Disk Space Check

The Disk Space Check fails when the available free space on the specified disk drops below the defined Bytes, MBytes, Gbytes or Percent threshold figure.

Disk Space Check configuration examples:

  • Threshold: less than 25%. Disk Space Check fails when free space remaining falls below 25%
  • Threshold: less than 5 GB. Disk Space Check fails when free space remaining is less than 5 GB.

Monitoring Templates

As the hard drive capacities may vary from machine to machine, we would suggest entering a specific threshold value rather than a percentage when adding a Disk Space Check to a Monitoring Template. For example you may wish to be alerted when the drive space falls below 10% on a 10 GByte drive but less concerned if it was 10% of a 1 TByte drive, but in general you would wish to know when the free space falls below 700 MBytes on any size drive.

Access Denied

An access denied message may be returned where the account the Agent service is running under does not have sufficient permissions to query the selected drive and to resolve this either change the Agent service account or change the permissions of the account the Agent service runs under to allow access to the drive.

Local Disks

Please be aware that only those logical drives identified by the computer as Local (DriveType 3) or Compact Disc (DriveType 5) are selectable in this Check. This Check does not support any other drive types included Network (DriveType 4) or Removable (DriveType 2).

The connected drives and their Windows assigned DriveType may be viewed on the device using Powershell:

  1. Log on to the target device
  2. Open the Run dialog (Windows button +R)
  3. Type: powershell then OK
  4. Type Get-WmiObject Win32_LogicalDisk
  5. Hit enter on your keyboard
  6. For each drive the DeviceID, DriveType along with additional information is returned
