a target value and a single metric pair, or a target value and one scaling metric and one load metric.

Mode => Str

The predictive scaling mode. Defaults to "ForecastOnly" if not specified.

SchedulingBufferTime => Int

The amount of time, in seconds, by which the instance launch time can be advanced. For example, the forecast says to add capacity at 10:00 AM, and you choose to pre-launch instances by 5 minutes. In that case, the instances will be launched at 9:55 AM. The intention is to give resources time to be provisioned. It can take a few minutes to launch an EC2 instance. The actual amount of time required depends on several factors, such as the size of the instance and whether there are startup scripts to complete.

The value must be less than the forecast interval duration of 3600 seconds (60 minutes). Defaults to 300 seconds if not specified.
