Hello,
I am just curious what is a scenario or configuration which can cause that and therefore need for such monitoring.
The remote endpoints are not SIP endpoints? Are you monitoring async_workers?

Hello Alex,
indeed, this is easier to analyse with the usual system management tools.
Small addition, for TCP and TLS there is actually a distributor or main process inside Kamailio:
$ kamcmd ps |grep tcp |grep main 18439 tcp main process
$ netstat -nap |grep 5060 | grep 18439 tcp 0 0 116.203.XXX.XXX:5060 0.0.0.0:* LISTEN 18439/kamailio tcp 0 0 116.203.XXX.XXX:5060 0.0.0.0:* LISTEN 18439/kamailio tcp 0 0 127.0.0.1:5060 0.0.0.0:* LISTEN 18439/kamailio tcp6 0 0 2a01:4f8:XXXX:XXXX::5060 :::* LISTEN 18439/kamailio
Cheers,
Henning

It's hard for children to introspect on and report their own busy
status, and
there's no distributor/supervisor process that has that kind of awareness about the children[1].
`ss -nl` (or `netstat` equivalent) will show you, in the RecvQ column,
the
number of packets (UDP) or connections (TCP) that are stacked up and
going
unreplied by any child. This figure should be 0 or substantially 0 if
things are
going well.

[1] Notwithstanding the recent 6.x change that optionally adds such a process.

If TCP children are busy, Please correct me if I am wrong if the remote IP is not responding via
TCP
protocol, this leads to a timeout and this child is busy.
If many remote endpoints are not reachable via TCP this can lead to
the case
when half or more children are by timeout operations.
I think required to monitor how many children are busy. Is it possible to get such info using kamcmd utility, statistics
module, or
xprom module.
