stdout

The stdout output plugin prints events to stdout (or logs if launched with daemon mode). This output plugin is useful for debugging purposes.

Example Configuration

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

<match pattern>
@type stdout
</match>

Please see the Config File article for the basic structure and syntax of the configuration file.

A sample output is as follows:

2017-11-28 11:43:13.814351757 +0900 tag: {"field1":"value1","field2":"value2"}

where the first part shows the output time, the second part shows the tag, and the third part shows the record.
