=head1 NAME

Paws::AutoScaling::StepAdjustment

=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::AutoScaling::StepAdjustment object:

  $service_obj->Method(Att1 => { MetricIntervalLowerBound => $value, ..., ScalingAdjustment => $value  });

=head3 Results returned from an API call

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

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

=head1 DESCRIPTION

Describes information used to create a step adjustment for a step
scaling policy.

For the following examples, suppose that you have an alarm with a
breach threshold of 50:

=over

=item *

To trigger the adjustment when the metric is greater than or equal to
50 and less than 60, specify a lower bound of 0 and an upper bound of
10.

=item *

To trigger the adjustment when the metric is greater than 40 and less
than or equal to 50, specify a lower bound of -10 and an upper bound of
0.

=back

There are a few rules for the step adjustments for your step policy:

=over

=item *

The ranges of your step adjustments can't overlap or have a gap.

=item *

At most, one step adjustment can have a null lower bound. If one step
adjustment has a negative lower bound, then there must be a step
adjustment with a null lower bound.

=item *

At most, one step adjustment can have a null upper bound. If one step
adjustment has a positive upper bound, then there must be a step
adjustment with a null upper bound.

=item *

The upper and lower bound can't be null in the same step adjustment.

=head1 ATTRIBUTES


=head2 MetricIntervalLowerBound => Num

The lower bound for the difference between the alarm threshold and the
CloudWatch metric. If the metric value is above the breach threshold,
the lower bound is inclusive (the metric must be greater than or equal
to the threshold plus the lower bound). Otherwise, it is exclusive (the
metric must be greater than the threshold plus the lower bound). A null
value indicates negative infinity.


=head2 MetricIntervalUpperBound => Num

The upper bound for the difference between the alarm threshold and the
CloudWatch metric. If the metric value is above the breach threshold,
the upper bound is exclusive (the metric must be less than the
threshold plus the upper bound). Otherwise, it is inclusive (the metric
must be less than or equal to the threshold plus the upper bound). A
null value indicates positive infinity.

The upper bound must be greater than the lower bound.


=head2 B<REQUIRED> ScalingAdjustment => Int

The amount by which to scale, based on the specified adjustment type. A
positive value adds to the current capacity while a negative number
removes from the current capacity.
