The file input will add a [path] field to events that contains the filename. You can reference that in the elasticsearch output using

```
document_id => "%{[path]}"
```

Is the %{[path]} gives the full path or just the file name ?

The full path. If you just want the filename part then you can extract it by copying path to another field and using [mutate+gsub](https://discuss.elastic.co/t/one-or-more-inputs-to-one-or-more-outputs/171906/6) on that.
