Hello,

I read the documentation about the ruby script and I did not correctly understand the conversion of the ruby script into a file.

If I have a converted ruby script into a file, do I have to rewrite the script into classes?

For example, I wanted to put this ruby script in a file, but it didn't work there at all. When I have this in filter section, it works:

> ```
> ruby {
> code => "
> event.set('[event][duration_seconds]', event.get('[event][duration]').to_f / 1000)
> "} 
> 
> ```

I put it into the file. In the filter was:

> ruby {  
> path =\> "{{logstash.scripts\_path}}/count.rb"  
> }

The content of the file was:

> ```
> event.set('[event][duration_seconds]', event.get('[event][duration]').to_f / 1000)
> 
> ```

Why it didn´t work?

Thank you

Regards,  
Catherine

To convert an inline script to a file you need to define two functions. Try creating a file containing

```auto
def register (params)
end

def filter (event)
    event.set("[event][duration_seconds]", event.get("[event][duration]").to_f / 1000)
    return [event]
end

```

I understand. Thank you so much! 🙂  
Is possible to add also ruby id? I mean: **id =\> "X1\_RUBY"**

ruby {  
**id =\> "X1\_RUBY"**  
code =\> "  
event.set('[event][duration\_seconds]', event.get('[event][duration]').to\_f / 1000)  
"}

Yes, id is a common option that all filters support.
