stdout

A simple output which prints to the STDOUT of the shell running Logstash. This output can be quite convenient when debugging plugin configurations, by allowing instant access to the event data after it has passed through the inputs and filters.

For example, the following output configuration, in conjunction with the Logstash -e command-line flag, will allow you to see the results of your event pipeline for quick iteration.

    output {
      stdout {}
    }

Useful codecs include:

rubydebug: outputs event data using the ruby "awesome_print" library

    output {
      stdout { codec => rubydebug }
    }

json: outputs event data in structured JSON format

    output {
      stdout { codec => json }
    }

stdout {
}
