  ===== fields_under_root
  
  If set to true, the custom <<configuration-fields>> are stored as top level into the output
  document instead of being grouped under a `fields` sub-dictionary. In case of conflicts with
  the fields names added by Filebeat, the custom fields overwrite the existing fields.
  
  ===== ignore_older
  
  If set, ignores the files which were modified more then the defined timespan in the past
  Time strings like 2h (2 hours), 5m (5 minutes) can be used. Default is set to 10m.
  
  ===== scan_frequency
  
  Scan frequency specifies how often the prospector checks for new files in the
  paths that are specified for harvesting. For example, if you specify a glob like
  `/var/log/*`, the directory is scanned for files using the frequency specified by
  scan_frequency. If you specify 0s, the directory is scanned as frequently as
  possible. We recommend that you do not specify 0. The default setting is 10s.
  
  ===== document_type
  
  Defines the event its type value to be used for published lines read by
  harvesters. The document_type will be used by Elasticsearch output as document
  type. Default value is `log`.
  
  
  ===== harvester_buffer_size
  
  Defines the buffer size every harvester uses when fetching the file. By default is 16384.
  
  
  ===== tail_files
