Simple Notification to client of file size on server

[desperadoh]

Hi,

I want to be notified when/if a certain file on my server exceeds a specific size - or even better once a day be notified the actual size of this file.
What is the simplest way to set up such a notification system, without installing too much/too many services (SNMP etc).
A simpel message from server to one client/workstation would do.

Thanks in advance
