For statistics, there exists a LUA script you can use in HAProxy which aggregates the statistics of multiple processes. See http://www.arpalert.org/haproxy-scripts.html#stats As for socket commands, often you can circumenvent the whole issue by applying a multi-stage architecture where you have several "dumb" processes just terminating SSL and forwarding the plain-text traffic to a single HAProxy processes which performs all of the actual loadbalancing rules. With clever bind-process rules and by using send-proxy-v2 this is pretty workable. Often, there is then no need for close introspection of the frontend-processes anymore, nor is there a need to send socket commands to them since they always send all their traffic to haproy anyway Best, Holger
