title: Logstash sincedb file not being created
body: <p>This is my logstash config file:</p>
  
  <pre><code>input {
      file {
          type =&gt; "SystemError"
          path =&gt; "/path/to/file/systemerr/**/*"
          start_position =&gt; "beginning"
          sincedb_path =&gt; "/data/sincedb"
  
          codec =&gt; multiline {
              pattern =&gt; "^\s"
              what =&gt; "previous"
          }      
      }
  }
  </code></pre>
  
  <p>I have even tried not entering sincedb_path at all and using default path</p>
  
  <pre><code>input {
      file {
          type =&gt; "SystemError"
          path =&gt; "/path/to/file/systemerr/**/*"
          start_position =&gt; "beginning"
  
          codec =&gt; multiline {
              pattern =&gt; "^\s"
              what =&gt; "previous"
          }      
      }
  }
  </code></pre>
  
  <p>But even that is not working. My user has rights to the folder that the sincedb file should be written into. I also tried as root user. But nothing is working.</p>
  
  <p>Please help.</p>
