Disk free space monitor reports not received for Server 2012 R2

I have added the disk free condition to performance monitoring in a custom profile. I have tested that this works in Windows 10, however in Server 2012 R2 I only get the other conditions reported and not the low disk threshold notification. Is there a special system requirement for this condition to work or some other reason I would get other notifications but not the disk notification?

This is actually working. Think I my have had issues assigning multiple profiles with similar conditions.

@cmdln ,
