Hello,

for UDP and SCTP traffic there is no buffer in Kamailio. The kernel does buffering and kamailio receives each datagram at once, process it and then gets the next one.

For tcp (tls), there is a read buffer in kamailio to parse as received, because it has to split the traffic in sip messages. But still the main buffer is in kernel.

In other words, kamailio doesn't have access to pending packets from the network. Ratelimit module works on the number of packets processed by kamailio (those already read from kernel buffer).

Cheers,
Daniel

Hi list,

Is there a way to survey the message buffer (iei the queue where arriving sip messages wait to be processed by worker threads) in Kamailio?

Is there a way to check the number of messages in this buffer? Additionally, is it possible to survey the number of messages by method (INVITE, BYE, etc.)?

I know that the ratelimit module (http://kamailio.org/docs/modules/stable/modules/ratelimit.html) shall access such buffers, but I do not see any variable accessible in the config offered by that module.

Am I missing sth or is there a way to do so?

Thanks

Alireza
