hi there!

My necessity is to see the streaming logs in kibana.  
So, I use tcp input plugin in logstash confg.  
It works properly almost 1 year.

But the problem is that I stream several apps logs to logstash now.  
If I want to change some grok patterns, I have to `stop logstash` service, `edit the config` and `restart logstash` service.  
Then related applications and logstash connections are lost.  
In this situation, I have to do manually re-connect between apps and logstash service.

Is there anyway to `re-connect automatically`  
OR how to update logstash config without `logstash service stops / restarts`?

Plz advise to me.  
Thank you very much!
