Hello,<br>
<br>
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.<br>
<br>
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.<br>
<br>
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).<br>
<br>
Cheers,<br>

<div dir="ltr">Hi list,
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>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.)?</div>
<div><br>
</div>
<div><br>
</div>
<div>I know that the ratelimit module (<a href="http://kamailio.org/docs/modules/stable/modules/ratelimit.html" target="_blank">http://kamailio.org/docs/modules/stable/modules/ratelimit.html</a>)
shall access such buffers, but I do not see any variable
accessible in the config offered by that module.</div>
<div><br>
</div>
<div>Am I missing sth or is there a way to do so?</div>
<div><br>
</div>
<div>Thanks</div>
