由缓慢的客户端引起的BadHttpRequestException出现在我的应用程序见解中

问题描述 投票：0回答：1

我的API的一个调用者有时会遇到一些性能问题，这些问题最终会使他们的CPU利用率达到100％，并且我的API由于请求超时而拒绝了他们的某些调用（HTTP 408）。这对我来说很好，因为我认为拒绝来电是一种保护。但是，由于超时被作为异常进行跟踪，因此它还会在Application Insights中触发警报。请求是POST。

我该怎么做才能防止这种情况？我研究了Application Insights的过滤配置，但是找不到任何可以过滤此特定异常的内容。正因为如此，我不想过滤太多的日志条目。

另外，我可以在Stacktrace中看到Swashbuckle。重新排列ConfigureServices方法中的内容是否有帮助？当前在AddApplicationInsightsTelemetry之后配置了Swashbuckle。

我使用在.NET 4.7.2上运行的ASP.NET Core 2.2。通过Microsoft.ApplicationInsights.AspNetCore

添加了Application Insights。

要过滤这种类型的异常"Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException"，可以使用ITelemetryProcessor。

在您的.net核心项目中，添加一个名为MyTelemetryProcessor的类，以下是该类的详细信息：

public class MyTelemetryProcessor: ITelemetryProcessor
{
    private ITelemetryProcessor Next { get; set; }

    public MyTelemetryProcessor(ITelemetryProcessor next)
    {
        this.Next = next;
    }

    public void Process(ITelemetry telemetry)
    {

        ExceptionTelemetry err1 = telemetry as ExceptionTelemetry;

        //you can use exception type or the error message to filter
        if(err1 !=null && err1.Exception.GetType().ToString().Contains("the exception type you want to filter"))
        {
            return;
        }

        if (err1 == null)
        {
            this.Next.Process(telemetry);

        }

        if (err1 != null)
        {
            this.Next.Process(err1);
        }
    }
}

然后在Startup.cs-> ConfigureServices（）方法中，添加以下代码：

services.AddApplicationInsightsTelemetry();
services.AddApplicationInsightsTelemetryProcessor<MyTelemetryProcessor>();
