title: Understanding the logstash retry policy
body: <p>I have kibana and  elasticsearch instance running on a machine. Logstash and filebeat are running on other machine. </p>
  
  <p>The flow is working perfectly fine. I have one doubt and i need to understand that. I made elasticsearch go down and made logstash to pump some logs to elasticearch. Since elasticsearch is down, i am hoping data will be lost. But when i brought up the elasticsearch service, Kibana was able to show the logs which was sent when elasticsearch was down.</p>
  
  <p>When i googled online, i got to know that logstash retries to connect in elasticsearch is down.</p>
  
  <p>May i please know how to set this parameter</p>
