stdout

The filter_stdout filter plugin prints events to the standard output (or logs if launched as a daemon). This filter plugin is useful for debugging purposes.

It is included in the Fluentd's core.

Example Configurations

<filter pattern>
@type stdout
</filter>

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.
