Win32_PerfRawData_Spooler_PrintQueue - WMI sample in Perl

The foundations for Manageability in Windows 7/2008/Vista/XP/2000 and Millennium Edition/'98 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.


Win32_PerfRawData_Spooler_PrintQueue

Description

The Win32_PerfRawData_Spooler_PrintQueue raw data performance counter class represents raw data performance statistics about a Print Queue. This class is shown as the Print Queue object in Sysmon. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the Spooler performance library. The corresponding formatted data class is Win32_PerfFormattedData_Spooler_PrintQueue. This class was added for Windows 2000.
