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._______________________________________________
