Other Disk Types

Mount points or mounted volumes are disks that have been mounted into a folder instead of being assigned a drive letter. This is common where you may have more drives than letters of the alphabet.

NSClient++ 0.4.2.x versions onwards support mounted disks. They will be checked by default or you can target them specifically:

NSClient++ 0.4.2.x
Command:
check_nrpe -H win2008r2-01 -c CheckDriveSize -a ShowAll MaxWarn=5G MaxCrit=10G Drive='C:\Mounted Disks\A Mounted Disk'

Output:

Known Issues

Performance data string returns a percentage data source AND a unit data source. It has been observed that in NSClient++ 0.3.9 that:

  • The unit data source returns incorrect warning and critical values. Example:
    • It SHOULD be:
      • 'C:'=11.51G;50;40;0;59
    • But it returns:
      • 'C:'=11.51GB;2;1;0;59.9
  • The unit data source, when in a warning or critical state returns the warning or critical value in a different unit to what was used in the MinWarn and MinCrit values. Examples:
    • It SHOULD be:
      • 'C:'=11.51G;50;40;0;59
    • But it returns:
      • 'C:'=12361519104B;2147483648;0;0;64317550592
