make sure that you put stdout { codec =\> rubydebug } in the output section. such as this

```
> output { #The output section tells where the output will go
> elasticsearch{ #Output will be going to elasticsearch  
> hosts => ["elasticsearch:9200"]                           
> index => "finalindex" #name of the index that the output will be stored
> }
> stdout { codec => rubydebug } #Outputs the contents of the message to the command prompt
> }

```

if you still arent getting any output then you likely have an issue with how you are getting your input
