1. Use WMI to create connection to the computer passing username and password. Once the connection is created,  query the CPU& memory by passing the query, similar as SQL.  This way can get CPU & memory for remote PC and local PC. For example:

System.Management.ConnectionOptions Conn = new ConnectionOptions();

Conn.Username = mpusername;

Conn.Password = mppwd;

string scopestring = "//" + mpserver + "/root/cimv2";

System.Management.ManagementScope Ms = new ManagementScope(scopestring);

Ms.Connect();

mos.Scope = Ms;

ObjectQuery oq = new ObjectQuery();

oq.QueryString = "select * from Win32_Processor";

mos.Query = oq;

ManagementObjectCollection moc = mos.Get();

内存这块花了比较多的时间，之前的对象已经过期，不能使用了，最后找到这个类“Win32_PerfRawData_PerfOS_Memory”

ManagementObjectCollection mcr = mcp.getQueryResult("select * from Win32_ComputerSystem");
           
           foreach (ManagementObject mo in mcr)
           {
               if (mo["TotalPhysicalMemory"] != null)
               {
                   totalm = long.Parse(mo["TotalPhysicalMemory"].ToString());
               }
           }
           ManagementObjectCollection moc = mcp.getQueryResult("select * from Win32_PerfRawData_PerfOS_Memory");
           foreach (ManagementObject mo in moc)
           {
               string avilable = mo.GetPropertyValue("AvailableBytes").ToString();
               avilablem = long.Parse(avilable);
           }

2. Get local server’s CPU and momory information passing the WMI classes, such as “Win32_Processor”， “Win32_OperatingSystem”

ManagementClass mc = new ManagementClass("Win32_OperatingSystem");

ManagementObjectCollection moc = mc.GetInstances();

3. Use performance counter to get performance data passing the performance counter name, such as monitor.PerformanceCounterFun("Processor", "_Total", "% Processor Time"). Normally we shoud get performance counter data several times, then use the average values.
