何為心跳監控系統？

故名思義，就是監控某個或某些個程序的運行狀態，就好比醫院里面的心跳監視儀一樣，能夠隨時顯示病人的心跳情況。

心跳監控的目的是什么？

與醫院里面的心跳監視儀目的類似，監控程序運行狀態，一旦出現問題（比如：一些自動運行的服務、程序等突然停止運行了），那么心跳監控系統就能“感知到”并及時的顯示在監控界面上，同時可以通過微信、短信告之相關的人員，以便他們及時處理程序異常，從而避免一些自動運行的服務、程序等突然停止運行而造成的一系列損失

心跳監控系統實現的思路是怎樣的？

核心技術：WCF的雙工通訊

實現步驟：

1.定義WCF的服務契約接口以及回調接口，服務方法主要包括：Start（被監控的程序啟動時調用，即通知監控系統，我已經啟動了）、Stop（被監控的程序停止時調用，即通知監控系統，我已經停止了）、ReportRunning（被監控的程序運行中定時調用，即通知監控系統，我是正常的并在運行中，同時還起到檢測監控系統是否在運行的一個功能，一舉兩得），回調服務方法應有：Listen（這個是給監控系統主動去定時回調被監控的程序（心跳），如果被監控的程序能正常的返回狀態，那么就是正常的，否則有可能已經“死了”，這時監控系統就需要按照預設指令作出相應的操作，比如：監控主界面顯示異常的程序，同時發送異常通知消息給相關人員）

2.建立一個心跳監控系統Winform項目，并實現WCF服務，即集成實現WCF服務宿主程序，同時每一個WCF服務方法均需關聯界面，即：程序啟動了、停止了、運行中均會在界面實時顯示出來或做一些實時統計；

3.其它被監控的程序（指自動運行的服務、程序等）需要集成實現WCF回調接口及開啟WCF服務通訊的功能；

心跳監控系統的運行順序是怎樣的？如何保證監控方與被監控方實時不間斷通訊？

運行順序：

1.開啟心跳監控系統（即：同時開啟WCF服務宿主程序），確保監控服務正常運行；

2.開啟其它被監控的程序，確保開啟客戶端與監控系統的WCF雙工通訊服務正常；

注意：一定要先開啟心跳監控系統，否則其它被監控的程序因無法與監控系統的WCF雙工通訊服務正常連接而報錯或多次嘗試重連；

保證監控方與被監控方實時不間斷通訊：

在保證按照上面所說的運行順序依次開啟心跳監控系統，再開啟其它被監控的程序，正常建立一次通訊后，后續只要任何一方出現通訊中斷，均會自動嘗試重連（主要是客戶端重連，心跳監控系統除非停止運行，否則不會中斷，若因停止運行造成雙方通訊中斷，只需重啟心跳監控系統即可）

通訊模式：

推模式：被監控的程序通過主動的調用WCF服務方法：Start、Stop、ReportRunning 向心跳監控系統告之運行狀態，若通訊失敗，則自動嘗試重連，直至連接成功；

拉模式：心跳監控系統主動回調Listen方法，向被監控的程序索取運行狀態，若通訊失敗，則會在指定時間內多次重試回調客戶端，若客戶端在規定的時間范圍內仍無法返回消息，則視為客戶端異常，那么心跳監控系統則會進行異常的處理；

實現源代碼：

ProgramMonitor.Core 類庫項目：主要是定義WCF服務的相關接口以及實現回調的接口（因為每個客戶端都需實現一遍回調接口，故統一實現，客戶端集成后直接可以用，簡化集成客戶端的開發成本），心跳監控系統及需要被監控的程序均需要依賴該DLL；

ProgramMonitor WINFORM項目：心跳監控系統

整個解決方案如下圖示：

注：由于源代碼相對較多，故不再一一說明，只對重點的代碼作解釋

ProgramMonitor.Core

IListenService：（心跳監控WCF服務契約接口）

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel;namespace ProgramMonitor.Core {[ServiceContract(Namespace = "http://www.zuowenjun.cn", SessionMode = SessionMode.Required, CallbackContract = typeof(IListenCall))]public interface IListenService{[OperationContract(IsOneWay = true)]void Start(ProgramInfo programInfo);[OperationContract(IsOneWay = true)]void Stop(string programId);[OperationContract(IsOneWay = true)]void ReportRunning(ProgramInfo programInfo);} }

IListenCall：（監聽回調服務接口，主用被心跳監控系統調用）

using System; using System.Collections.Generic; using System.Linq; using System.ServiceModel; using System.Text;namespace ProgramMonitor.Core {public interface IListenCall{[OperationContract]int Listen(string programId);} }

ProgramInfo：（程序信息類，主要用于獲取被監控程序的基本信息）

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.Runtime.Serialization;namespace ProgramMonitor.Core {[DataContract(Namespace = "http://www.zuowenjun.cn")]public class ProgramInfo{public ProgramInfo(){}[DataMember]public string Id { get; internal set; }[DataMember]public string Name { get; set; }[DataMember]public string Version { get; set; }[DataMember]public string InstalledLocation { get; set; }[DataMember]public string Description { get; set; }private int runState = -1;/// <summary>/// 運行狀態，-1:表示停止，0表示啟動，1表示運行中/// </summary>[DataMember]public int RunState{get{return runState;}set{this.UpdateStateTime = DateTime.Now;if (value < 0){runState = -1;this.StopTime = this.UpdateStateTime;}else if (value == 0){runState = 0;this.StartTime = this.UpdateStateTime;}else{runState = 1;}}}[DataMember]public DateTime UpdateStateTime { get; private set; }[DataMember]public DateTime StartTime { get; private set; }[DataMember]public DateTime StopTime { get; private set; }} }

?ListenClient：（監聽客戶端類，實現WCF回調服務接口，主要用于被監控的程序）

using System; using System.Collections.Generic; using System.Diagnostics; using System.IO; using System.Linq; using System.Security.Cryptography; using System.ServiceModel; using System.ServiceModel.Description; using System.Text;namespace ProgramMonitor.Core {public class ListenClient : IListenCall{private static object syncObject = new object();private static ListenClient instance = null;private ProgramInfo programInfo = null;private string serviceHostAddr = null;private int autoReportRunningInterval = 300;private DuplexChannelFactory<IListenService> listenServiceFactory = null;private IListenService proxyListenService = null;private System.Timers.Timer reportRunningTimer = null;private ListenClient(ProgramInfo programInfo, string serviceHostAddr = null, int autoReportRunningInterval = 300){programInfo.Id = CreateProgramId();this.programInfo = programInfo;this.serviceHostAddr = serviceHostAddr;if (autoReportRunningInterval >= 60) //最低1分鐘的間隔{this.autoReportRunningInterval = autoReportRunningInterval;}BuildAutoReportRunningTimer();}private void BuildAutoReportRunningTimer(){reportRunningTimer = new System.Timers.Timer(autoReportRunningInterval * 1000);reportRunningTimer.Elapsed += (s, e) =>{ReportRunning();};}private void BuildListenClientService(){if (listenServiceFactory == null){if (string.IsNullOrEmpty(serviceHostAddr)){serviceHostAddr = System.Configuration.ConfigurationManager.AppSettings["ServiceHostAddr"];}InstanceContext instanceContext = new InstanceContext(instance);NetTcpBinding binding = new NetTcpBinding();binding.ReceiveTimeout = new TimeSpan(0, 5, 0);binding.SendTimeout = new TimeSpan(0, 5, 0);Uri baseAddress = new Uri(string.Format("net.tcp://{0}/ListenService", serviceHostAddr));listenServiceFactory = new DuplexChannelFactory<IListenService>(instanceContext, binding, new EndpointAddress(baseAddress));}proxyListenService = listenServiceFactory.CreateChannel();}public static ListenClient GetInstance(ProgramInfo programInfo, string serviceHostAddr = null, int autoReportRunningInterval = 300){if (instance == null){lock (syncObject){if (instance == null){instance = new ListenClient(programInfo, serviceHostAddr, autoReportRunningInterval);instance.BuildListenClientService();}}}return instance;}public void ReportStart(){proxyListenService.Start(programInfo);reportRunningTimer.Start();}public void ReportStop(){proxyListenService.Stop(programInfo.Id);reportRunningTimer.Stop();}public void ReportRunning(){try{proxyListenService.ReportRunning(programInfo);}catch{BuildListenClientService();}}int IListenCall.Listen(string programId){if (programInfo.Id.Equals(programId, StringComparison.OrdinalIgnoreCase)){if (programInfo.RunState >= 0){return 1;}}return -1;}private string CreateProgramId(){Process currProcess = Process.GetCurrentProcess();int procCount = Process.GetProcessesByName(currProcess.ProcessName).Length;string currentProgramPath = currProcess.MainModule.FileName;return GetMD5HashFromFile(currentProgramPath) + "_" + procCount;}private string GetMD5HashFromFile(string fileName){try{byte[] hashData = null;using (FileStream fs = new FileStream(fileName, System.IO.FileMode.Open, FileAccess.Read)){MD5 md5 = new MD5CryptoServiceProvider();hashData = md5.ComputeHash(fs);fs.Close();}StringBuilder sb = new StringBuilder();for (int i = 0; i < hashData.Length; i++){sb.Append(hashData[i].ToString("x2"));}return sb.ToString();}catch (Exception ex){throw new Exception("GetMD5HashFromFile Error:" + ex.Message);}}}}

這里特別說一下：CreateProgramId方法，因為心跳監控系統主要是依據ProgramId來識別每個不同的程序，故ProgramId非常重要，而我這里采用的是文件的 MD5值+進程數作為ProgramId，有些人可能要問，為什么要加進程數呢？原因很簡單，因為有些程序是允許開啟多個的實例的，如果不加進程數，那么心跳監控系統就無法識別多個同一個程序到底是哪個。

?ProgramMonitor

ListenService：（WCF心跳監控服務接口實現類）

被監控的客戶端程序集成WCF監聽客戶端很簡單，只需引用ProgramMonitor.Core，然后實例化ListenClient，最后就可以通過該ListenClient與心跳監控系統進行雙工通訊，在此就不貼出源代碼了。

上述代碼中還有用到兩個類：

DataAccess：數據訪問類，這個我之前的文章有介紹，詳見：DataAccess通用數據庫訪問類，簡單易用，功能強悍

WeChat：微信企業號發送消息類，注意是微信企業號，不是公眾號，這里我也貼出源代碼來，供大家了解：

using Newtonsoft.Json; using Newtonsoft.Json.Linq; using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Net; using System.Text; using System.Web;namespace ProgramMonitor.Service {public class WeChat{private readonly string _url = null;private readonly string _corpid = null;private readonly string _secret = null;public WeChat(){_url = "https://qyapi.weixin.qq.com/cgi-bin";_corpid = "CorpID是企業號的標識，每個企業號擁有一個唯一的CorpID";_secret = "secret是管理組憑證密鑰，系統管理員在企業號管理后臺創建管理組時，企業號后臺為該管理組分配一個唯一的secret";}public string GetToken(string url_prefix = "/"){string urlParams = string.Format("corpid={0}&corpsecret={1}", HttpUtility.UrlEncodeUnicode(_corpid), HttpUtility.UrlEncodeUnicode(_secret));string url = _url + url_prefix + "gettoken?" + urlParams;string result = HttpGet(url);var content = JObject.Parse(result);return content["access_token"].ToString();}public JObject PostData(dynamic data, string url_prefix = "/"){string dataStr = JsonConvert.SerializeObject(data);string url = _url + url_prefix + "message/send?access_token=" + GetToken();string result = HttpPost(url, dataStr);return JObject.Parse(result);}public JObject SendMessage(string touser, string message){var data = new { touser = touser, toparty = "1", msgtype = "text", agentid = "2", text = new { content = message }, safe = "0" };var jResult = PostData(data);return jResult;}private string HttpPost(string Url, string postDataStr){HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);request.Method = "POST";request.ContentType = "application/x-www-form-urlencoded";byte[] data = Encoding.UTF8.GetBytes(postDataStr);request.ContentLength = data.Length;Stream myRequestStream = request.GetRequestStream();myRequestStream.Write(data, 0, data.Length);myRequestStream.Close();HttpWebResponse response = (HttpWebResponse)request.GetResponse();Stream myResponseStream = response.GetResponseStream();StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);string retString = myStreamReader.ReadToEnd();myStreamReader.Close();myResponseStream.Close();return retString;}public string HttpGet(string Url, string urlParams = null){HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (string.IsNullOrEmpty(urlParams) ? "" : "?") + urlParams);request.Method = "GET";request.ContentType = "text/html;charset=UTF-8";HttpWebResponse response = (HttpWebResponse)request.GetResponse();Stream myResponseStream = response.GetResponseStream();StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);string retString = myStreamReader.ReadToEnd();myStreamReader.Close();myResponseStream.Close();return retString;}} }

具體的關于微信企業號開發文檔，可參見：http://qydev.weixin.qq.com/wiki/index.php

最后的效果如下：

心跳監控程序監控效果：

手機收到異常消息：

? （《-這是企業號發出的消息） ? ? ? ? ? ? ? ? ? ?（《-這里短信消息，當然發短信是我公司的平臺接口發出的，發短信是需要RMB的，故不建議）

?

好了本文就到此結束，可能功能相對簡單，還有一些不足，歡迎大家評論交流，謝謝！
