Win32_PageFileSetting - WMI sample in Perl

The foundations for Manageability in Windows 2019/2016/2012/2008 and Windows 10/7/XP are 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.

On this site, you can find many WMI samples.

The Win32_PageFileSetting WMI class can be used in ActiveXperts Network Monitor to monitor your servers.



The Win32_PageFileSetting WMI class represents the settings of a page file. Information contained within objects instantiated from this class specify the page file parameters used when the file is created at system startup. The properties in this class can be modified and deferred until startup. These settings are different from the run-time state of a page file expressed through the associated class Win32_PageFileUsage.
