C# 为VM读取RAM和磁盘利用率'；在Hyper-V中使用WMI类

我不熟悉WMI类，我想在C#code中使用WMI类读取Hyper-V上不同虚拟机的CPU、RAM和磁盘利用率

CPU利用率：能够通过使用属性ProcessorLoad和ProcessorLoadHistory获取它

     ManagementBaseObject outParams = virtualSystemService.InvokeMethod("GetSummaryInformation", inParams, null);

     ManagementBaseObject[] summaryInformationArray = (ManagementBaseObject[])outParams["SummaryInformation"];

RAM利用率：无法获取动态和静态分配的当前RAM利用率的准确值。 “Msvm_MemorySettingData”类的VirtualQuantity和Reservation property给出了动态RAM情况下的启动RAM值，以及静态RAM情况下分配的RAM的最小值

硬盘利用率：无法获取每个虚拟机的硬盘利用率

我的代码是：

public static ManagementObject GetTargetComputer(string vmElementName, ManagementScope scope)
    {
        string query = string.Format("select * from Msvm_ComputerSystem Where ElementName = '{0}'", vmElementName);

        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, new ObjectQuery(query));

        ManagementObjectCollection computers = searcher.Get();

        ManagementObject computer = null;

        foreach (ManagementObject instance in computers)
        {
            computer = instance;
            break;
        }
        return computer;
    }

void GetSummaryInformation(ManagementObject virtualSystemSettings, UInt32[] requestedInformation, ManagementObject virtualSystemService)
    {
        ManagementBaseObject inParams = virtualSystemService.GetMethodParameters("GetSummaryInformation");
        string[] settingPaths = new string[1];
        settingPaths[0] = virtualSystemSettings.Path.Path;
        inParams["SettingData"] = settingPaths;
        inParams["RequestedInformation"] = requestedInformation;
        ManagementBaseObject outParams = virtualSystemService.InvokeMethod("GetSummaryInformation", inParams, null);

        UInt32 v = (UInt32)outParams["ReturnValue"];

        if ((UInt32)outParams["ReturnValue"] == 0)
        {
            ManagementBaseObject[] summaryInformationArray = (ManagementBaseObject[])outParams["SummaryInformation"];

            foreach (ManagementBaseObject summaryInformation in summaryInformationArray)
            {

                foreach (UInt32 requested in requestedInformation)
                {
                    string Name = summaryInformation["Name"].ToString();
                    switch (requested)//103, 106, 109, 104, 3, 4, 101, 105
                    {

                        case 103:
                            string MemoryUsage = summaryInformation["MemoryUsage"].ToString();
                            break;
                        case 112:
                            Int32 MemoryAvailable = (Int32)summaryInformation["MemoryAvailable"];
                            break;
                        case 113:
                            Int32 AvailableMemoryBuffer = (Int32)summaryInformation["AvailableMemoryBuffer"];
                            break;
                    }
                }
            }
        }
        else
        {
            Console.WriteLine("Failed to retrieve virtual system summary information");
        }

        inParams.Dispose();
        outParams.Dispose();
    }


ManagementObject virtualSystem = GetTargetComputer(vm["ElementName"].ToString(), Scope);

            ManagementObjectCollection virtualSystemSettings = virtualSystem.GetRelated
           (
               "Msvm_VirtualSystemSettingData",
               "Msvm_SettingsDefineState",
               null,
               null,
               "SettingData",
               "ManagedElement",
               false,
               null
           );
            ManagementObject virtualSystemSetting = null;               
            foreach (ManagementObject instance in virtualSystemSettings)
            {
                virtualSystemSetting = instance;

                foreach (ManagementObject memorySettingData in virtualSystemSetting.GetRelated("Msvm_MemorySettingData"))
                {
                    string HeartBeat = (string)memorySettingData["Heartbeat"];
                    string MemoryUsage = (string)memorySettingData["MemoryUsage"];
                    string VirtualQuantity = (string)memorySettingData["VirtualQuantity"];
                    string Limit = (string)memorySettingData["Limit"];
                }


            }
            UInt32[] requestedInfo = { 103, 112, 113 };
            GetSummaryInformation(virtualSystemSetting, requestedInfo, virtualSystemService);

是否可以使用WMI类获取Hyper-V中每个单独虚拟机的当前RAM利用率和硬盘利用率？

要了解RAM利用率，您可能需要查看以下“Hyper-V动态内存”示例：

它还可以帮助您了解如何获取所需的其他信息。
