The relabel output plugin re-labels events.

It is included in Fluentd's core.

Example Configuration

<match pattern>
  @type relabel
  @label @foo
</match>
​
<label @foo>
  <match pattern>
  # ...
  </match>
</label>

The above example puts a label @foo to matched events, and the label directive can take care of these events.

FYI: All of input and output plugins also have @label parameter provided by Fluentd core. The relabel plugin is a plugin which actually does nothing, but supports only @label parameter.
