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 ?

[Badger]

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 on that.
