=head1 NAME

Paws::AutoScalingPlans::TargetTrackingConfiguration

=head1 USAGE

This class represents one of two things:

=head3 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::AutoScalingPlans::TargetTrackingConfiguration object:

  $service_obj->Method(Att1 => { CustomizedScalingMetricSpecification => $value, ..., TargetValue => $value  });

=head3 Results returned from an API call

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

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

=head1 DESCRIPTION

Describes a target tracking configuration to use with AWS Auto Scaling.
Used with ScalingInstruction and ScalingPolicy.

=head1 ATTRIBUTES


=head2 CustomizedScalingMetricSpecification => L<Paws::AutoScalingPlans::CustomizedScalingMetricSpecification>

A customized metric. You can specify either a predefined metric or a
customized metric.


=head2 DisableScaleIn => Bool

Indicates whether scale in by the target tracking scaling policy is
disabled. If the value is C<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.

The default value is C<false>.


=head2 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.


=head2 PredefinedScalingMetricSpecification => L<Paws::AutoScalingPlans::PredefinedScalingMetricSpecification>

A predefined metric. You can specify either a predefined metric or a
customized metric.


=head2 ScaleInCooldown => Int

The amount of time, in seconds, after a scale-in activity completes
before another scale-in activity can start. This property is not used
if the scalable resource is an Auto Scaling group.

With the I<scale-in cooldown period>, the intention is to scale in
conservatively to protect your applicationE<rsquo>s availability, so
scale-in activities are blocked until the cooldown period has expired.
However, if another alarm triggers a scale-out activity during the
scale-in cooldown period, Auto Scaling scales out the target
immediately. In this case, the scale-in cooldown period stops and
doesn't complete.


=head2 ScaleOutCooldown => Int

The amount of time, in seconds, to wait for a previous scale-out
activity to take effect. This property is not used if the scalable
resource is an Auto Scaling group.

With the I<scale-out cooldown period>, the intention is to continuously
(but not excessively) scale out. After Auto Scaling successfully scales
out using a target tracking scaling policy, it starts to calculate the
cooldown time. The scaling policy won't increase the desired capacity
again unless either a larger scale out is triggered or the cooldown
period ends.


=head2 B<REQUIRED> TargetValue => Num

The target value for the metric. Although this property accepts numbers
of type Double, it won't accept values that are either too small or too
large. Values must be in the range of -2^360 to 2^360.
