This cannot be done with a fixed configuration element. I believe a better way of \
doing this would be to have some sort of coordination mechanism whereby one LB in the \
LB cluster is elected as the coordinator, and that coordinator can become the primary \
or be responsible for issuing autoscaling commands. In the case of failure of the \
primary (coordinator), there will be another election and a new coordinator will be \
elected. We should be able to do this with Tribes, but may have to implement some \
missing parts. For more details on the theory see <a \
