Alternatively, you can specify one of the following to filter the results: the ARN of the load balancer, the names of one or more target groups, or the ARNs of one or more target groups.

To describe the targets for a target group, use DescribeTargetHealth. To describe the attributes of a target group, use DescribeTargetGroupAttributes.
