` codec => rubydebug` will only print on screen.

If you want it to store in files, you will have to use file plugin

```auto
output {
 file {
   path => /tmp/my_output_text_file
   codec => rubydebug { metadata => true }
 }
}

```

Assuming you have a valid input and filter config part, your output should look something like this: output { stdout { codec =\> rubydebug } } The above example will give you a ruby debug output on your console. If you would rather write it to file you can do it like this: output { file { path =\> /tmp/my\_output\_text\_file codec =\> rubydebug } }
