Azure application insights 应用程序洞察：一些指标未通过，不确定如何响应错误消息

我不熟悉应用程序洞察

此票据中的详细信息与特定API有关，该API使用C#编写，带有.NET Framework（非核心），在Windows Server 2012 R2数据中心虚拟机上的IIS中运行

我们为这个API提供了很多ApplicationInsights指标，包括一些我们自己编写的非常有用的自定义遥测

但是一些关键的事情，比如每秒的请求数和每秒失败的请求数都没有通过

我做了一些挖掘，在Application Insights日志中找到了一些与特定API相关的跟踪信息，但我不确定如何处理这些信息

这里有一个例子：

AI:收集3个已配置的性能计数器时出错。请检查配置

计数器\ASP.NET应用程序（？APP\U W3SVC\U PROC？？？）请求/秒：无法执行性能计数器的第一次读取。请确保它存在。类别：ASP.NET应用程序，计数器：请求/秒，实例\u LM\u W3SVC\u 4\u根

计数器\ASP.NET应用程序（？APP\U W3SVC\U PROC？？？）请求执行时间：未能执行性能计数器的第一次读取。请确保它存在。类别：ASP.NET应用程序，计数器：请求执行时间，实例\u LM\u W3SVC\u 4\u根

计数器\ASP.NET应用程序（？APP\U W3SVC\U PROC？？？）应用程序队列中的请求：未能执行性能计数器的第一次读取。请确保它存在。类别：ASP.NET应用程序，计数器：应用程序队列中的请求，实例_LM_W3SVC_4_根

另一个例子：

AI:ApplicationInsights配置文件加载失败。未找到类型“Microsoft.ApplicationInsights.StatusMonitor.SdkSourceTelemetryInitializer，Microsoft.AI.StatusMonitor”。已跳过类型加载。监测工作将继续进行

以下是相关网站的ApplicationInsights.config文件：

因为我是新手，我真的不知道从哪里开始。我试着用谷歌搜索错误信息，但我没有找到多少对我目前的情况有用的信息

非常感谢任何指向正确方向的指针。

您使用的SDK版本是什么？您是否将application insights SDK添加到应用程序本身，或者使用状态监视器在运行时为应用程序添加工具

关于PerfCounters的错误表示SDK在尝试收集提到的计数器时遇到错误。您是否看到其他计数器，如进程CPU、内存等？如果是，则问题仅与Asp.Net相关的计数器有关。您是否可以使用perfmon之类的工具来验证机器中是否存在这些计数器

您可以从Ai.Config中删除以下行，以消除有关StatusMonitor initialier的错误-我不确定它的作用，但它无法解释您丢失某些数据的原因

请分享更多信息-sdk版本、web.config、如何登录等，我会尽力提供更多帮助
