Hello,

I have a performance question.  
Suppose we have three elasticsearch nodes. The number of logstash is X 😉  
Is it possible to configure the cluster in such a way that traffic from these logstash is distributed evenly? Will connecting all nodes under one domain provide such a thing? Or is it in the configuration on the logstash side?

THX  
Maciej

See the doc for the logstash elasticsearch output plugin. If you give a list of hosts, it load balances across them.
