How to get remote server CPU usage in same network.

private PerformanceCounter cpuCounter = null;
cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total", machineName);
                //ramCounter = new PerformanceCounter("Memory", "Available MBytes", String.Empty, machineName);
                ramCounter = new PerformanceCounter("Memory", "% Committed Bytes In Use", String.Empty, machineName);
                pageCounter = new PerformanceCounter("Paging File", "% Usage", "_Total", machineName);
                // there can be multiple network interfaces
                nicCounters = GetNICCounters();
                // for each nic card, create a corresponding status bar label
                for (int i = 0; i < nicCounters.Length; i++)
                { ssStatusBar.Items.Add(GetNICLabel(nicCounters[i], i)); }
