<p>Hello,<br>
<br>
I have a strange situation by using xlog module. I don't know
for what reason I'm not receiving all logs generated by
kamailio.<br>
<br>
This is the configuration which I'm using in kamailio.cfg:<br>
<br>
</p>
<p>log_facility=LOG_LOCAL0<br>
log_name="kamailio"<br>
log_prefix="{$rm ($mt) | Seq=$cs | Source IP=$si ($proto) | Call
ID=$ci} "</p>
<p># ----- xlog -----<br>
modparam("xlog", "buf_size", 8192)<br>
modparam("xlog", "long_format", 0)<br>
modparam("xlog", "force_color", 1)<br>
modparam("xlog", "log_colors", "L_ERR=cr;L_WARN=px,L_INFO=px")<br>
<br>
This is rsyslog configuration file:<br>
local0.* /var/log/kamailio/kamailio.log<br>
<br>
Kamailio is running under kamailio user, permission for the log
file are as shown below:<br>
-rwxrwxr-x 1 kamailio kamailio 252885132 Dec 2 14:51
/var/log/kamailio/kamailio.log<br>
<br>
In request_route block this is the first line:<br>
<br>
xlog("L_INFO","[START ROUTING]-(Source IP=$si:$sp/Destination
IP=$Ri:$Rp)\n");<br>
<br>
The problem is that not every request is logged in the log-file.
For example, some "INVITES" requests I can find in the log file,
but some of them - I cannot, even that in sngrep I see the
request and the call is successfully processed by kamailio.
Also, for some requests i can see only partial data, not full
call-flow as it supposed to be (for ex. i see only BYE requests,
or ACK response instead of full call flow). <br>
<br>
Does someone have the same issue? If you don't - how are you
dealing with kamailio log files? I'm thinking to send them to
the central ELK stack, but if I have such problems by saving
them locally - I don't see any reason to send them elsewhere.<br>
I may think that the problem could be in rsyslog itself, but how
can I troubleshoot that?<br>
<br>
The traffic on the server is not very high - 30-50 concurrent
calls. As a storage i'm using an SSD disk and xfs filesystem.
Load on the disk - according to iostat/iotop - is minimum. <br>
<br>
OS: CentOS Linux 7 (Core), Kamailio: 5.2.0 (x86_64/linux) 535e13<br>
Thank You.</p>
