Win32_CDROMDrive 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_CDROMDrive WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

The Win32_CDROMDrive WMI class represents a CD-ROM drive on a Windows computer system. Note that the name of the drive does not correspond to the logical drive letter assigned to device.
