       The following object methods are supported:

        InstanceId   -- The Instance ID of the instance attached to the load balancer
        State        -- Specifies the current status of the instance
        ReasonCode   -- Provides information about the cause of OutOfService instances.
                        Specifically, it indicates whether the cause is Elastic Load Balancing
                        or the instance behind the load balancer
