Logical Disk Free Space Monitor Type

Microsoft.Windows.Server.10.0.Legacy.LogicalDisk.FreeSpace.Monitortype (UnitMonitorType)

Knowledge Base article:

Summary

This monitor type checks the logical disk free space on Windows Server 2016.

Configuration

Here is the list of overridable parameters:

Interval Seconds: How frequently (in seconds) the value should be sampled. The default value is 3600
Warning MBytes Threshold for System Drive: The default value is 500
Warning % Threshold for System Drives: The default value is 10
Error MBytes Threshold for System Drives: The default value is 300
Error % Threshold for System Drives: The default value is 5
Warning threshold in MBytes for the non system drives: The default value is 2000
Warning % Threshold for Non-System Drives: The default value is 10
Error threshold in MBytes for the non system drives: The default value is 1000
Error % Threshold for Non-System Drives: The default value is 5
Timeout Seconds: Number of seconds that the script is allowed to run before it will be forced to stop. The default value is 360.
Debug Flag: This setting enables the script to log different events at running time. The default value is false.
