Hi All, I'm implementing the load_balancer module on a very busy system where thousands of calls may arrive in a matter of seconds. The module is configured to receive heartbeats every 1 second from many freeswitch servers, I have this set as a low value to try and keep OpenSIPs up to date with the real call load, as close to real time as possible.
All servers exist in a single group "channels" to keep the initial implementation simple. When I kick off the session I use lb_start(1, "channels", "rs") and if that destination fails I use lb_is_started() and lb_next() to select the next destination. With the high call rate I'm concerned that the load values acquired 1 second ago will be used for the entirety of the following second which would likely lead to a highly imbalanced load. If 1000 calls arrive in that second I need them spread evenly over the freeswitch servers which can only happen if OpenSIPs is counting each call as its allocated. My hope is that the module increments its counters each time a call is allocated to a destination; however I have been unable to isolate the line of code which performs this operation so I'm reaching out for confirmation. I can see the module adding the dialogs to profiles and that a separate lb_count_call() method is provided for counting calls but I'm unclear on the exact usage although it certainly encourages me that this counting is taking place somewhere.
