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

It is included in Fluentd's core.

Sample output:

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.

  • Non-Buffered

  • Synchronous
