Win32_PerfFormattedData_Tcpip_NBTConnection class
The Win32_PerfFormattedData_Tcpip_NBTConnection formatted data class provides pre-calculated data from performance counters that monitor the rates at which bytes are sent and received over the NetBIOS over TCP/IP (NBT) connection between the local computer and a remote computer. The connection is identified by the name of the remote computer.
This class is shown as the NBT Connection object in System Monitor. It derives its raw data from the corresponding raw class Win32_PerfRawData_Tcpip_NBTConnection. The original data source is the Tcpip 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 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_PerfFormattedData_Tcpip_NBTConnection class has these properties.
BytesReceivedPerSec
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_BULK_COUNT") , Counter ("BytesReceivedPersec") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Rate at which bytes are received by the local computer over an NBT connection to some remote computer. All the bytes received by the local computer over the particular NBT connection are counted.
For more information about using uint64 values in scripts, see Scripting in WMI.
BytesSentPerSec
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_BULK_COUNT") , Counter ("BytesSentPersec") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Rate at which bytes are sent by the local computer over an NBT connection to some remote computer. All the bytes sent by the local computer over the particular NBT connection are counted.
For more information about using uint64 values in scripts, see Scripting in WMI.
BytesTotalPerSec
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_BULK_COUNT") , Counter ("BytesTotalPersec") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Rate at which bytes are sent or received by the local computer over an NBT connection to some remote computer. All the bytes sent or received by the local computer over the particular NBT connection are counted.

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
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.
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.
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.
