[sr-dev] Kamailio load stat

Hey Guys, Does anyone know of a stat that indicates load in Kamailio. Here I am specifically looking to see how loaded my children are, whether they be UDP, TCP or SCTP, etc. A cool stat would be something like in the last t seconds children were busy 95% of the time on average., etc. Having a look at the udp receover code we could just time the processing loop for each process. I'm sure this would be similar for TCP/SCTP. Any stats like this already exist? or should I go ahead? cheers Jason
