Win32_OperatingSystem 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_OperatingSystem WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

The Win32_OperatingSystem WMI class represents an operating system installed on a Win32 computer system. Any operating system that can be installed on a Win32 system is a descendent (or member) of this class. If the computer has multiple operating systems installed, this class returns only an instance for the currently active operating system.

Sample Code

use Win32::OLE('in');

use constant wbemFlagReturnImmediately => 0x10;
use constant wbemFlagForwardOnly => 0x20;
