检测到失败请求率异常上升（智能检测） [英] Abnormal rise in failed request rate was detected (Smart Detection)

问题描述

Hello Team， 

我收到了来自"portal.azure.com"的电子邮件。我的网络应用程序中有142％的请求失败。

但是门户网站没有向我显示所提到的失败请求的依赖关系。

 

解决方案

Hello  Vikrantkale ，

警告表示异常上升检测到失败的请求率。您的应用或其环境可能存在问题。

•   " 查看分析通知电子邮件中的此问题"  按钮通常会将您带到Azure门户中的智能检测应用洞察刀片，它会为您提供详细的
  信息引发警报的问题。
• 为了进一步调查，每个部分中的链接将直接带您到
  
  搜索  page 过滤到相关请求，例外，依赖或跟踪。
• 或者您可以打开Azure门户，导航到应用程序的Application Insights资源，然后打开"失败"刀片，并打开
  
  诊断失败从那里挖掘依赖关系和其他可用数据。

请检查上述任何选项是否有助于您找到所需的遥测数据。我还建议你看一下我们详细的文章，内容涉及
的各个方面
智能检测  for failure anomalies with alerting options。

其他信息：

如果您希望在电子邮件中收到更多诊断信息，请选择
"获取更详细的诊断信息" 而
配置警报。通过这种方式，您有时可以仅通过电子邮件中的数据来诊断问题。



即便如此，更详细的警报存在轻微风险可能包含敏感信息，因为它包含异常和跟踪消息。但是，只有当您的代码允许敏感信息进入这些消息时才会发生这种情况。

如果您仍然看到问题，请详细说明您目前在Portal中看到的数据以及相关的屏幕截图和信息，以便我们为您提供进一步的帮助。

希望这会有所帮助！

Hello Team, 

I got an email from "portal.azure.com" of 142% failed request on my web app.

but the portal is not showing me the dependency of mentioned failed request.

 

解决方案

Hello Vikrantkale,

An alert indicates that an abnormal rise in the failed request rate was detected. It's likely that there is some problem with your app or its environment.

• The "See the analysis of this issue" button in the Notification email usually takes you to the Smart Detection blade of Application Insights in the Azure Portal, which gives you detailed information about the issue that raised the alert.
• To investigate further, the links in each section will take you straight to a Search page filtered to the relevant requests, exception, dependency or traces.
• Or you can open the Azure portal, navigate to the Application Insights resource for your app, and open the Failures blade, and diagnose Failures from there digging through Dependencies and other available Data.

Please check if any of the above options help you in finding you the telemetry you need. I would also suggest you take a look at our detailed article covering various aspects of Smart Detection for Failure anomalies with alerting options.

Additional Info:

If you wish to receive more diagnostic information in the email itself, select "Get more detailed diagnostics" while configuring alerts. This way, you'll sometimes be able to diagnose the problem just from the data in the email.

That being said, there's a slight risk that the more detailed alert could contain sensitive information, because it includes exception and trace messages. However, this would only happen if your code could allow sensitive information into those messages.

If you still see issues however, please elaborate on what data you currently see in the Portal with relevant screenshots and information so we can assist you further.

Hope this helps!
