c# - 使用 ASP.Net MVC 和 Web Api 的 Application Insights 实时指标

Question

我们希望使用 Azure Application Insights 监控我们的一个应用程序。它是一个具有 Web Api 2 的 ASP.Net 4 MVC 应用程序。我在 Azure 中创建了一个新的 Application Insights 资源，并将以下 NuGet 包安装到项目中:

<package id="Microsoft.ApplicationInsights" version="2.3.0" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.Agent.Intercept" version="2.0.7" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.DependencyCollector" version="2.3.0" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.PerfCounterCollector" version="2.3.0" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.TraceListener" version="2.2.0" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.Web" version="2.3.0" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.WindowsServer" version="2.3.0" targetFramework="net462" />
<package id="Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel" version="2.3.0" targetFramework="net462" />

ApplicationInsights.config 如下所示:

    <?xml version="1.0" encoding="utf-8"?>
<ApplicationInsights xmlns="http://schemas.microsoft.com/ApplicationInsights/2013/Settings">
<!-- This key is for Application Insights resource 'PlanningTool.Web' in resource group 'Default-ApplicationInsights-CentralUS' -->
<InstrumentationKey>Our key</InstrumentationKey>
<TelemetryModules>
    <Add Type="Microsoft.ApplicationInsights.DependencyCollector.DependencyTrackingTelemetryModule, Microsoft.AI.DependencyCollector" />
    <Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.PerformanceCollectorModule, Microsoft.AI.PerfCounterCollector">
    <!--
    Use the following syntax here to collect additional performance counters:

    <Counters>
        <Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\Handle Count" ReportAs="Process handle count" />
        ...
    </Counters>

    PerformanceCounter must be either \CategoryName(InstanceName)\CounterName or \CategoryName\CounterName

    NOTE: performance counters configuration will be lost upon NuGet upgrade.

    The following placeholders are supported as InstanceName:
        ??APP_WIN32_PROC?? - instance name of the application process  for Win32 counters.
        ??APP_W3SVC_PROC?? - instance name of the application IIS worker process for IIS/ASP.NET counters.
        ??APP_CLR_PROC?? - instance name of the application CLR process for .NET counters.

</ApplicationInsights>

但是 Application Insights 确实不显示实时指标或服务器请求。

我尝试通过测试程序访问 App Insights，该程序正在运行，所有数据(实时指标、请求等)均正确显示: 使用 Microsoft.ApplicationInsights； 使用系统；

namespace AppInsightsTest
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Application Insights Test");
            var e = new Exception("This is a App Insights test");
            var ai = new TelemetryClient();
            ai.TrackException(e);
            Console.WriteLine("Finished...");
            Console.ReadKey();
        }
    }
}

如何在 MVC/Web Api 项目中配置 App Insights 才能正常工作。

提前致谢。

使用 Visual Studio (2017) 和 Azure 门户的屏幕截图进行更新:对比:

在忽略这个任务很长一段时间后，我终于找到了答案。该服务托管在公司代理后面，要使其能够将数据发送到 azure，您必须将代理添加到您的 web.config:

<configuration>
     <system.net enabled="true" useDefaultCredentials="true">
         <proxy proxyaddress="http://url.to.your.proxy" bypasslocal="true" />
     </system.net>
</configuration>

您必须采用取决于您的代理配置的设置。
