Hello,

there is a statistic value giving the active tcp connections (which include the tls connections) and then you can get the value via $stat(...) variable:

  - https://www.kamailio.org/wikidocs/cookbooks/5.7.x/pseudovariables/#statname-statistics

I don't recall right now if the name of the stat is with its group id or without, you have to try.

Cheers,
Daniel

Hello,

My plan is to reject new inbound requests if there is already a certain number of open connections on one Kamailio server. I could answer with a 503 and directly close the connection forcing the client to reconnect and the loadbalancer to send traffic to a different node on the next connect. It's just a last-resort measure to prevent Kamailio from running into the configured TCP connection limit (workarounding a poorly-implemented external load balancer).

Since I didn't find anything in the docs: Is there a pseudovariable containing the current number of open tcp/tls connections on this Kamailio? I can (and already do) query them via kamcmd or rpc, but can I access the variable from inside the routing script as well?

Regards,

Sebastian
