I am running filebeat on a k8s cluster, and I see this a lot in the index:

      {
    "_index": "filebeat-6.8.0-2019.06.10",
    "_type": "doc",
    "_id": "Hgh5QWsBDoVggnwmKIVx",
    "_score": 1,
    "_source": {
      "@version": "1",
      "tags": [
        "beats_input_raw_event"
      ],
      "@timestamp": "2019-06-10T12:59:46.250Z"
    }

I'm not sure where or how this document is created? Can someone shed some light on this please?

I've tried stopping my application from creating log statements, but this message is till generated.
