<HTML><BODY><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></BODY></HTML>
