Examples
The following C# sample displays summary information. The referenced utilities can be found in Common utilities for the virtualization samples (V2).
Important
To function correctly, the following code must be run on the virtual machine host server, and must be run with Administrator privileges.
public class GetSummaryInformationClassV2

public static void GetSummaryInformation(string[] vmNames)
{
ManagementScope scope = new ManagementScope(@"root\virtualization\v2", null);

ManagementBaseObject inParams = virtualSystemService.GetMethodParameters("GetSummaryInformation");
ManagementObject[] virtualSystemSettings = new ManagementObject[vmNames.Length];
for (int i = 0; i < vmNames.Length; i++)
{
virtualSystemSettings[i] = GetVirtualSystemSetting(vmNames[i], scope);
}
UInt32[] requestedInformation = new UInt32[4];
requestedInformation[0] = 1; // ElementName
requestedInformation[2] = 103; // MemoryUsage
requestedInformation[3] = 112; // MemoryAvailable
inParams["SettingData"] = virtualSystemSettings;
inParams["RequestedInformation"] = requestedInformation;
ManagementBaseObject outParams = virtualSystemService.InvokeMethod("GetSummaryInformation", inParams, null);
if ((UInt32)outParams["ReturnValue"] == ReturnCode.Completed)
{
Console.WriteLine("Summary information was retrieved successfully.");
ManagementBaseObject[] summaryInformationArray =
(ManagementBaseObject[])outParams["SummaryInformation"];
foreach (ManagementBaseObject summaryInformation in summaryInformationArray)
{
Console.WriteLine("\nVirtual System Summary Information:");
if ((null == summaryInformation["Name"]) ||
(summaryInformation["Name"].ToString().Length == 0))
{
Console.WriteLine("\tThe VM or snapshot could not be found.");
}
else
{
Console.WriteLine("\tName: {0}", summaryInformation["Name"].ToString());

}
}
}
}
}
else
{
Console.WriteLine("Failed to retrieve virtual system summary information");
}
inParams.Dispose();
outParams.Dispose();
virtualSystemService.Dispose();
}
