relabel

The relabel output plugin re-labels events.

Example Configuration

out_relabel is included in Fluentd's core. No additional installation process is required.

<match pattern>
  @type relabel
  @label @foo
</match>

<label @foo>
  <match patter>
    ...
  </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.

Parameters

type (required)

The value must be relabel.

label

The label.

log_level option

The log_level option allows the user to set different levels of logging for each plugin. The supported log levels are: fatal, error, warn, info, debug, and trace.
