Hi

I am using dead letter queue with logstash and i see various empty log files like .log in /var/log/logstash/deadletter folder.  
Why are the log files empty ? Does it mean that events are processed successfully ?  
When are the log files created in deadletter apart from when the logstash is started?  
Please, help me out on this.
