API Reference (API Version 2011-01-01)

LoadBalancerTargetGroupState

Describes the state of a target group.

If you attach a target group to an existing Auto Scaling group, the initial state is Adding. The state transitions to Added after all Auto Scaling instances are registered with the target group. If ELB health checks are enabled, the state transitions to InService after at least one Auto Scaling instance passes the health check. If EC2 health checks are enabled instead, the target group remains in the Added state.
