【问题描述】：

我有一个现有的 Service Fabric 群集，其中包含我从 Azure 示例中获得的 application，现在，我正在尝试启用 Application Insights 来监视群集，在创建 Application Insight 之后，我复制了连接字符串并前往 VM 规模集，然后我使用我拥有的连接字符串安装了 Application Insights 扩展，但在安装过程完成后，我收到此错误消息

VM has reported a failure when processing extension 'ApplicationMonitoringWindows'. Error message: "Failed to enable application monitoring for IIS: System.IO.FileNotFoundException: Cannot find applicationHost.config at C:\windows\System32\inetsrv\config\applicationHost.config File name: 'C:\windows\System32\inetsrv\config\applicationHost.config' at Microsoft.ApplicationInsights.Redfield.Configurator.RuntimeConfigurators.IISConfigurator.UpdateApplicationHostConfig(IAppInsightsConfiguratorLogger logger, Boolean enable, Boolean skipMissingApplicationHostConfig, ISystem system) at Microsoft.ApplicationInsights.Redfield.Configurator.RuntimeConfigurators.IISConfigurator.Enable(IRuntimePaths runtimePaths, IAppInsightsConfiguratorLogger logger, Boolean writeToApplicationHostConfig, Boolean skipMissingApplicationHostConfig, ISystem system) at Microsoft.ApplicationInsights.Redfield.Configurator.RedfieldConfigurator.Enable(IRuntimePaths runtimePaths, IAppInsightsConfiguratorLogger logger, RedfieldConfiguration redfieldConfiguration, Boolean enableInstrumentationEngine, Boolean writeToApplicationHostConfig, Boolean skipMissingApplicationHostConfig) at Microsoft.ApplicationInsights.VmExtensionHandler.VmExtensionHandler.Enable(HandlerEnvironment handlerEnvironment, String configSequenceNumber)" More information on troubleshooting is available at https://aka.ms/vmextensionwindowstroubleshoot

我关注this 文档并在同一个 VM 规模集中安装了一个自定义 powershell 脚本扩展，下面是 ps 脚本

@
  "redfieldConfiguration"= @
    "instrumentationKeyMap"= @
      "filters"= @(
        @
          "appFilter"= ".*";
          "machineFilter"= ".*";
          "virtualPathFilter": ".*",
          "instrumentationSettings" : 
            "connectionString": "XXXXXXXXXXXXXXXXXXXXXX"
          
        
      )
    
  
;
$privateCfgHashtable = @;

$vmss = Get-AzVmss -ResourceGroupName "XXXXX" -VMScaleSetName "XXXXX"

Add-AzVmssExtension -VirtualMachineScaleSet $vmss -Name "ApplicationMonitoring" -Publisher "Microsoft.Azure.Diagnostics" -Type "ApplicationMonitoringWindows" -TypeHandlerVersion "2.8" -Setting $publicCfgHashtable -ProtectedSetting $privateCfgHashtable

Update-AzVmss -ResourceGroupName $vmss.ResourceGroupName -Name $vmss.Name -VirtualMachineScaleSet $vmss

有没有我想念的地方？谢谢！

我建议您关注monitoring your SF cluster 官方文档中的this tutorial。

由于您已经运行 .Net 应用并设置了您的应用洞察资源，您可以instrument 它来抽取必要的遥测数据。

Application Insights 有两个特定于 Service Fabric 的 NuGet，可根据场景使用。一种用于 Service Fabric 的本机服务，另一种用于容器和来宾可执行文件。若要详细了解 Application Insights SDK 和特定于 Service Fabric 的 NuGet 包，请参阅Microsoft Application Insights for Service Fabric。

然后，您可以在 Azure 门户上的 Application Insights 资源中查看应用的遥测数据。如果需要，您还可以将自定义检测添加到您的应用程序以改进诊断。
