Hi  
Testing a new 7.5.0 setup. Brand new. Logstash doc says test it with

> logstash -e 'input { stdin { } } output { stdout {} }'

and then enter "hello world" after logstash says "pipeline is started" and I should see a line

> 2013-11-21T01:22:14.405+0000 0.0.0.0 hello world

But I see a json formatted output in the terminal. Is this the supposed the result instead? Everything is fresh install on the system.

> {  
> "@version" =\> "1",  
> "message" =\> "Hello World",  
> "host" =\> "testnode1",  
> "@timestamp" =\> 2019-12-02T20:37:08.373Z  
> }

Thanks  
W

Yes, the default codec used by a stdout output is now rubydebug. In the past that was not true, it was (I think) "plain" which would give the message format you quote.

Right. Got the point.  
part of the testing is using output  
`stdout { codec => rubydebug }`
