I Setup ELk : LS Forwarder -\> RabbitMQ -\> Logstash Proccessor -\> ES  
ES ver 2.1.1; Rabbit 3.6.1; LS newest.  
I have 2 LS-Forwarder (8Core, 8GB RAM), 2Rabbitmq (cluster HA - 8Core, 8GB RAM), 2 LS-Processer (8Core, 8GB RAM) and 3 ES (16Core -16GB RAM).

I check log in LS-Processer and got :

```
