Hi Logstash Team.

I'd like to load data struct as below.  
INPUT:  
{  
"vmdata":{  
"vm1": "UP",  
"vm2": "Down",  
"vm3": "UP"  
.....  
}  
}

OUTPUT:  
event: vm1: "UP"  
event: vm2: "Down"  
....  
event: ...

Anybody can help? very appreciate!

Finally I am able to do it by ruby filter.

```
 ruby{
    init => "require 'json'"
    code => "
      event.get('[data][hostlist]').to_hash.each do |k,v|  
         newevent = event.clone
        newevent.set('vm', k)
        newevent.set('status' , v)
        newevent.remove('vmdata')
        new_event_block.call(newevent)        
      end
    "
   }
```
