title: There's a way to make Logstash Forwarder send only new logs?
body: <p>I'm using the follow configuration file for my Logstash Forwarder:</p>
  
  <pre><code>{
    "network": {
      "servers": [ "logstash-server:logstash-door" ],
      "ssl ca": "server.crt",
      "timeout": 15
    },
  
    "files": [
      {
        "paths": [ "myLogFile.log" ],
        "fields": { "type": "myLog" }
      }
    ]
  }
  </code></pre>
  
  <p>It works fine. But if the application stops, when i bring it back on it will send the old logs to my logstash-server again. That is a big problem, is there any way to avoid it resending old logs?</p>
