天蓝色。应用洞察。 A日志中莫名其妙的错误信息

Question

我在 Azure 门户中设置了 AppllicationInsights 资源。有 2 个服务写入其中：windows 本地服务和本地服务结构集群上的服务结构服务运行。我在两个服务中都使用 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，但有些消息来源我不明白。这是奇怪消息的示例：

AI: Error collecting 6 of the configured performance counters. Please check the configuration. Counter \ASP.NET Applications(??APP_W3SVC_PROC??)\Requests/Sec: Failed to perform the first read for performance counter. Please make sure it exists. Category: ASP.NET Applications, counter: Requests/Sec, instance SFAIUsingSrv.exe

Counter \ASP.NET Applications(??APP_W3SVC_PROC??)\Requests/Sec: Failed to perform the first read for performance counter. Please make sure it exists. Category: ASP.NET Applications, counter: Requests/Sec, instance SFAIUsingSrv.exe

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

Could anybody help me understand why I am getting those messages?

编辑： 一直在生成这些消息的是我的服务（windows 服务和服务结构服务）。这两项服务都已运行在我的开发箱中。因此，当没有任何网络应用程序被使用时，看到这些与网络应用程序相关的消息是非常混乱的。但是后来我注释掉了 ApplicationInsights.config 文件中的 PerformanceCounterCollector 部分不再生成消息，如果我能找到一种方法以更友好的方式处理这些消息，我会更新我的问题。

编辑2： 这些消息仅在服务启动时显示。

EDIT3: 以下是为服务结构服务安装的所有块包：

Answer 1

如果它是一个 Azure Web 应用程序，只有一部分性能计数器会被 Azure 公开，它们有些记录在此处：

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，则需要确保任何用户运行 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，它包含在 WindowsServer 包中，您可以在 github source for the perf counter collector

此处查看

如果您根本不使用性能收集器的东西，只是希望它全部消失，您可以删除整个

<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。
