title: Make logstash add different inputs to different indices
body: <p>I have setup logstash to use an embedded elastisearch.<br>
  I can log events.<br>
  My logstash conf looks thus:<br>
  <a href="https://gist.github.com/khebbie/42d72d212cf3727a03a0" rel="noreferrer">https://gist.github.com/khebbie/42d72d212cf3727a03a0</a>  </p>
  
  <p>Now I would like to add another udp input and have that input be indexed in another index.</p>
  
  <p>Is that somehow possible?
  I would do it to make reporting easier, so I could have system log events in one index, and business log events in another index.</p>
