Hi,

We are currently using the following plugin https://github.com/hotschedules/fluent-plugin-gelf-hs to send logs to Graylog running on EC2.

It seems that fluentd does not support load balancing on the output plugin,

one event:

22:40:12.903520 IP 10.8.93.225.43538 > 100.64.101.161.12201: Flags [P.], seq 1721408233:1721408763, ack 1171098839, win 229, options [nop,nop,TS val 4243364194 ecr 112669536], length 530

an other event:

22:40:12.903528 IP 10.8.93.225.43538 > 100.64.101.161.12201: Flags [P.], seq 0:530, ack 1, win 229, options [nop,nop,TS val 4243364194 ecr 112669536], length 530

So a single TCP connection is being used on the output,

Is there a way to disable that behaviour as the NLB that would sit in front of the Graylog ingress would not load balance the connections to the different instances,
