C#.Net Mvc运营监控，计算方法/接口/action/页面执行时间

1、建立一个TimingActionFilter过滤器

2、代码如下：

public class TimingActionFilter : ActionFilterAttribute     {         public override void OnActionExecuting(ActionExecutingContext filterContext)         {             GetTimer(filterContext, "action").Start();             base.OnActionExecuting(filterContext);         }         public override void OnActionExecuted(ActionExecutedContext filterContext)         {             GetTimer(filterContext, "action").Stop();             base.OnActionExecuted(filterContext);         }         public override void OnResultExecuted(ResultExecutedContext filterContext)         {             var renderTimer = GetTimer(filterContext, "render");             renderTimer.Stop();             var actionTimer = GetTimer(filterContext, "action");             if (actionTimer.ElapsedMilliseconds >= 100 || renderTimer.ElapsedMilliseconds >= 100)             {                 LogHelper.WriteLog("运营监控(" + filterContext.RouteData.Values["controller"] + ")", String.Format(                         "【{0}】-【{1}】,执行:{2}ms,渲染:{3}ms",                         filterContext.RouteData.Values["controller"],                         filterContext.RouteData.Values["action"],                         actionTimer.ElapsedMilliseconds,                         renderTimer.ElapsedMilliseconds                     ));             }             base.OnResultExecuted(filterContext);         }         public override void OnResultExecuting(ResultExecutingContext filterContext)         {             GetTimer(filterContext, "render").Start();             base.OnResultExecuting(filterContext);         }         private Stopwatch GetTimer(ControllerContext context, string name)         {             string key = "__timer__" + name;             if (context.HttpContext.Items.Contains(key))             {                 return (Stopwatch)context.HttpContext.Items[key];             }             var result = new Stopwatch();             context.HttpContext.Items[key] = result;             return result;         }     }

其中LogHelper.WriteLog是我的写日志文件通用类，，修改成你自己的即可。

3、给controller或action加上特性

4、执行时间或渲染时间大于100ms会被记录下来
