OID_NDK_STATISTICS
As a query, NDIS and overlying drivers or user-mode applications use the OID_NDK_STATISTICS OID to get the NDK statistics of a miniport adapter.
NDIS 6.30 and later miniport drivers that provide NDK services must support this OID. Otherwise, this OID is optional.
Note NDIS supports this OID with the direct OID request interface. For more information about the direct OID request interface, see NDIS 6.1 Direct OID Request Interface.
Remarks
NDIS issues this OID with the InformationBuffer member of the NDIS_OID_REQUEST structure pointing to an NDIS_NDK_STATISTICS_INFO structure.
The NDK-capable miniport driver must provide the CounterSet member, which is a NDIS_NDK_PERFORMANCE_COUNTERS structure.
The counters are published to tools such as perfmon (see the NetworkDirect Activity performance counter) and made available programmatically with the Performance Data Helper (PDH) and Performance Library (PERFLIB) programming interfaces. For more information about these interfaces, see Performance Counters.
These counters are also available by calling the Get-NetAdapterStatistics PowerShell cmdlet with the RdmaStatistics attribute. For more information about the RdmaStatistics attribute, see MSFT_NetAdapterStatisticsSettingData.
