How to debug TIME_WAIT in logstash-forwarder

Howdy peeps :-) I know is a long time since my last post here and that the site looks more like deserted island but I want to assure you dear reader that I’m not dead just yet just that I’m covered with work :-P .

So for the past 2 hours I was bashing my head on pretty much everything which came in front of me because of logstash-forwarder and a TIME_WAIT issue. It looks like there is no way to have some kind of logging enabled on the logstash-forwarder (or at least I wasn’t able to find any way of doing it) so I tried pretty much every possible way of debugging why my logstash server is not getting any logs and why I see crap loads of TIME_WAIT.

After my Googling skills failed it finally hit me “Why not just start the client manually and for sure I’ll be able to see any kind of errors it occurs?” . So here it goes what you need to do to debug the logstash-forwarder please be aware that the paths for you might be different :

$ /opt/logstash-forwarder/bin/logstash-forwarder.sh  -config /etc/logstash-forwarder

and that’s pretty much it. If you curious my issue was caused by a rogue SSL certificate!

BTW..this was supposed to be a short rant so I don’t forget the “solution” for the next time :-)
