Win32_PerfRawData_PerfProc_ThreadDetails_Costly - 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_PerfRawData_PerfProc_ThreadDetails_Costly WMI class can be used in ActiveXperts Network Monitor to monitor your servers.



The Win32_PerfRawData_PerfProc_ThreadDetails_Costly raw data performance counter class represents raw data counters that measure aspects of thread behavior that are difficult or time-consuming to collect. These counters are distinguished from those in the Thread object by their high overhead. The suffix "Costly" indicates that obtaining data from the counters contained in this class uses system or network resources heavily and can affect performance. This class is not shown in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the PerfProc performance library. The corresponding formatted data class is Win32_PerfFormattedData_PerfProc_ThreadDetails_Costly. This class was added for Windows 2000.
