  == Configuration Options
  
  The configuration file of Filebeat uses http://yaml.org/[YAML] as any other Beat.
  To start with the configuration it is best to have a look at the default configuration. It is described in detail
  what each configuration option is for and how it can be used. Remove the items that are not needed for your setup.
  
  The _etc/filebeat.yml_ consists of the following sections:
  
  * {libbeat}/configuration.html#configuration-shipper[Shipper]
  * {libbeat}/configuration.html#configuration-output[Output]

  ===== encoding
  
  The file encoding to use for reading files that contain international characters.
  See the encoding names http://www.w3.org/TR/encoding/[recommended by the W3C for use in HTML5].
  
  Here are some sample encodings from W3C recommendation:
  
      * plain, latin1, utf-8, utf-16be-bom, utf-16be, utf-16le, big5, gb18030, gbk, hz-gb-2312,
      * euc-kr, euc-jp, iso-2022-jp, shift-jis, and so on
  
  The `plain` encoding is special, because it does not validate or transform any input.
