Load balancing by custom queue length

Thanks Kevin. Can you expand on the two options a little please, in phrases that an F5 beginner might understand? I understand you're saying the monitoring and control can be done from different locations, but I don't understand the F5 well enough yet to work out what's technically best, and which would take less effort. We want to load balance across the dozens of windows servers based purely on the size of their queues, over a certain threshold we probably want to remove it from the load balancer completely.
