title: Capture my Go application logs into fluentd
body: <p>Currently I have a go web application containing over 50 .go files. Each file writes logs on STDOUT for now. 
  I want to use fluentd to capture these logs and then send them to elasticsearch/kibana.</p>
  
  <p>I search on internet for solution to this. There is one package <a href="https://github.com/fluent/fluent-logger-golang" rel="nofollow">https://github.com/fluent/fluent-logger-golang</a> . 
   To use this I would need to change my whole logging related code in each go file. 
  And there would be many data structures that I would need to Post to fluentd.
  Shortly speaking I dont want to use this approach.</p>
  
  <p>Please let me know if there are any other ways to do this.</p>
  
  <p>Thank you</p>
