【问题标题】:Error Installing Application Insights on a Service Fabric Cluster在 Service Fabric 群集上安装 Application Insights 时出错
【发布时间】:2021-03-14 18:53:11
【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!

    【解决方案1】:

    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。
