title: How to get Stdout from a service into logstash
body: <p>I understand that a similar question was asked here:
  <a href="https://stackoverflow.com/questions/29479311/how-can-i-configure-logtash-to-use-stdout-as-input">How can I configure logtash to use &quot;stdout&quot; as input?</a>, but I wanted to generalize the question a little.</p>
  
  <p>What I have currently configured is the basic ELK stack(elasticSearch, logstash, kibana) on a Linux VM and I want to feed a bit of standard output into logstash in order to remove log files from the file system, thus not consuming disk space.</p>
  
  <p>So for example, how would I take the std-out from say, Kibana, and feed that directly into Logstash?</p>
  
  <p>Any pointers in the right direction would be appreciated.</p>
