Re: [SR-Users] xhttp_prom - Adding new metrics for dispatcher list to monitor SIP trunk availability

[Henning Westerholt]

Hello,

It should be possible to use e.g. a timer route to periodically fetch the 
status from localhost with RPC commands and to feed this into the counters 
etc.. from xhttp_prom.

But the easier way is probably just to use an external collector.

Cheers,

Henning

Subject: [SR-Users] xhttp_prom - Adding new metrics for dispatcher list to 
monitor SIP trunk availability

Hi Guys,

We are running kamailio 5.3 in our dev environment with a view to using the 
xhttp_prom module, so that we can monitor using prometheous.

It works fine in terms of getting all the internal stats and groups, however is 
it possible to grab the dispatcher.list output/stats using the module?

I know there is a collector that does this and provides the dispatcher gateway 
trunk status, but wondered if it could be implemented using xhttp_prom, or if 
external code would be required to grab the states using rpc etc?

Many thanks

Jon

Try to install debugging symbols for libmariadb and maybe there will be
more hints in the backtace of what it does internally, which can improve
troubleshooting by searching on the web for similar cases.

And, as I said in previous email, try to investigate the status of mysql
server with specific commands and tools, if you can find any out there.
From mysql client API, we set the query timeout options.

Otherwise, I haven't encountered such a situation yet to have any other
hint to share specific for it.

Maybe you can try to use IP sockets for connecting to mysql server, if
the connection is done over unixsocket file. In some older versions, it
was mentioned that timeout options may not work if not on an IP connection.

What you can also try, is to change the database table type. What do you
have now, MyISAM, InnoDB or something else?

To know better the ecosystem, what is the operation system and
mysq/mariadb versions?

Cheers,
Daniel

Thanks for reply Henning!

Yes I agree with the external collector, I am using it without issue will stick 
with it.

Accounting records are inserted without problems from other calls to the
same accounting table where the timer process tries to insert its
record but hangs.

Re: [SR-Users] unknown error messages

[Henning Westerholt]

Hello Juha,

the error message looks related to the TCP support in core. There was a 
mismatch in the internal TCP hash table, and it also could not send out a 
message on a (network) file descriptor. 

If you only saw it once it is probably not worth to dig that deep into it, 
might be also caused from some external factors.

Cheers,

Henning

Re: [SR-Users] Use topos module to hide contact in OPTIONS request

Hello,

the module aimed at supporting topology hiding for calls. Is the OPTIONS
part of a dialog or out-of-dialog (like a keepalive request)?

You simply need to follow the quick howto in tls module documentation (as i 
mentioned earlier) to generate client and server certificates. Then copy client 
cert along with CA to sip client, provide connection and authentication info 
and it should work fine.

For over simplified setup where you don't have client certificate or not sure 
how to configure one for any given sip client, you can disable 
"verify_certificate" option in tls module.

Hope this helps.

Are new records inserted in acc table? I think there are some
tools/commands for mysql to inspect the state a database table, check
acc table and missed_calls, if you also use this one.

It has appeared several times and may be related to json request.
Perhaps tcp connection is broken before K has delivered the result.

I did that already earlier when I reported about similar issue, which
made K totally unresponsive for a long period of time.  Nothing was
found from the backtrace.

DB type is InnoDB.

Latest stable Debian 10 that comes with mariadb 10.3.

On the positive side, so far the issue has not appeared after I
backported your db_cluster async insert patch to 5.3.  Perhaps there was
some issue in falling back to normal insert.
