How to get power consumption of My Networks All Computers?

Hi;

This is real question : i am working a company. There are 200-300 computer in Network. I want to get Power consumption of each by each all computers.

Result must be:

192.168.1.210 :  120 kw/s
192.168.1.211 : 116 kw/s
182.168.1.212 : 123 kw/s

How to do it?

There is nothing in any of my 25 computers that will give you that thru a program.  You will have to go measure each and every one of them.  Remember to include the monitors for each one.

You would have to have a device to measure power consumption, such as the kill a watt,report in to a server the power usage, and then have it mapped out as to which unit is measuring which computer. Using MAC address would be more effective since that typically does not change, where as IPs frequently can.

However, this will be prohibitively expensive. There are some premade devices, such as the AlertMe, which can do what you want (~$40 per plug, plus the base station), however they're not designed for the scale that you're needing it for. Many people have modified Killawatts to report usage over networks, but that would cost roughly $60 a unit plus your time in doing the needed work. You're basically talking thousands of dollars for the hardware alone.

You can read the WMI information, refer to http://bytes.com/topic/c-sharp/answers/573946-query-power-consumption for sample code in C#. However not every hardware support it. Only high end servers will.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thanks everyBody;

But  i can not  use any device . i want to calculate electiricity or power measuring via ip?  @raysonlee i read it but not working ...

Does your PC support the function? Or there is problem with the sample code?

You can run this vbscript in your PC and see whether the results returned properly.

Ok i want to develop a C#program , is there a simple way? Why below codes returns 0 value?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Management;
using System.Management.Instrumentation;

[assembly: WmiConfiguration(@"root\cimv2", HostingModel = ManagementHostingModel.LocalSystem)]

namespace VoltageConsumptions
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                ManagementObjectSearcher searcher = new ManagementObjectSearcher(@"root\cimv2","SELECT * FROM Win32_VoltageProbe");

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_VoltageProbe instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("CurrentReading: {0}", queryObj["CurrentReading"]);
                    Console.WriteLine("Tolerance: {0}", queryObj["Tolerance"]);

                } 
                Console.ReadKey();
            }
            catch (ManagementException e)
            {

            }
        }
    }

Try use the sample in here http://www.dreamincode.net/forums/topic/42934-using-wmi-class-in-c%23/ to test the standard values. If they are OK, change the parameters to get Voltage and see if the problem is in the code or PC.
