Hello,  
We are trying to forward windows event log shipped with winlogbeat via logstash output syslog. The problem is that we want to forward all fields (ideally key1=value1 key2=value2...) and not just the message field. We can't construct a new field concatenating all the others because we don't know which field will be available depending on the windows event log. Is it possible to use the \_source field like :

> ```
> Output {
> syslog{
> message => "%{_source}"
> }
> }
> 
> ```

because this field is exactly what we want to forward via syslog.  
Thank you for your help !!

Actually you can do exactly that using a ruby filter

```
    ruby {
        init => '@ignore = ["@metadata", "@version"]'
        code => '
            s = ""
            event.to_hash.each { |k, v|
                unless @ignore.include?(k)
                    s = s + "#{k}=#{v},"
                end
                event.set("message", s.chomp(","))
            }
        '
    }

```
