=head1 NAME

Paws::CloudFormation::RollbackConfiguration

=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::CloudFormation::RollbackConfiguration object:

  $service_obj->Method(Att1 => { MonitoringTimeInMinutes => $value, ..., RollbackTriggers => $value  });

=head3 Results returned from an API call

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

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

=head1 DESCRIPTION

Structure containing the rollback triggers for AWS CloudFormation to
monitor during stack creation and updating operations, and for the
specified monitoring period afterwards.

Rollback triggers enable you to have AWS CloudFormation monitor the
state of your application during stack creation and updating, and to
roll back that operation if the application breaches the threshold of
any of the alarms you've specified. For more information, see Monitor
and Roll Back Stack Operations
(http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-rollback-triggers.html).

=head1 ATTRIBUTES


=head2 MonitoringTimeInMinutes => Int

The amount of time, in minutes, during which CloudFormation should
monitor all the rollback triggers after the stack creation or update
operation deploys all necessary resources.

The default is 0 minutes.

If you specify a monitoring period but do not specify any rollback
triggers, CloudFormation still waits the specified period of time
before cleaning up old resources after update operations. You can use
this monitoring period to perform any manual stack validation desired,
and manually cancel the stack creation or update (using
CancelUpdateStack
(https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_CancelUpdateStack.html),
for example) as necessary.

If you specify 0 for this parameter, CloudFormation still monitors the
specified rollback triggers during stack creation and update
operations. Then, for update operations, it begins disposing of old
resources immediately once the operation completes.


=head2 RollbackTriggers => ArrayRef[L<Paws::CloudFormation::RollbackTrigger>]

The triggers to monitor during stack creation or update actions.

By default, AWS CloudFormation saves the rollback triggers specified
for a stack and applies them to any subsequent update operations for
the stack, unless you specify otherwise. If you do specify rollback
triggers for this parameter, those triggers replace any list of
triggers previously specified for the stack. This means:

=over

=item *

To use the rollback triggers previously specified for this stack, if
any, don't specify this parameter.

=item *

To specify new or updated rollback triggers, you must specify I<all>
the triggers that you want used for this stack, even triggers you've
specifed before (for example, when creating the stack or during a
previous stack update). Any triggers that you don't include in the
updated list of triggers are no longer applied to the stack.

=item *

To remove all currently specified triggers, specify an empty list for
this parameter.

=back

If a specified trigger is missing, the entire stack operation fails and
is rolled back.
