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

我这里有好几次执行时间7、800ms是因为每次重新生成项目,所以第一次会这么慢,这种不管它就是了:)
