[OpenSIPS-Users] Can load balancer show total number of call for a gateway

Fri Sep 7 18:56:35 CEST 2012

Hi,

Didn't understand you clearly.

When you define a size i.e calls=100 per gateway and you send a call from
opensips to that gateway its load becomes 1, and capacity obviously becomes
calls=99. Now, When you gateway sends call back and you increment its call
count variable $avp(IC_GW1) to 1 AND immediately resize the capacity like
calls = calls - 1; The capacity of your gateway become calls=98.

On hangup of that Incoming call from gateway you resize the capacity back.

Using Dialog module profiling you can do it easily.

And as per my understanding of your question this is what you wanted. I am
not sure if there is any clean way of doing this w/o going into the
load_balancer module code and editing it as per your requirement which will
be something like : Link the load_balancer module with the dialog module.
Create a modparam like "gw_incoming_call_monitor"= 1 | 0. if its set to 1,
internally tell dialog module to count the active incoming calls of each
load-balancer gateway and adjust the gateway's "load". I don't think this
is much of a big task.

Do spare me sir if you didn't like it.

Thanks,
Sammy
