Gateway timer script that runs at a set rate(1s or 5s) to check the number of files in the folder or get total size of all items in the folder. Once its above a limit, send out a warning email, or set a memory tag to `1` and have an alarm defined on that tag. The folder will need to be accessible from the gateway device, as perspective does not have access to the local client's filesystem.
