log4net 记录MVC监控日志
由于MVC自身的特点，可以让我们记录每一个Controller下Action的执行时间以及View视图渲染完成的时间，本文采用log4net记录MVC每个Action的执行时间和View视图渲染完成时间，以及请求Action时post或get的数据。这样通过日志记录的时间方便我们定位哪一个Action和View执行的时间过长，进而采取优化的手段。
监控日志监控的指标如下图
监控程序实现
改监控程序主要继承ActionFilterAttribute类，并重写其中的OnActionExecuted、OnActionExecuting、OnResultExecuted、OnResultExecuting几个方法实现。
1、监控日志对象
/// <summary> /// 监控日志对象 /// </summary> public class MonitorLog { public string ControllerName { get; set; } public string ActionName { get; set; } public DateTime ExecuteStartTime { get; set; } public DateTime ExecuteEndTime { get; set; } /// <summary> /// Form 表单数据 /// </summary> public NameValueCollection FormCollections { get; set; } /// <summary> /// URL 参数 /// </summary> public NameValueCollection QueryCollections { get; set; } /// <summary> /// 监控类型 /// </summary> public enum MonitorType { Action = 1, View = 2 } /// <summary> /// 获取监控指标日志 /// </summary> /// <param name="mtype"></param> /// <returns></returns> public string GetLoginfo(MonitorType mtype = MonitorType.Action) { string ActionView = "Action执行时间监控："; string Name = "Action"; if (mtype == MonitorType.View) { ActionView = "View视图生成时间监控："; Name = "View"; } string Msg = @" {0} ControllerName：{1}Controller {8}Name:{2} 开始时间：{3} 结束时间：{4} 总 时 间：{5}秒 Form表单数据：{6} URL参数：{7} "; return string.Format(Msg, ActionView, ControllerName, ActionName, ExecuteStartTime, ExecuteEndTime, (ExecuteEndTime - ExecuteStartTime).TotalSeconds, GetCollections(FormCollections), GetCollections(QueryCollections), Name); } /// <summary> /// 获取Post 或Get 参数 /// </summary> /// <param name="Collections"></param> /// <returns></returns> public string GetCollections(NameValueCollection Collections) { string Parameters = string.Empty; if (Collections == null || Collections.Count == 0) { return Parameters; } foreach (string key in Collections.Keys) { Parameters += string.Format("{0}={1}&", key, Collections[key]); } if (!string.IsNullOrWhiteSpace(Parameters) && Parameters.EndsWith("&")) { Parameters = Parameters.Substring(0, Parameters.Length - 1); } return Parameters; } }
2、监控类
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false)] public class StatisticsTrackerAttribute : ActionFilterAttribute,IExceptionFilter { private readonly string Key = "_thisOnActionMonitorLog_"; #region Action时间监控 public override void OnActionExecuting(ActionExecutingContext filterContext) { MonitorLog MonLog = new MonitorLog(); MonLog.ExecuteStartTime = Convert.ToDateTime(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss.ffff", DateTimeFormatInfo.InvariantInfo)); MonLog.ControllerName = filterContext.RouteData.Values["controller"] as string; MonLog.ActionName = filterContext.RouteData.Values["action"] as string; filterContext.Controller.ViewData[Key] = MonLog; } public override void OnActionExecuted(ActionExecutedContext filterContext) { MonitorLog MonLog = filterContext.Controller.ViewData[Key] as MonitorLog; MonLog.ExecuteEndTime = DateTime.Now; MonLog.FormCollections = filterContext.HttpContext.Request.Form;//form表单提交的数据 MonLog.QueryCollections = filterContext.HttpContext.Request.QueryString;//Url 参数 LoggerHelper.Monitor(MonLog.GetLoginfo()); } #endregion #region View 视图生成时间监控 public override void OnResultExecuting(ResultExecutingContext filterContext) { MonitorLog MonLog = filterContext.Controller.ViewData[Key] as MonitorLog; MonLog.ExecuteStartTime = DateTime.Now; } public override void OnResultExecuted(ResultExecutedContext filterContext) { MonitorLog MonLog = filterContext.Controller.ViewData[Key] as MonitorLog; MonLog.ExecuteEndTime = DateTime.Now; LoggerHelper.Monitor(MonLog.GetLoginfo(MonitorLog.MonitorType.View)); filterContext.Controller.ViewData.Remove(Key); } #endregion #region 错误日志 public void OnException(ExceptionContext filterContext) { if (!filterContext.ExceptionHandled) { string ControllerName =string.Format("{0}Controller",filterContext.RouteData.Values["controller"] as string); string ActionName = filterContext.RouteData.Values["action"] as string; string ErrorMsg = string.Format("在执行 controller[{0}] 的 action[{1}] 时产生异常", ControllerName, ActionName); LoggerHelper.Error(ErrorMsg, filterContext.Exception); } } #endregion }
3、引用监控
我们可以在每个Controller类上或Action上直接引用 [StatisticsTracker]即可完成对该Controller或Action的监控。
我们也可以在FilterConfig.cs中注册全局监控，这样我们就可以监控每一个Controller中的Action，代码如下：
public class FilterConfig { public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleErrorAttribute()); //监控引用 filters.Add(new StatisticsTrackerAttribute()); } }
LoggerHelper
log文件的记录采用log4net，log4net是.Net下一个非常优秀的开源日志记录组件。log4net记录日志的功能非常强大。具体配置如下。
1、log4net配置文件
log4Net的配置文件名称为log4net.config，具体配置如下。
<?xml version="1.0"?><configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <!--错误日志--> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value=http://www.mamicode.com/"log\\LogError\\"/> <appendToFile value=http://www.mamicode.com/"true"/> <rollingStyle value=http://www.mamicode.com/"Date"/> <datePattern value=http://www.mamicode.com/"yyyy\\yyyyMM\\yyyyMMdd‘.txt‘"/> <staticLogFileName value=http://www.mamicode.com/"false"/> <param name="MaxSizeRollBackups" value=http://www.mamicode.com/"100"/> <layout type="log4net.Layout.PatternLayout"> <!--每条日志末尾的文字说明--> <!--输出格式--> <!--样例：2008-03-26 13:42:32,111 [10] INFO Log4NetDemo.MainClass [(null)] - info--> <conversionPattern value=http://www.mamicode.com/"%newline %n记录时间：%date %n线程ID:[%thread] %n日志级别： %-5level %n错误描述：%message%newline %n"/> </layout> </appender> <!--Info日志--> <appender name="InfoAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value=http://www.mamicode.com/"Log\\LogInfo\\" /> <param name="AppendToFile" value=http://www.mamicode.com/"true" /> <param name="MaxFileSize" value=http://www.mamicode.com/"10240" /> <param name="MaxSizeRollBackups" value=http://www.mamicode.com/"100" /> <param name="StaticLogFileName" value=http://www.mamicode.com/"false" /> <param name="DatePattern" value=http://www.mamicode.com/"yyyy\\yyyyMM\\yyyyMMdd‘.txt‘" /> <param name="RollingStyle" value=http://www.mamicode.com/"Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value=http://www.mamicode.com/"%newline %n记录时间：%date %n线程ID:[%thread] %n日志级别： %-5level %n日志描述：%message%newline %n"/> </layout> </appender> <!--监控日志--> <appender name="MonitorAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value=http://www.mamicode.com/"Log\\LogMonitor\\" /> <param name="AppendToFile" value=http://www.mamicode.com/"true" /> <param name="MaxFileSize" value=http://www.mamicode.com/"10240" /> <param name="MaxSizeRollBackups" value=http://www.mamicode.com/"100" /> <param name="StaticLogFileName" value=http://www.mamicode.com/"false" /> <param name="DatePattern" value=http://www.mamicode.com/"yyyy\\yyyyMM\\yyyyMMdd‘.txt‘" /> <param name="RollingStyle" value=http://www.mamicode.com/"Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value=http://www.mamicode.com/"%newline %n记录时间：%date %n线程ID:[%thread] %n日志级别： %-5level %n跟踪描述：%message%newline %n"/> </layout> </appender> <!--Error日志--> <logger name="logerror"> <level value=http://www.mamicode.com/"ERROR" /> <appender-ref ref="RollingLogFileAppender" /> </logger> <!--Info日志--> <logger name="loginfo"> <level value=http://www.mamicode.com/"INFO" /> <appender-ref ref="InfoAppender" /> </logger> <!--监控日志--> <logger name="logmonitor"> <level value=http://www.mamicode.com/"Monitor" /> <appender-ref ref="MonitorAppender" /> </logger> </log4net></configuration>
2、注册log4net配置文件
在Global.asax中注册log4net配置文件，代码如下
protected void Application_Start() { //注册 log4net log4net.Config.XmlConfigurator.Configure( new System.IO.FileInfo(AppDomain.CurrentDomain.BaseDirectory + "\\Config\\log4net.config") ); AreaRegistration.RegisterAllAreas(); WebApiConfig.Register(GlobalConfiguration.Configuration); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); }
3、LoggerHelper.cs
using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace Monitor.Models.ActionFilters{ public class LoggerHelper { static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo"); static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror"); static readonly log4net.ILog logmonitor = log4net.LogManager.GetLogger("logmonitor"); public static void Error(string ErrorMsg, Exception ex = null) { if (ex != null) { logerror.Error(ErrorMsg, ex); } else { logerror.Error(ErrorMsg); } } public static void Info(string Msg) { loginfo.Info(Msg); } public static void Monitor(string Msg) { logmonitor.Info(Msg); } }}
4.log4net日志生成的文件目录结构如下图
目录结构我们区分开了错误日志、Info日志、监控日志，并且会按照日期生成日志，方便我们查看。
