Hello there,

I am trying to get ram, cpu and disk data from windows server 2012 with a sample code like below;

private static void Main(string[] args)
            //can you add try catch to this code
                string vmName = "windows1";  // Replace with your VM name
                ManagementScope scope = new ManagementScope(@"\\.\ROOT\virtualization\v2");

                // Query for the virtual machine
                ObjectQuery query = new ObjectQuery(string.Format("SELECT * FROM Msvm_ComputerSystem WHERE ElementName = '{0}'", vmName));

                // Execute the query
                using ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
                foreach (ManagementObject queryObj in searcher.Get())
                    // Get the memory
                    Console.WriteLine("Memory: {0}", queryObj["TotalMemory"]);

                    // Get the disks
                    using ManagementObjectCollection relatedDisks = queryObj.GetRelated("Msvm_VirtualHardDisk");
                    foreach (ManagementObject disk in relatedDisks)
                        Console.WriteLine("Disk path: {0}", disk["Path"]);
            catch (Exception e)

What I have tried:

But I am getting invalid namespace, how can I fix this?

1 solution

It's telling you the namespace "virtualization\V2" doesn't exist on the machine. You don't have the Hyper-V WMI provider subsystem installed. Go into "Turn Windows Features on or off" to see what you're missing under Hyper-V.

Hi Dave,

Thanks for your reply. I checked services there are a couple of Hyper-V services that I tried to start but they did not start. And I didn't see any Hyper-V manager tool on the programs as well. How can I fix this problem?

Best regards.

You didn't do what I told you. "Services" is not "Turn Windows Features on or off". Type "Features" into the Window Search bar to find it.

I got; Hyper-V cannot be installed a hypervisor is already running. I think this may work for me;
