Hello,
typically syslog has some rate limiting, and with centos, you get extra
limits with selinux. You have to dive into rsyslog, system config and
selinux.
What you can do is to start with log_stderror=yes (or -E command line
option) and see if it is printing the messages you are looking for to
the terminal. You can eventually direct sderror to a file to be easier
to search/match...
Cheers,
Daniel

Hello,
Actually, async Syslog option was the initial option which I tried -
it wasn't working properly so I changed to a synchronous mode in the
hope that it will work better, but unfortunately it didn't.

Hello,
try with async syslogging option in rsyslog config: add a - in
front of the file name, like:
local0.* -/var/log/kamailio/kamailio.log
See if the results are better.
Cheers,
Daniel

Hello,
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.
This is the configuration which I'm using in kamailio.cfg:
log_facility=LOG_LOCAL0
log_name="kamailio"
log_prefix="{$rm ($mt) | Seq=$cs | Source IP=$si ($proto) | Call
ID=$ci} "
# ----- xlog -----
modparam("xlog", "buf_size", 8192)
modparam("xlog", "long_format", 0)
modparam("xlog", "force_color", 1)
modparam("xlog", "log_colors",
"L_ERR=cr;L_WARN=px,L_INFO=px")
This is rsyslog configuration file:
local0.* /var/log/kamailio/kamailio.log
Kamailio is running under kamailio user, permission for the log
file are as shown below:
-rwxrwxr-x 1 kamailio kamailio 252885132 Dec 2 14:51
/var/log/kamailio/kamailio.log
In request_route block this is the first line:
xlog("L_INFO","[START ROUTING]-(Source IP=$si:$sp/Destination
IP=$Ri:$Rp)\n");
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).
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.
I may think that the problem could be in rsyslog itself, but how
can I troubleshoot that?
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.
OS: CentOS Linux 7 (Core), Kamailio: 5.2.0 (x86_64/linux) 535e13
Thank You.
