异常卷的异常增加(预览)Abnormal rise in exception volume (preview)

Application Insights 自动分析应用程序中引发的异常,并对异常遥测中的异常模式发出警告。Application Insights automatically analyzes the exceptions thrown in your application, and can warn you about unusual patterns in your exception telemetry.

此功能需要为应用配置异常报告,除此之外,不需要其他特殊步骤。This feature requires no special setup, other than configuring exception reporting for your app. 在应用生成足够多的异常遥测数据后,此功能会激活。It is active when your app generates enough exception telemetry.

何时会收到此类型的智能检测通知?When would I get this type of smart detection notification?

对比前面七天计算的基线,如果应用显示某个特殊类型的异常数在一天内异常增加,则可能会收到此类型的通知。You might get this type of notification if your app is exhibiting an abnormal rise in the number of exceptions of a specific type during a day, compared to a baseline calculated over the previous seven days.

收到通知是否意味着我的应用肯定有问题?Does my app definitely have a problem?

不是,通知并不意味着应用肯定有问题。No, a notification doesn't mean that your app definitely has a problem. 虽然异常数大量增加通常指示应用程序出现问题,但这些异常也可能是良性的并得到应用程序的正确处理。Although an excessive number of exceptions usually indicates an application issue, these exceptions might be benign and handled correctly by your application.

如何解决问题?How do I fix it?

通知包括诊断信息,以在诊断进程中提供支持:The notifications include diagnostic information to support in the diagnostics process:

  1. 会审。Triage. 通知会显示有多少用户或多少请求受到影响。The notification shows you how many users or how many requests are affected. 这可以帮助你对问题分配优先级。This can help you assign a priority to the problem.
  2. 划分范围。Scope. 该问题是影响所有流量,还是只影响某些操作?Is the problem affecting all traffic, or just some operation? 可以从通知中获取此信息。This information can be obtained from the notification.
  3. 诊断。Diagnose. 检测包括从中引发异常的方法以及异常类型的相关信息。The detection contains information about the method from which the exception was thrown, as well as the exception type. 还可以使用链接到支持信息的相关项和报告,帮助进一步诊断问题。You can also use the related items and reports linking to supporting information, to help you further diagnose the issue.
