fluent-plugin-reemit

Fluentd plugin to re-emit messages avoiding infinity match loop to achieve branching of data flow.

NOTE: I recommend to use built-in label feature to achieve branching of data flow for Fluentd > v0.12. See below

Fluentd > v0.12 has the label feature. You can achieve branching of data flow without using reemit plugin. I recommend to use the label feature instead of reemit plugin for Fluentd > v0.12.

<source>
  type forward
  @label @raw
</source>

<label @raw>
  <match **>
    type copy
    <store>
      type flowcounter
      count_keys *
      @label @flowcounter
    </store>
    <store>
      type relabel
      @label @normal
    </store>
  </match>
</label>

<label @flowcounter>
  <match **>
    type stdout # results of flowcounter
  </match>
</label>

<label @normal>
  <match **>
    type stdout # normal flow
  </match>
</label>

Use RubyGems:

gem install fluent-plugin-reemit

Example:

This example applies flowcounter plugin for all messages, then re-emit messages. But, the re-emitted messages will skip the identical match directive (the first one) to avoid an infinity loop.

This enables you to achieve branching of data flow without modifing tags of messages and match conditions.

<match flowcount>
  type stdout
</match>

<match **>
  type copy
  <store>
    type flowcounter
    count_keys *
  </store>
  <store>
    type reemit
  </store>
</match>

<match **>
  type stdout
</match>
