Azure上.ApplicationInsights.AI日志中无法解释的错误信息

Question

我在Azure门户中设置了AppllicationInsights资源.有两种服务写入:本地Windows服务和本地服务结构集群上运行的服务结构服务.我在两个服务中使用TelemetryClient对象将数据发送到Azure ApplicationInsights资源.看起来我收到了我想要的所有消息,但是有些消息来源我不明白.以下是奇怪消息的示例:

AI:收集6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_W3SVC_PROC ??)\ Requests/Sec: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SFAIUsingSrv.exe
计数器.NET CLR异常(?? APP_CLR_PROC ??)Exceps Thrown/sec的数量:无法执行性能计数器的第一次读取.请确保它存在.类别:.NET CLR异常,计数器:Exceps Thrown/sec的数量,实例

.Counter\ASP.NET应用程序(?? APP_W3SVC_PROC ??)\应用程序队列中的请求: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:请求在应用程序队列中,实例SFAIUsingSrv.exe

计数器\ ASP.NET应用程序(?? APP_W3SVC_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:Requests/Sec,实例SFAIUsingSrv.exe

这是我的服务结构服务的ApplicationInsights.config:

有人能帮助我理解为什么我收到这些消息吗？

编辑: 这是我的服务(Windows服务和服务结构服务)已经产生这些消息.这两项服务都在我的开发盒上运行.因此,当没有使用任何Web应用程序时,看到与Web应用程序相关的消息非常令人困惑.但后来我注释掉ApplicationInsights.config中的PerformanceCounterCollector部分,不再生成文件消息,如果我能找到一种以更友好的方式处理这些消息的方法,我会更新我的问题.

EDIT2: 仅在服务启动时才显示这些消息.

EDIT3:以下是为服务结构服务安装的所有块包:

Answer 1

如果它是Azure Web应用程序,Azure只公开了一部分perfcounter,它们在这里有一些记录:

https://github.com/Microsoft/ApplicationInsights-dotnet-server/blob/develop/Src/PerformanceCollector/Shared/Implementation/WebAppPerformanceCollector/CounterFactory.cs

如果您正在控制服务器,则需要确保运行的任何用户IIS网站/应用程序池都是Performance Monitor Users组的成员,以便它可以读取性能计数器.

这些消息来自PerfCounterCollector包的默认配置,该配置包含在WindowsServer包中,您可以在github源中看到这些包用于perf计数器收集器

如果你根本没有使用性能收集器的东西而只是希望它们全部消失,你可以删除整个

<Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.PerformanceCollectorModule, Microsoft.AI.PerfCounterCollector">
...stuff about perf counters here...
</Add>

部分和Application Insights将停止尝试完全收集性能计数器.
