<div dir="ltr"><div dir="ltr"><div>Hi,</div><div><br></div><div>After repeating the test without TLS between syslog-agent & syslog-relay, with 2229 messages logged with a 20 msgs/sec logging ratio, in debug mode and with two tcpdumps running, these are the conclussions:</div><div></div><div><br></div><div>- Syslog-agent sends every single message (checked with tcpdump file and syslog-agent log file)<br></div><div>- Syslog-relay returns ACK for every single message, but sometimes the package contains more than one message (checked with tcpdump file)<br></div><div>- Checking the syslog-relay log after killing & starting the docker container, I found the trace 'Reliable disk-buffer state loaded; filename='/syslog-ng-00000.<wbr>rqf', queue_length='99', size='173844' and the queued messages (from msg 236 to msg 334 are processed). The next message processed is the nº 440. and it comes from the active network destination again.</div><div>- Once all logs have been processed, in elasticsearch (syslog-relay destination) I can find messages from 1 to 334, and messages from 440 to 2229.<br></div><div><br></div><div>How is it possible that syslog-relay returns ACK for messages 335 to 439 to syslog-agent, but they are not in the queue, nor in the .rqf file? Where did these messages go? I know they are sent before starting to fill syslog-agent disk-buffer file (checked with rqf file from syslog-agent when I kill the syslog-relay container). It seems that there's some kind of race condition that makes those messages are not processed/queued while syslog-relay is being killed.<br></div><div><br></div><div>Mi procedure consists of:</div><div><br></div><div>. Start tcpdump on both syslog-agent & syslog-relay hosts<br></div><div>- Start logger process</div><div>- Once logs are being inserted in elasticsearch, I kill the syslog-relay docker container, wait about 10 seconds, and run a new container (using a mapped volume where .rqf file and .persist file are)</div><div>- Once logs are being inserted in elasticsearch again, I stop the logger process.</div><div>- I wait until no log is left to be processed</div><div><br></div><div>Would you test anything else? I'm running out of ideas.</div><div><br></div><div>PD: Same test with logger process writing 5 msgs/sec ratio produces from 0 to 5 lost messages.<br></div><div><br></div><div>Regards.<br></div><div><br></div><div><br></div><div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">2018-09-14 14:05 GMT+02:00 Jose Angel Santiago <span dir="ltr"><<a href="mailto:jasantiago@stratio.com" target="_blank">jasantiago@stratio.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr"><div>Hi,</div><div><br></div><div>I've got more accurate information about where are my lost messages.</div><div><br></div><div>Now I'm using disk-buffer in syslog-agent and syslog-relay, and I've checked that lost messages are the ones sent by the syslog-agent when the syslog-relay docker container is being killed.
