Greetings, I don't know this is the right place to ask about this question but I will give it a shot. We are running a syslog-ng server and we want to use Kibana as a visualization tool. I got stuck in at this point when configuring conf.d file. source s_tcp { tcp(ip("0.0.0.0") port("514")); udp(ip("0.0.0.0") port("514")); }; destination d_el { elasticsearch2( client-mode("http") index("syslog-ng") type("test") cluster-url(http://10.1.3.222:9200) ); #file("/var/log/networks/$HOST/$YEAR/$MONTH/$HOST-$YEAR-$MONTH-$DAY.log"); }; log { source(s_tcp); destination(d_el); flags(flow-control); }; If I start syslog-ng daemon, I got the below error.
