C#实现对远程服务器的内存和CPU监控

C#实现对远程服务器的内存和CPU监控小记

1、  主要使用到的组件有System.Management.dll

2、  主要类为 ：ManagementScope

连接远程服务器示例代码：

 private const string PROPERTY_CAPACITY = "Capacity";
         private const string PROPERTY_AVAILABLE_BYTES = "AvailableBytes";
         private const string PROPERTY_PROCESS_ID = "ProcessId";
         private const string PROPERTY_PROCESS_NAME = "Name";
         private const string PROPERTY_WORKING_SET_SIZE = "WorkingSetSize";

 ConnectionOptions Conn = new ConnectionOptions();
                 //设定用于WMI连接操作的用户名
                 Conn.Username = "用户名";
                 //设定用户的口令
                 Conn.Password = "密码";
              ManagementScope   Ms = new         ManagementScope("\\\\ip\\root\\cimv2", Conn);
                 Ms.Connect();

具体查询举例：

 var query1 = new SelectQuery("SELECT * FROM Win32_PhysicalMemory");
  var query2 = new SelectQuery("SELECT * FROM Win32_PerfRawData_PerfOS_Memory");
   var query3 = new SelectQuery("SELECT * FROM Win32_Processor");
  var query4 = new SelectQuery("SELECT * FROM Win32_Process");

  var searcher1 = new ManagementObjectSearcher(Ms, query1);
  var searcher2 = new ManagementObjectSearcher(Ms, query2);
 var searcher3 = new ManagementObjectSearcher(Ms, query3);
 var searcher4 = new ManagementObjectSearcher(Ms, query4);

查询内存和CPU：

 var capacity = 0.0;
    var free = 0.0;
   var cpu = 0.0;
  //
    foreach (var o in searcher1.Get())
capacity += (double)Convert.ToUInt64(o[PROPERTY_CAPACITY]) / (double)( * );
                         foreach (var o in searcher2.Get())
                             free += (double)Convert.ToUInt64(o[PROPERTY_AVAILABLE_BYTES]) / (double)( * );
                         foreach (var o in searcher3.Get())
                         {
                             if (o["LoadPercentage"] != null)
                             {
                                 cpu = long.Parse(o["LoadPercentage"].ToString());
                             }
                             else {
                                 cpu = ;
                             }
                         }

举例远程重启某个进程（部分示例代码）：

 ConnectionOptions Conn = new ConnectionOptions();
             Conn.Username = userName; //设定用户的口令
             Conn.Password = pwd;
             Ms = new ManagementScope("\\\\" + ip + "\\root\\cimv2", Conn);
             Ms.Connect();
  ManagementClass processClass = new ManagementClass(Ms, new ManagementPath("Win32_Process"), null);
             //获得用来提供参数的对象
             ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
             //设定命令行参数
                 inParams["CommandLine"] = path;// @"需要启动的进程路径";
                 //执行程序
             ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);

Other、可以用程序操作批处理文件(.bat)来查询进程或者是关闭进程：

例如查询所有进程 ：tasklist /S ip /U 用户名 /P 密码

关闭某个进程：

taskkill  /S ip /U用户名/P 密码  /IM 需要关闭的进程名

部分示例代码：

 public delegate void DelReadStdOutput(string result);
         public delegate void DelReadErrOutput(string result);
         public event DelReadStdOutput ReadStdOutput;
         public event DelReadErrOutput ReadErrOutput;
 /// <summary>
         /// 注册事件
         /// </summary>
         private void Init()
         {
             ReadStdOutput += new DelReadStdOutput(ReadStdOutputAction);
             ReadErrOutput += new DelReadErrOutput(ReadErrOutputAction);

         }
 //----------------------部分实现代码==================
 using (p = new Process())
                 {

                     //pause --  停止
                     p.StartInfo.FileName = fileName;

                     p.StartInfo.UseShellExecute = false;
                     p.StartInfo.CreateNoWindow = true;

                     p.StartInfo.RedirectStandardError = true;
                     p.StartInfo.RedirectStandardInput = true;
                     p.StartInfo.RedirectStandardOutput = true;
                     p.EnableRaisingEvents = true;
                     p.Exited += new EventHandler(p_Exited);
                     p.ErrorDataReceived += new DataReceivedEventHandler(p_ErrorDataReceived);
                     p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);

                     p.Start();
                     //读取输出：
                     p.BeginErrorReadLine();
                     p.BeginOutputReadLine();
                     p.WaitForExit();
                 }

 void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
         {
             this.lab_tips.Text = "开始读取数据...读取时间可能有点长，请耐心等待！";
             if (e.Data != null)
             {
                 this.Invoke(ReadStdOutput, new object[] { e.Data });
             }
 }
 // 读取进程信息：
 public void ReadStdOutputAction(string s)
         {

             if (num > )
             {
                 budiler.AppendLine(s);
             }
             this.textBox1.Text = budiler.ToString();
             num++;
         }

暂时就到这儿了。
