测量中调用时间ASP.NET MVC控制器动作 [英] Measure Time Invoking ASP.NET MVC Controller Actions

问题描述

一个MVC 4应用程序的一些用户遇到零星缓慢。 presumably不是每个用户每次发生在他们身上的时间报道了这个问题。

Some users of an MVC 4 app are experiencing sporadic slowness. Presumably not every user reports that problem every time it happens to them.

我的想法是衡量每个控制器动作所花费的时间和日志超过prescribed时间，以方便进一步的分析行动调用的细节（在排除或排除服务器/ code问题）。

My thought is to measure the time spent in each controller action and log details of action invocations that exceed a prescribed time to facilitate further analysis (to rule in or rule out a server/code issue).

有钩在执行这样的测量，因此，我能避免增加仪表code到每个操作方便的方法？我不是目前使用国际奥委会的这个项目，并会毫不犹豫地介绍它正好解决了这一问题。

Is there a convenient way to hook in to perform such measurements so that I can avoid adding instrumentation code to each action? I'm not currently using IOC for this project and would hesitate to introduce it just to solve this issue.

有没有更好的方式来处理此类问题？

Is there a better way to tackle this type of problem?

推荐答案

您可以创建一个全球行动过滤器？事情是这样的：

Could you create a global action filter? Something like this:

public class PerformanceTestFilter : IActionFilter
{
    private Stopwatch stopWatch = new Stopwatch();

    public void OnActionExecuting(ActionExecutingContext filterContext)
    {
        stopWatch.Reset();
        stopWatch.Start();
    }

    public void OnActionExecuted(ActionExecutedContext filterContext)
    {
        stopWatch.Stop();
        var executionTime = stopWatch.ElapsedMilliseconds;
        // Do something with the executionTime
    }
}

然后将其添加到`的Application_Start（）你的 GlobalFilters 集

GlobalFilters.Filters.Add(new PerformanceTestFilter());

您可以获取有关从 filterContext 参数被测试的控制器的细节。

You can get details about the controller being tested from the filterContext parameter.

更新

直接添加过滤器的 GlobalFilters 集合将创建过滤器的所有行动的一个实​​例。此，当然也不会定时并发请求工作。要为每个操作创建一个新的实例，创建一个过滤器供应商：

Adding the filter to the GlobalFilters collection directly will create a single instance of the filter for all actions. This, of course, will not work for timing concurrent requests. To create a new instance for each action, create a filter provider:

public class PerformanceTestFilterProvider : IFilterProvider
{
    public IEnumerable<Filter> GetFilters(ControllerContext controllerContext, ActionDescriptor actionDescriptor)
    {
        return new[] {new Filter(new PerformanceTestFilter(), FilterScope.Global, 0)};
    }
}

然后，而不是直接添加过滤器，而加入的Application_Start（）过滤器提供商：

FilterProviders.Providers.Add(new PerformanceTestFilterProvider());
