Win32-PerfRawData-PerfNet-ServerWorkQueues - WMI Perl sample

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

Win32-PerfRawData-PerfNet-ServerWorkQueues

Description

The Win32_PerfFormattedData_PerfNet_ServerWorkQueues "cooked" data performance counter class represents calculated counters that monitor the length of the queues and objects in the queues. This class is shown as the Server Work Queues object in System Monitor. The WMI source of its data is the high-performance Cooked Counter Provider. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfNet_ServerWorkQueues. The original data source is the PerfNet performance library. This class was added for Windows XP.
