this article 以及 here .

在安装了nugget包并添加了一行代码之后,我在调试和发布模式下本地运行了云服务,并且能够看到AI信息被报告给Application Insights资源。因此,我将其打包并将新配置上传到我的云服务。

this article 这一错误基本上告诉了我为什么它会继续回收,但没有任何关于如何处理它的线索。

生产-WebReportDownloader_IN_0:BusyRole

通常我可以从搜索异常和/或详细信息中得到足够的提示,但这次我找不到任何与我的问题类似的东西。我所能猜到的是,我的配置出现了一些小但关键的错误,但我还无法根据上面链接的说明确定我偏离了轨道的地方。

我的服务配置。云文件。。。

    <?xml version="1.0" encoding="utf-8"?>

还有我的“OnStart()”方法,我在其中实际设置InstrumentationKey。。。

public override bool OnStart()
        {
            // Set the maximum number of concurrent connections
            ServicePointManager.DefaultConnectionLimit = 12;
            TelemetryConfiguration.Active.InstrumentationKey = RoleEnvironment.GetConfigurationSettingValue("APPINSIGHTS_INSTRUMENTATIONKEY");

            // For information on handling configuration changes
            // see the MSDN topic at https://go.microsoft.com/fwlink/?LinkId=166357.

            bool result = base.OnStart();

            Trace.TraceInformation("WebReportDownloader has been started");

            return result;
        }

如果有任何见解,我将不胜感激(哈!)或者任何人都可以提供的指导。。。

通过进一步的实验,我确定每当我试图直接调用Application Insights程序集时(例如在创建遥测客户端或直接设置ApplicationInsights资源键时),或者在由于跟踪而调用ApplicationInsights TraceListener时,都会调用下面的异常

此外,我目前的目标是。NET 4.6.1(我之前忽略提及的信息)。

在Azure的支持下,我终于能够建立一个屏幕共享会话。这位乐于助人的绅士几乎立即把注意力集中在这个问题上: 服务配置文件(Cloud.cscfg和.Local.cscfg) .

VS17向导生成的默认值将其设置为osFamily=4,如下所示。。。

这一小改动允许web角色在实例化遥测客户端时正确部署。

Microsoft.ApplicationInsights.WindowsServer 2.4.1 刚才添加了您提到的用于设置插装键的代码,如下所示:

WorkerRole。反恐精英

public class WorkerRole : RoleEntryPoint
{
    private readonly CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();
    private readonly ManualResetEvent runCompleteEvent = new ManualResetEvent(false);

    public override void Run()
    {
        Trace.TraceInformation("WorkerRoleB is running");

        try
        {
            this.RunAsync(this.cancellationTokenSource.Token).Wait();
        }
        finally
        {
            this.runCompleteEvent.Set();
        }
    }

    public override bool OnStart()
    {
        // Set the maximum number of concurrent connections
        ServicePointManager.DefaultConnectionLimit = 12;

        TelemetryConfiguration.Active.InstrumentationKey = RoleEnvironment.GetConfigurationSettingValue("APPINSIGHTS_INSTRUMENTATIONKEY");

        // For information on handling configuration changes
        // see the MSDN topic at https://go.microsoft.com/fwlink/?LinkId=166357.

        bool result = base.OnStart();

        Trace.TraceInformation("WorkerRoleB has been started");

        return result;
    }

    public override void OnStop()
    {
        Trace.TraceInformation("WorkerRoleB is stopping");

        this.cancellationTokenSource.Cancel();
        this.runCompleteEvent.WaitOne();

        base.OnStop();

        Trace.TraceInformation("WorkerRoleB has stopped");
    }

    private async Task RunAsync(CancellationToken cancellationToken)
    {
        // TODO: Replace the following with your own logic.
        while (!cancellationToken.IsCancellationRequested)
        {
            Trace.TraceInformation("Working");
            await Task.Delay(1000);
        }
    }
}

部署到Azure云服务后,它可以按预期工作,我可以从AI检索诊断数据,如下所示:

像 Install the SDK in each project 声明您需要设置 ApplicationInsights.config

quick start 并在运行时检测应用程序以缩小此问题。此外,如果我错过了一些东西,或者你做了一些其他特殊代码,你可以更新你的问题,让我们解决这个问题。
