title: How to troubleshoot Kibana Time-Outs
body: <p>I have been experiencing an issue where occasionally my Kibana stops working stating a time-out trying to connect to elasticsearch as the cause. (I have marvel installed. Something like: "plugin:elasticsearch Request Timeout"</p>
  
  <p>Usually these go away by the next day, and occasionally I have been able to re-gain access to my data by increasing the timeout on kibana. However I can't figure out how to troubleshoot this issue. I suspect it may be that ES is storing some extremely large individual documents but I cannot find them, there's just too many logs to dig through by hand.</p>
  
  <p>My elasticsearch cluster is perfectly healthy (green on health check), even when kibana cannot access it.</p>
  
  <p>Where can I possibly start to try and troubleshoot why we are getting timeouts here? when I expand the timeout window, kibana comes back, and everything works FINE.</p>
  
  <p>Any tips on where to start searching would be enormously appreciated!!</p>
