Hello folks,

I want to get the whole event to a shell script, I am trying to use exec output plugin.

Please note, I don't have "message" variable.  
This is the output in JSON.

> `{"taskid":"vMUKrDoBSX-12349","@version":"1","txn"..}`

Here is my output filter I want to use,

> output {  
> exec {  
> command =\> "myscript.sh ${???}"  
> codec =\> "json\_lines"  
> }  
> }

My question is what should I pass in ??? , since I don't have a message. I want to pass the root of event.
