Can I set Email Alerts for Low Free Disk Space

I just realized that the Free space on my WD is almost nothing (10MB). I have an email alert setup for Critical and Warnings but I have not been getting any. Should there be an alarm for low disk space?
Also, I do not know the definition of a Critical or Waning alarm. Any help would be appreciated.

I have the WD MyCloud EX series
OS is at : v04.05.00-342
