Hi everybody,

I have 2 logstash instances in 2 different hosts with the same configurations and a source that sends in tcp.  
It's possible to have a logstash cluster? Or do I have to put a load balancer that send events into the 2 logstash?  
How can a load balancer be done on logstash instances?

Thanks

Daniele

logstash does not have support for clusters that distribute processing of events. A typical load balancer in front of logstash would load balance connections, so if the source only makes one connection it would only send events to one of the two instances.
