Alert: Disk Space full
I have a 500GB drive, and would like to be alerted when it's 85% full.  I tried setting up a WMI monitor using the LogicalDisk \ % Free Space but no matter what range of values I specify, it marks it down when it currently the drive is sitting at 73% free disk space. Are these range of values percentages? 

  • That WMI value is showing % free space so you'd want to set:
    low value 15 (% free space left on the drive)
    high value 100 (% free space left on the drive)
    Edit: if the returned value is out of this range (15-100) then the monitor would be labeled down.
