Win32_PerfRawData_PerfDisk_PhysicalDisk - 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_PerfDisk_PhysicalDisk

Description

The Win32_PerfFormattedData_PerfDisk_LogicalDisk "cooked" data performance counter class represents calculated counters that monitor logical partitions of a hard or fixed disk drive. System Monitor identifies logical disk instances by the drive letter, such as C. This class is shown as the Logical Disk 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_PerfDisk_LogicalDisk. The original data source is the PerfDisk performance library. This class was added for Windows XP.
