Win32_PerfRawData_PerfDisk_LogicalDisk perl sample code

The foundations for Manageability in Windows is Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself. The Win32_PerfRawData_PerfDisk_LogicalDisk WMI class can be used in ActiveXperts Network Monitor to monitor your servers.
