Installation

Configuration

This plugin is a parser plugin. After installed, you can use multi_format in <parse> supported plugins. Use multiple <pattern>s to specify multiple parser formats.

<source>
  @type udp
  tag logs.multi

  <parse>
    @type multi_format
    <pattern>
      format apache
    </pattern>
    <pattern>
      format json
      time_key timestamp
    </pattern>
    <pattern>
      format none
    </pattern>
  </parse>
</source>

multi_format tries pattern matching from top to bottom and returns parsed result when matched.

Available format patterns and parameters are depends on Fluentd parsers. See parser plugin document for more details.

For v1.0/v0.14

Put <pattern>s inside <parse>.

<filter app.**>
  @type parser
  key_name message
  <parse>
    @type multi_format
    <pattern>
      format json
    </pattern>
    <pattern>
      format regexp
      expression /...your regexp pattern.../
    </pattern>
    <pattern>
      format none
    </pattern>
  </parse>
</filter>

For v0.12

Use format instead of <parse></parse>.

<filter app.**>
  @type parser
  key_name message

  format multi_format
  <pattern>
    format json
  </pattern>
  <pattern>
    format /...your regexp pattern.../
  </pattern>
  <pattern>
    format none
  </pattern>
</filter>

NOTE

This plugin doesn't work with multiline parsers because parser itself doesn't store previous lines.
