title: Graylog2 sidecar collector logs not showing up on the dashboard
body: <p>Installed the sidecar collector and configured it with the filebeat backend. It's running successfully. Made an output and attached some inputs to it with general log files. No logs showing up on the dashboard yet. Here's my debug output, which gives me nothing useful:</p>
  
  <pre><code>sudo service collector-sidecar stop
  graylog-collector-sidecar -c /etc/graylog/collector-sidecar/collector_sidecar.yml
  INFO[0000] Using collector-id: xxx
  INFO[0000] Fetching configurations tagged by: [syslog linux] 
  INFO[0000] Starting collector supervisor                
  INFO[0000] [filebeat] Starting                          
  INFO[0010] [filebeat] Configuration change detected, rewriting configuration file. 
  INFO[0010] [filebeat] Stopping                          
  INFO[0014] [filebeat] Starting                          
  </code></pre>
  
  <p>Should I also make a <code>system -&gt; input</code>? How can I debug the fact that logs are not showing up? What am I missing here?</p>
