Get Foldername from file sent by filebeat

How can i get the folder name of a file sent by filebeat??

i tried this:
> grok {
> path => "/path/to/folder/%{WORD:foldername}/%{GREEDYDATA}"
> }

but it s not working :confused:

That's not what a grok filter looks like. It has the following form:

grok {
  match => {
    "name of field to match against" => "grok expression"

There are concrete examples in the documentation.
