OK, so a UNIX path contain directory names separated by /. A directory name cannot contain /. So you could either go after the 4th directory name, or the last but one directory name. Either of these should work

```
    grok { match => ["message", "^/[^/]+/[^/]+/[^/]+/(?<dir1>[^/]+)" ] }
    grok { match => ["message", "/(?<dir2>[^/]+)/[^/]+/[^/]+$" ] }
```
