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：

 1 private const string PROPERTY_CAPACITY = "Capacity";
 2         private const string PROPERTY_AVAILABLE_BYTES = "AvailableBytes";
 3         private const string PROPERTY_PROCESS_ID = "ProcessId";
 4         private const string PROPERTY_PROCESS_NAME = "Name";
 5         private const string PROPERTY_WORKING_SET_SIZE = "WorkingSetSize";
 6 
 7 
 8 ConnectionOptions Conn = new ConnectionOptions();
 9                 //设定用于WMI连接操作的用户名   
10                 Conn.Username = "用户名";
11                 //设定用户的口令
12                 Conn.Password = "密码";
13              ManagementScope   Ms = new         ManagementScope("\\ip\root\cimv2", Conn);
14                 Ms.Connect();

具体查询举例：

1 var query1 = new SelectQuery("SELECT * FROM Win32_PhysicalMemory");
2  var query2 = new SelectQuery("SELECT * FROM Win32_PerfRawData_PerfOS_Memory");
3   var query3 = new SelectQuery("SELECT * FROM Win32_Processor");
4  var query4 = new SelectQuery("SELECT * FROM Win32_Process");
5 
6  var searcher1 = new ManagementObjectSearcher(Ms, query1);
7  var searcher2 = new ManagementObjectSearcher(Ms, query2);
8 var searcher3 = new ManagementObjectSearcher(Ms, query3);
9 var searcher4 = new ManagementObjectSearcher(Ms, query4);

查询内存和CPU：

 1 var capacity = 0.0;
 2    var free = 0.0;
 3   var cpu = 0.0;
 4  // 2048
 5    foreach (var o in searcher1.Get())
 6capacity += (double)Convert.ToUInt64(o[PROPERTY_CAPACITY]) / (double)(1024 * 1024);
 7                         foreach (var o in searcher2.Get())
 8                             free += (double)Convert.ToUInt64(o[PROPERTY_AVAILABLE_BYTES]) / (double)(1024 * 1024);
 9                         foreach (var o in searcher3.Get())
10                         {
11                             if (o["LoadPercentage"] != null)
12                             {
13                                 cpu = long.Parse(o["LoadPercentage"].ToString());
14                             }
15                             else {
16                                 cpu = 0;
17                             }
18                         }

举例远程重启某个进程（部分示例代码）：

 1 ConnectionOptions Conn = new ConnectionOptions();
 2             Conn.Username = userName; //设定用户的口令
 3             Conn.Password = pwd;
 4             Ms = new ManagementScope("\\" + ip + "\root\cimv2", Conn);
 5             Ms.Connect();
 6  ManagementClass processClass = new ManagementClass(Ms, new ManagementPath("Win32_Process"), null);
 7             //获得用来提供参数的对象
 8             ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
 9             //设定命令行参数
10                 inParams["CommandLine"] = path;// @"需要启动的进程路径";
11                 //执行程序
12             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：

 1 public delegate void DelReadStdOutput(string result);
 2         public delegate void DelReadErrOutput(string result);
 3         public event DelReadStdOutput ReadStdOutput;
 4         public event DelReadErrOutput ReadErrOutput;
 5 /// <summary>
 6         /// 注册事件
 7         /// </summary>
 8         private void Init()
 9         {
10             ReadStdOutput += new DelReadStdOutput(ReadStdOutputAction);
11             ReadErrOutput += new DelReadErrOutput(ReadErrOutputAction);
12 
13         }
14 //----------------------部分实现代码==================
15 using (p = new Process())
16                 {
17  
18                     //pause --  停止
19                     p.StartInfo.FileName = fileName;
20                  
21                     p.StartInfo.UseShellExecute = false;
22                     p.StartInfo.CreateNoWindow = true;
23 
24                     p.StartInfo.RedirectStandardError = true;
25                     p.StartInfo.RedirectStandardInput = true;
26                     p.StartInfo.RedirectStandardOutput = true;
27                     p.EnableRaisingEvents = true;
28                     p.Exited += new EventHandler(p_Exited);
29                     p.ErrorDataReceived += new DataReceivedEventHandler(p_ErrorDataReceived);
30                     p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
31 
32                     p.Start();
33                     //读取输出：
34                     p.BeginErrorReadLine();
35                     p.BeginOutputReadLine();
36                     p.WaitForExit();
37                 }
38 
39 
40 void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
41         {
42             this.lab_tips.Text = "开始读取数据...读取时间可能有点长，请耐心等待！";
43             if (e.Data != null)
44             {
45                 this.Invoke(ReadStdOutput, new object[] { e.Data });
46             }
47 }
48 // 读取进程信息：
49 public void ReadStdOutputAction(string s)
50         {
51         
52             if (num > 1)
53             {
54                 budiler.AppendLine(s);
55             }
56             this.textBox1.Text = budiler.ToString();
57             num++;
58         }
