Hello guys.
I using an gelf udp input global through 1 nginx load balancer on 2 graylog nodes.
But 2 our graylog nodes dont get the same throughput traffic in.
Here is my capture: http://prntscr.com/fbwu00
Thanks

And this is my nginx conf:
upstream abc {
server : max_fails=3 fail_timeout=30s;
server : max_fails=3 fail_timeout=30s;
}
server {
listen *** udp;
proxy_pass abc;
}

you should check your nginx.conf and log file. Maybe you want to change the balancing method from the default round-robin to hash $remote_addr;

Please look in this nginx blog post to get an idea how to improve your configuration with health checks.
