Application Insights Live Metrics with ASP.Net MVC and Web Api

Question

we want to monitor one of our application with Azure Application Insights. It is an ASP.Net 4 MVC application with Web Api 2. I've created a new Application Insights resource in Azure and I've installed the following NuGet packages into the project:

<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" />

The ApplicationInsights.config looks like the following:

    <?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.

But Application Insights does for exmample not show the live metrics or the server requests.

I've tried the access to App Insights, via a test program, which is woring, all data (Live metrics, requests, etc.) were shown correctly: using Microsoft.ApplicationInsights; using System;

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();
        }
    }
}

How do I have to configure App Insights in an MVC/Web Api project so that it works correctly.

Thanks in advance.

Update with screenshots form Visual Studio (2017) and Azure Portal: VS:

Azure Portal (in german):

Answer 1

After ignoring this task for a long time I've finally found the answer. The service is hosted behind a company proxy and to enable it send the data to azure you've to add the proxy to your web.config:

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

You have to adopt the settings dependent of your proxy configuration.

Answer 2

I add Application Insights to my existing MVC project with the following steps, I can get live metrics stream and server requests metrics, please refer to it.

• Right-click web app project in Solution Explorer, and choose Add > Application Insights Telemetry... , and then register app with Application Insights and configure Application Insights. (Which will help us install Application Insights related packages and configure projects.)

• Open web pages to generate some telemetry

• On Azure portal, I can see the number of online servers and Live metrics stream.

  

• Add chart to show server requests

  

  

Besides, you could also refer to this article that shows how to configure your ASP.NET web app to send telemetry to the Azure Application Insights service.

Answer 3

Your Azure application insights resource is not linked to your web application.

In Azure portal find your Application Insights resource and navigate to Configure->Properties.

There you will find "INSTRUMENTATION KEY".

Copy that key to your applicationInsights.config section:

<InstrumentationKey>Our key</InstrumentationKey>
