這個WMI類。PacketReceived /秒值非常高

我得到PacketReceived /秒，但它的值高於120000.我認爲它的字節每秒被接收。我還有其他的價值和它的正確

int WMIClass::ExcuteQuery(const char* cstr,LPWSTR atrb) 
{ 
    hres = pSvc->ExecQuery(
    bstr_t("WQL"), 
    bstr_t(cstr), 
    WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
    NULL, 
    &pEnumerator); 

    while (pEnumerator) 
    { 
    hres = pEnumerator->Next(WBEM_INFINITE, 1, 
     &pclsObj, &uReturn); 
    if(0 == uReturn) 
    { 
     break; 
    } 
    VARIANT vtProp; 

    // Get the value of the Name property 
    hres = pclsObj->Get(atrb, 0, &vtProp, 0, 0); 

    intVal=vtProp.uintVal; 
} 
return intVal; 
}

計劃excutes正常和值可以輕鬆地閱讀，但我懷疑這個值。我需要在網絡適配器上每秒接收數據包。任何簡單的解決方案？如果在Qt框架中，將不勝感激。

我看不到'intVal'被初始化的位置，如果它是一個成員變量，你可能正在運行一個前面的值被返回或返回未初始化內存的值。在你的代碼中，你應該處理'Get'操作失敗，無論是來自未知屬性名稱還是其他失敗;如果失敗，你應該返回一個錯誤值或拋出和異常。 – joshperry

確保你正確初始化INTVAL：

int WMIClass::ExcuteQuery(const char* cstr,LPWSTR atrb) { 
    int intVal = 0; 

    hres = pSvc->ExecQuery(
     bstr_t("WQL"), 
     bstr_t(cstr), 
     WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
     NULL, 
     &pEnumerator); 

    while (pEnumerator) { 
     hres = pEnumerator->Next(WBEM_INFINITE, 1, 
      &pclsObj, &uReturn); 

     if(0 == uReturn) 
      break; 

     VARIANT vtProp; 

     // Get the value of the Name property 
     hres = pclsObj->Get(atrb, 0, &vtProp, 0, 0); 

     intVal = vtProp.uintVal; 
    } 

    return intVal; 
}

不過該範圍我得到這些值 PacketReceived /秒= 4453164 PacketReceived /秒= 4453444 PacketReceived /秒= 4453724 PacketReceived /秒= 4454004 PacketReceived /秒= 4453164 PacketReceived /秒= 4453444 PacketReceived /秒= 4453724 PacketReceived/Sec = 4454004 –

我想，它是BytesReceived/Sec的值。 –

Win32_PerfRawData返回原始計數器值所以實際上不是「每秒」。您需要使用Win32_PerfFormattedData值來獲取該值。
