Win32_PerfFormattedData_PerfProc_Image_Costly class
The Win32_PerfFormattedData_PerfProc_Image_Costly formatted data class provides precalculated data from performance counters that monitor counters that monitor the virtual address usage of images executed by processes on the computer.
This class is shown as the Image object in System Monitor and returns the same data found in System Monitor. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfProc_Image_Costly. The original data source is the PerfProc performance library. Data is dynamically provided for this class from the performance library object by the WmiPerfInst provider.
Windows Server 2003 and Windows XP: WMI data for this class is supplied by the Formatted Performance Data Provider.
The suffix "Costly" indicates that obtaining data from the counters contained in this class uses system or network resources heavily and can affect performance.
The following syntax is simplified from MOF code and shows all inherited properties, including the Frequency and Timestamp properties required for class display in System Monitor. For more information about required property qualifiers, see Property Qualifiers for Performance Counter Classes. For more information about CounterType values, see WMI Performance Counter Types.

- Properties
Properties
The Win32_PerfFormattedData_PerfProc_Image_Costly class has these properties.
Caption
Data type: string
Access type: Read-only
Short textual description for the statistic or metric. This property is inherited from CIM_StatisticalInformation.
Description
Data type: string
Access type: Read-only
Textual description of the statistic or metric. This property is inherited from CIM_StatisticalInformation.
ExecReadOnly
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("ExecReadOnly") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Memory that can be executed as well as read.
For more information about using uint64 values in scripts, see Scripting in WMI.
ExecReadPerWrite
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("ExecReadPerWrite") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Memory that can be executed by programs as well as read and written.
For more information about using uint64 values in scripts, see Scripting in WMI.
Executable
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("Executable") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Memory that can be executed by programs, but cannot be read or written. This type of protection is not supported by all processor types.
For more information about using uint64 values in scripts, see Scripting in WMI.
ExecWriteCopy
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("ExecWriteCopy") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Memory that can be executed by programs as well as read and written. This type of protection is used when memory must be shared between processes. If the sharing processes only read the memory, then they all use the same memory. If a sharing process requests write access, then a copy of this memory is made for that process.
For more information about using uint64 values in scripts, see Scripting in WMI.
Frequency_Object
Data type: uint64
Access type: Read-only
Frequency, in ticks per second, of Timestamp_Object. This property is defined by the provider. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
Frequency_PerfTime
Data type: uint64
Access type: Read-only
Frequency, in ticks per second, of Timestamp_Perftime. A value could be obtained by calling the Windows function QueryPerformanceCounter. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
Frequency_Sys100NS
Data type: uint64
Access type: Read-only
Frequency, in ticks per second, of Timestamp_Sys100NS (10000000). This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
Name
Data type: string
Access type: Read-only
Label by which the statistic or metric is known. When sub-classed, the property can be overridden to be a key property. This property is inherited from CIM_StatisticalInformation.
NoAccess
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("NoAccess") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Protection that prevents a process from writing or reading these pages and generates an access violation if either is attempted.
For more information about using uint64 values in scripts, see Scripting in WMI.
ReadOnly
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("ReadOnly") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Protection that prevents the modification of pages with this protection. Any attempts to write or modify these pages generates an access violation.
For more information about using uint64 values in scripts, see Scripting in WMI.
ReadPerWrite
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("ReadPerWrite") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Protection that allows a process to read, modify, and write to these pages.
For more information about using uint64 values in scripts, see Scripting in WMI.
Timestamp_Object
Data type: uint64
Access type: Read-only
Object-defined timestamp, defined by the provider. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
Timestamp_PerfTime
Data type: uint64
Access type: Read-only
High Performance counter timestamp. A value could be obtained by calling the Windows function QueryPerformanceCounter. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
Timestamp_Sys100NS
Data type: uint64
Access type: Read-only
Timestamp value in 100 nanosecond units. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
WriteCopy
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("WriteCopy") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Protection used when memory is shared for reading but not for writing. When processes are reading this memory, they can share the same memory; however, when a sharing process requests read/write access, a copy of the memory is made for the process that requires read/write access.
For more information about using uint64 values in scripts, see Scripting in WMI.
