Win32_PerfRawData_NTFSDRV_SMTPNTFSStoreDriver class
The Win32_PerfRawData_NTFSDRV_SMTPNTFSStoreDriver raw performance data class provides raw data from performance counters that monitor the Exchange NTFS Store driver. This class is found only on server operating systems.
This class represents the SMTPNTFSStoreDriver object in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the NTFSDRV performance library. The corresponding formatted data class is Win32_PerfFormattedData_NTFSDRV_SMTPNTFSStoreDriver. 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 Performance Counter Provider.
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
The Win32_PerfRawData_NTFSDRV_SMTPNTFSStoreDriver 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.
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

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 can 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

For more information about using uint64 values in scripts, see Scripting in WMI.
Remarks
All classes derived from Win32_Perf are designed to be used with a refresher object. For more information about how to create and use a refresher object in C++, see Accessing Performance Data in C++. For more information about how to create and use a refresher object using scripts, see Refreshing WMI Data in Scripts.
The performance class and property qualifiers determine how to interpret the class data. For more information, see Class Qualifiers for Performance Counter Classes and Property Qualifiers for Performance Counter Classes.
