缓慢的客户端导致的 BadHttpRequestException 出现在我的应用程序洞察中

Question

我的 API 的一个来电者有时会遇到一些性能问题，他们最终会达到 100% CPU 而我的 API 由于请求而拒绝了他们的一些呼叫超时（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，它还会触发 Application Insights 中的警报，因为超时被作为异常进行跟踪。请求是 POST。

我能做些什么来防止这种情况发生？我查看了 Application Insights 的过滤配置，但找不到任何可以过滤此特定异常的内容。我不想因为这个过滤太多的日志条目。

此外，我可以在 Stacktrace 中看到 Swashbuckle。在我的 ConfigureServices 方法中重新排列一些东西会有帮助吗？ Swashbuckle 当前配置在 AddApplicationInsightsTelemetry.

之后

我在 .NET 4.7.2 上使用 ASP.NET Core 2.2，运行。通过 Microsoft.ApplicationInsights.AspNetCore

添加 Application Insights

Answer 1

要过滤此类异常 "Microsoft.AspNetCore.Server.Kestrel.Core.BadHttpRequestException"，您可以使用 ITelemetryProcessor.

在你的.net core项目中，添加一个名为MyTelemetryProcessor的class，下面是这个class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，添加如下代码：

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