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;
 // 2048
   foreach (var o in searcher1.Get())
capacity += (double)Convert.ToUInt64(o[PROPERTY_CAPACITY]) / (double)(1024 * 1024);
                        foreach (var o in searcher2.Get())
                            free += (double)Convert.ToUInt64(o[PROPERTY_AVAILABLE_BYTES]) / (double)(1024 * 1024);
                        foreach (var o in searcher3.Get())
                        {
                            if (o["LoadPercentage"] != null)
                            {
                                cpu = long.Parse(o["LoadPercentage"].ToString());
                            }
                            else {
                                cpu = 0;
                            }
                        }

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 > 1)
            {
                budiler.AppendLine(s);
            }
            this.textBox1.Text = budiler.ToString();
            num++;
        }

 暂时就到这儿了。
