Profile: The type of farm profile, either HTTP or L4xNAT.
Virtual IP: The virtual IP address that receives traffic for the farm.
Virtual Port: The port that the load balancer uses to manage and distribute traffic to the farm.
Established Conns: The number of active connections to the farm. This does not necessarily mean one connection per connected client.
Pending Conns: The number of connections that are waiting to be served by the farm.
