Our Control Panel API DiskQuotaGetUsageTotal function always returns 0 MB despite having consumed a large portion of our disk space. When viewing the Usage Chart, the following numbers are displayed: Used Disk Space: 2394 MB Free Disk Space: 606 MB Total Disk Space Purchased: 3000 MB But when viewing the Usage by User, the following numbers are displayed: [siteuser] 0 MB Anonymous ASPNet User: 0 MB ftp: 0 MB I suspect the issue is related to Windows 2012 - IIS 8.0 and the quota numbers provided above. Is there a way (or other interface primitive) to obtain the 2394MB number above via the Control Panel API? I would like to use the data to help avoid an 'out of disk space' situation.
