Monitor file size on a Samba drive (Linux)

Good morning all.
I need to check a filesize on a remote samba drive. I understand the smb plugins, however, I need to monitor file sizes within a dir rather than just a diskspace %.
I have looked at the check_filesize.pl plugin but obviously a username and pass is needed to monitor a remote file on a samba server.

Does anyone know if a plugin to do this exists?

Cheers :wink:
