    "LifecycleHooks": [
        {
            "GlobalTimeout": 3000,
            "HeartbeatTimeout": 30,
            "AutoScalingGroupName": "my-asg",
            "LifecycleHookName": "my-launch-hook",
            "DefaultResult": "ABANDON",
            "LifecycleTransition": "autoscaling:EC2_INSTANCE_LAUNCHING"
        },
        {
            "GlobalTimeout": 6000,
            "HeartbeatTimeout": 60,
            "AutoScalingGroupName": "my-asg",
            "LifecycleHookName": "my-termination-hook",
            "DefaultResult": "CONTINUE",
            "LifecycleTransition": "autoscaling:EC2_INSTANCE_TERMINATING"
        }
    ]
}
