页面生成时间 - ASP.Net MVC

Question

我正在寻找一种方法来跟踪服务器生成一个页面需要多长时间。我知道我可以使用跟踪来跟踪这个，但我需要一种方法来显示每页。

它的ASP.Net MVC 2

没错的Derin建议是标准的方式做到这一点在ASP.NEt应用程序，我只想建议增加一个，如果因此它不会与非HTML响应的干扰：编辑：添加完整的实现离子

public class PerformanceMonitorModule : IHttpModule 
{ 

    public void Init(HttpApplication context) 
    { 
     context.PreRequestHandlerExecute += delegate(object sender, EventArgs e) 
     { 
      //Set Page Timer Star 
      HttpContext requestContext = ((HttpApplication)sender).Context; 
      Stopwatch timer = new Stopwatch(); 
      requestContext.Items["Timer"] = timer; 
      timer.Start(); 
      }; 
     context.PostRequestHandlerExecute += delegate(object sender, EventArgs e) 
     { 

      HttpContext httpContext = ((HttpApplication)sender).Context; 
      HttpResponse response = httpContext.Response; 
      Stopwatch timer = (Stopwatch)httpContext.Items["Timer"]; 
      timer.Stop(); 

      // Don't interfere with non-HTML responses 
      if (response.ContentType == "text/html") 
      { 
       double seconds = (double)timer.ElapsedTicks/Stopwatch.Frequency; 
       string result_time = string.Format("{0:F4} sec ", seconds); 
       RenderQueriesToResponse(response,result_time); 
      } 
     }; 
    } 
    void RenderQueriesToResponse(HttpResponse response, string result_time) 
    { 
     response.Write("<div style=\"margin: 5px; background-color: #FFFF00\""); 
     response.Write(string.Format("<b>Page Generated in "+ result_time)); 
     response.Write("</div>"); 
    } 
    public void Dispose() { /* Not needed */ } 
} 

，你还可以添加一些样式，...

记住注册的HttpModules里科WebConfig你的模块：

<add name="Name" type="namespace, dll"/>

这取决于你想包含这些信息的地方。例如，你可以写一个HTTP处理程序将显示</html>标签后的渲染时间：

public class RenderTimeModule : IHttpModule 
{ 
    public void Init(HttpApplication context) 
    { 
     context.BeginRequest += (sender, e) => 
     { 
      var watch = new Stopwatch(); 
      var app = (HttpApplication)sender; 
      app.Context.Items["Stopwatch"] = watch; 
      watch.Start(); 
     }; 

     context.EndRequest += (sender, e) => 
     { 
      var app = (HttpApplication)sender; 
      var watch = (Stopwatch)app.Context.Items["Stopwatch"]; 
      watch.Stop(); 
      var ts = watch.Elapsed; 
      string elapsedTime = String.Format("{0} ms", ts.TotalMilliseconds); 
      app.Context.Response.Write(elapsedTime); 
     }; 
    } 

    public void Dispose() 
    { 
    } 
} 

如果你想显示在HTML页面的中间位置渲染时间那么这个渲染时间将不占总页面渲染时间。

您可以实现它像一个ActionFilterAttribute

[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)] 
public class LoggingAttribute : ActionFilterAttribute 
{ 
    private readonly Stopwatch _sw; 

    public LoggingAttribute() 
    { 
     _sw = new Stopwatch(); 
    } 

    public override void OnActionExecuting(ActionExecutingContext filterContext) 
    { 
     _sw.Start(); 
     Debug.WriteLine("Beginning executing: " + GetControllerAndActionName(filterContext.ActionDescriptor)); 
    } 

    public override void OnActionExecuted(ActionExecutedContext filterContext) 
    { 
     _sw.Stop(); 
     var ms = _sw.ElapsedMilliseconds; 

     Debug.WriteLine("Finishing executing: " + GetControllerAndActionName(filterContext.ActionDescriptor)); 
     Debug.WriteLine("Time elapsed: "+ TimeSpan.FromMilliseconds(ms).TotalSeconds); 
    } 

    private string GetControllerAndActionName(ActionDescriptor actionDescriptor) 
    { 
     return actionDescriptor.ControllerDescriptor.ControllerName + " - " + actionDescriptor.ActionName; 
    } 
} 

装饰每个控制器或动作方法与它瞧，它吐奏在调试中的文本。

编辑：如果您想打印的页面上，可以将这个片段添加到OnActionExecuted方法

if(filterContext.Result is ViewResult) { //Make sure the request is a ViewResult, ie. a page 
    ((ViewResult) filterContext.Result).ViewData["ExecutionTime"] = ms; //Set the viewdata dictionary 
} 

现在你有executiontime保存在ViewData的，并且可以在页面访问它。我平时把它放在母版这样

<!-- The page took <%= ViewData["ExecutionTime"] %> ms to execute -->
