// This API operation is superseded by DescribeTrafficSources , which can describe
// multiple traffic sources types. We recommend using DetachTrafficSources to
// simplify how you manage traffic sources. However, we continue to support
// DescribeLoadBalancerTargetGroups . You can use both the original
// DescribeLoadBalancerTargetGroups API operation and DescribeTrafficSources on
// the same Auto Scaling group. Gets information about the Elastic Load Balancing
// target groups for the specified Auto Scaling group. To determine the attachment
// status of the target group, use the State element in the response. When you
// attach a target group to an Auto Scaling group, the initial State value is
// Adding . The state transitions to Added after all Auto Scaling instances are
// registered with the target group. If Elastic Load Balancing health checks are
// enabled for the Auto Scaling group, the state transitions to InService after at
// least one Auto Scaling instance passes the health check. When the target group
// is in the InService state, Amazon EC2 Auto Scaling can terminate and replace
// any instances that are reported as unhealthy. If no registered instances pass
// the health checks, the target group doesn't enter the InService state. Target
// groups also have an InService state if you attach them in the
// CreateAutoScalingGroup API call. If your target group state is InService , but
// it is not working properly, check the scaling activities by calling
// DescribeScalingActivities and take any corrective actions necessary. For help
// with failed health checks, see Troubleshooting Amazon EC2 Auto Scaling: Health
// checks (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ts-as-healthchecks.html)
// in the Amazon EC2 Auto Scaling User Guide. For more information, see Use
// Elastic Load Balancing to distribute traffic across the instances in your Auto
// Scaling group (https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html)
// in the Amazon EC2 Auto Scaling User Guide. You can use this operation to
// describe target groups that were attached by using
// AttachLoadBalancerTargetGroups , but not for target groups that were attached by
