MSiSCSI_NICPerformance WMI 類別

MSiSCSI_NICPerformance WMI 類別會公開網路介面卡 (NIC) 埠的效能統計數據。 註冊此類別的迷你埠驅動程序應該為配接器上的每個埠建立類別的一個實例。

啟動器應該針對適配卡上每個乙太網路埠實作一個MSiSCSI_NICPerformance類別的實例，並針對埠註冊特定實體裝置物件名稱的每個實例， (PDO) 。

MSiSCSI_NICPerformance類別定義於 Iscsiprf.mof 中。

class MSiSCSI_NICPerformance : Win32_PerfRawData {
  [key] string  InstanceName;
  boolean  Active;
  [read, WmiDataId(1), PerfDefault, 
    CounterType(PERF_COUNTER_COUNTER),
    //    32bit per sec display
    DefaultScale(0), PerfDetail(100), description("Number of 
    bytes per second transmitted via Ethernet port") : 
    amended] 
    uint32  BytesTransmitted;
  [read, WmiDataId(2), PerfDefault, 
    CounterType(PERF_COUNTER_COUNTER),
    //    32bit per sec display
    DefaultScale(0), PerfDetail(100), description("Number of 
    bytes per second received via Ethernet port") : amended] 
    uint32  BytesReceived;
  [read, WmiDataId(3), PerfDefault, 
    CounterType(PERF_COUNTER_COUNTER),
    //    32bit per sec display
    DefaultScale(0), PerfDetail(100), description("Number of 
    bytes per second transmitted via Ethernet port") :
    amended] 
    uint32  PDUTransmitted;
  [read, WmiDataId(4), PerfDefault, 
    CounterType(PERF_COUNTER_COUNTER),
    //    32bit per sec display
    DefaultScale(0), PerfDetail(100), description("Number of 
    bytes per second received via Ethernet port") : amended]
    uint32  PDUReceived;
};

當 WMI 工具套件編譯上述類別定義時，會產生 MSiSCSI_NICPerformance 數據結構。
