Hi,

Thanks  all for your information.

Now this morning on live SIP Proxies, I have configured the /etc/systemd/journald.conf with :

RateLimitIntervalSec=0
RateLimitBurst=0

I have restarted the journald/rsyslog services. But few seconds later, the logging still stop again.

I have applied the other values suggested in the old article:

RateLimitBurst=1000000 in /etc/systemd/journald.conf

$imjournalRatelimitInterval 1 and $imjournalRatelimitBurst 500000 in /etc/rsyslog.conf

With the above values, I have new no more logs issues like reported in the article.

The above issue is a pure OS problem and I will probably open a ticket to RedHat.

Now back on my initial question related to journald.

On my SIP Proxies, journald is using about 10% of the CPU configured, which is very high when Kamailio used about 1%.

So I’m looking to replace the current mechanism to write log thru the standard openlog() and syslog() functions. I assume this is done using the ‘xlog’ module.

Do you think possible to change this by a mechanism to send log messages thru UDP to write the logs directly to rsyslog,

meaning to replace all the xlog calls in the kamailio.cfg script ?

Cordialement.

you need configure journald config file

/etc/systemd/journald.conf

[root@bcf-b ~]# grep RateLimit /etc/systemd/journald.conf
RateLimitIntervalSec=0
RateLimitBurst=0

Hello,

kamailio uses internally openlog() and syslog() functions from standard libc. It has not control of what the syslog daemon does, it is a matter of OS configuration, so what you mention might be the required configuration, not a workaround. Anyhow, maybe others can comment more.

There are many other cases when the OS has to be tuned to get desired behaviour, eg., increase file descriptor limits to handle lots of connections.

Cheers,
Daniel

Hi,

I resend this mail because of the initial destination address was not correct.

The topic was a logging problem :

With the upgrade of my SIP Router proxies to RHEL 7  (and Kamailio 5.0.7) , we encounter problems where the logs are blocked to be written in the syslog.

This problem is similar as the one reported in this article : [SR-Users] Kamailio logs in RHEL 7 environment.

The resolution was to increase some journald/rsyslog settings (RateLimitBurst=1000000 / $imjournalRatelimitInterval 1 $imjournalRatelimitBurst 500000).
 
But it is somehow a workaround. 
 
I’m looking to know if it should be possible for kamailio to write directly the logs to the syslog only.
 
Thanks in advance to those can help me.
 

Regards

Patrick Ginhoux
