我是Application Insights的新手。
此票证中的详细信息与在Windows Server 2012 R2数据中心虚拟机上的IIS中运行的,使用.NET Framework(不是Core)用C#编写的特定API有关。
我们有很多针对此API的Application Insights度量标准,包括我们自己编写的一些自定义遥测功能,这些功能非常有用。
但是每秒的请求数和每秒失败的请求数之类的关键信息并没有通过。
我已经进行了一些挖掘,并且在Application Insights日志中找到了该特定API的一些跟踪信息,这些跟踪信息看起来可能是相关的,但是我不确定该如何处理。
这里是一个例子:
AI:收集3个已配置的性能计数器时出错。请检查配置。
Counter \ ASP.NET Applications(?? APP_W3SVC_PROC ??)\ Requests / Sec:无法执行对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_LM_W3SVC_4_ROOT
计数器\ ASP.NET应用程序(?? APP_W3SVC_PROC ??)\请求执行时间:无法为性能计数器执行第一次读取。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_LM_W3SVC_4_ROOT
Counter \ ASP.NET Applications(?? APP_W3SVC_PROC ??)\ Application Queue中的请求:无法为性能计数器执行第一次读取。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_ROOT
另一个例子:
AI:ApplicationInsights配置文件加载失败。找不到类型'Microsoft.ApplicationInsights.StatusMonitor.SdkSourceTelemetryInitializer,Microsoft.AI.StatusMonitor'。类型加载被跳过。监视将继续。

因为我是新手,所以我不确定从哪里开始。我曾尝试使用Google搜索错误消息,但并没有提出对当前情况有用的建议。
任何朝着正确方向的指针都会受到赞赏。
答案 0 :(得分:0)
您使用的SDK是什么版本?您是否向应用程序本身添加了应用程序见解SDK,还是使用状态监视器在运行时对应用程序进行了检测?
关于PerfCounters的错误表明SDK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,例如进程CPU,内存等?如果是,则问题仅在于与Asp.Net相关的计数器。您可以使用诸如perfmon之类的工具来验证这些计数器是否确实存在于计算机中吗?
您可以从Ai.Config中删除以下行,以消除有关StatusMonitor初始值的错误-我不确定它的作用,但无法解释为什么您缺少一些数据。
<Add Type="Microsoft.ApplicationInsights.StatusMonitor.SdkSourceTelemetryInitializer, Microsoft.AI.StatusMonitor" />
要真正解释为什么您看不到“请求”相关指标,需要查看应用程序的web.config。您可能遇到了以下问题: https://github.com/Microsoft/ApplicationInsights-dotnet-server/issues/569
请分享更多信息-sdk版本,web.config,如何启用等,我会尽力帮助您。
