Hi Christian,

glad you found something that works for you.  
To tie into your earlier question about doing it with winlogbeat processors thats also possible.

```
processors:
  - drop_fields:
      fields: ["host.name"]
  - copy_fields:
      fields:
        - from: host.hostname
          to: host.name

```

You will have to drop the field first because the copy\_fields function cant write into already existing fields.
