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::LifecycleHook object:

  $service_obj->Method(Att1 => { AutoScalingGroupName => $value, ..., RoleARN => $value  });

Results returned from an API call

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

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


Describes a lifecycle hook, which tells Auto Scaling that you want to perform an action when an instance launches or terminates. When you have a lifecycle hook in place, the Auto Scaling group will either:

  • Pause the instance after it launches, but before it is put into service

  • Pause the instance as it terminates, but before it is fully terminated

For more information, see Auto Scaling Pending State and Auto Scaling Terminating State in the Auto Scaling Developer Guide.


AutoScalingGroupName => Str

  The name of the Auto Scaling group for the lifecycle hook.

DefaultResult => Str

  Defines the action the Auto Scaling group should take when the
lifecycle hook timeout elapses or if an unexpected failure occurs. The
valid values are C<CONTINUE> and C<ABANDON>. The default value is

GlobalTimeout => Int

  The maximum time, in seconds, that an instance can remain in a
C<Pending:Wait> or C<Terminating:Wait> state. The default is 172800
seconds (48 hours).

HeartbeatTimeout => Int

  The maximum time, in seconds, that can elapse before the lifecycle hook
times out. The default is 3600 seconds (1 hour). When the lifecycle
hook times out, Auto Scaling performs the action defined in the
C<DefaultResult> parameter. You can prevent the lifecycle hook from
timing out by calling RecordLifecycleActionHeartbeat.

LifecycleHookName => Str

  The name of the lifecycle hook.

LifecycleTransition => Str

  The state of the EC2 instance to which you want to attach the lifecycle
hook. For a list of lifecycle hook types, see

NotificationMetadata => Str

  Additional information that you want to include any time Auto Scaling
sends a message to the notification target.

NotificationTargetARN => Str

  The ARN of the notification target that Auto Scaling uses to notify you
when an instance is in the transition state for the lifecycle hook.
This ARN target can be either an SQS queue or an SNS topic. The
notification message sent to the target includes the following:
  • Lifecycle action token

  • User account ID

  • Name of the Auto Scaling group

  • Lifecycle hook name

  • EC2 instance ID

  • Lifecycle transition

  • Notification metadata

RoleARN => Str

  The ARN of the IAM role that allows the Auto Scaling group to publish
to the specified notification target.
