Support for Application Insights in the Azure Government Cloud [v3.x]

[jcbrooks92]

AI with the government cloud requires a change to point to the government AI endpoint:

"ApplicationInsights": { "InstrumentationKey": "instrumentationkey", "TelemetryChannel": { "EndpointAddress": "https://dc.applicationinsights.us/v2/track" } }
https://docs.microsoft.com/en-us/azure/azure-government/documentation-government-services-monitoringandmanagement#application-insights

We tried the settings below but because the config doesn't allow changes to the TelemetryChannel+ the EndpointAddress this does not work.

https://github.com/Azure/azure-webjobs-sdk/blob/dev/src/Microsoft.Azure.WebJobs.Logging.ApplicationInsights/ApplicationInsightsLoggerOptions.cs

{
  "version": "2.0",
   "logging": {
        "applicationInsights": {
            "TelemetryChannel": {
      "EndpointAddress": "https://dc.applicationinsights.us/v2/track"
    }

        }
    }
}

Copying my comment from issue #2265 here:

In order to use a government cloud you need to adjust the ServerTelemetryChannel's EndpointAddress. You should be able to do this via DI today with something like:

builder.Services.AddSingleton<ITelemetryChannel>(_ => new ServerTelemetryChannel { EndpointAddress = "https://dc.applicationinsights.us/v2/track" });

... but it'd be nice to have it exposed as an easy setting that we auto-apply for you, especially in Functions.

This is the sample I used and I can now see data. Still working on getting the log stream working correctly.

using System;
using Microsoft.ApplicationInsights.Channel;
using Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel;
using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection;


[assembly: FunctionsStartup(typeof(FunctionV2DotNet.Startup))]

 namespace FunctionV2DotNet

{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            builder.Services.AddSingleton<ITelemetryChannel>(_ => new ServerTelemetryChannel { EndpointAddress = "https://dc.applicationinsights.us/v2/track" });
        }
    }
}

Updated startup.cs

This should allow log streaming and the other functionality

using System;
using Microsoft.ApplicationInsights.Channel;
using Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel;
using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.QuickPulse;
using Microsoft.ApplicationInsights.Extensibility.Implementation.ApplicationId;
using Microsoft.ApplicationInsights.Extensibility;
using System.Collections.Generic;
using Microsoft.ApplicationInsights.AspNetCore;
using Microsoft.Extensions.Options;
using System.Linq;

[assembly: FunctionsStartup(typeof(FunctionV2DotNet.Startup))]

 namespace FunctionV2DotNet

{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            builder.Services.AddOptions<TelemetryConfiguration>()
     .Configure<IEnumerable<ITelemetryModuleConfigurator>, IEnumerable<ITelemetryModule>>((telemetryConfig, configurators, modules) =>
     {
         // Run through the registered configurators
         foreach (var configurator in configurators)
         {
             ITelemetryModule telemetryModule = modules.FirstOrDefault((module) => module.GetType() == configurator.TelemetryModuleType);
             if (telemetryModule != null)
             {
                 configurator.Configure(telemetryModule);
             }
         }
     });

            builder.Services.ConfigureTelemetryModule<QuickPulseTelemetryModule>((module, o) => module.QuickPulseServiceEndpoint = "https://quickpulse.applicationinsights.us/QuickPulseService.svc");

            builder.Services.AddSingleton<IApplicationIdProvider>(_ => new ApplicationInsightsApplicationIdProvider() { ProfileQueryEndpoint = "https://dc.applicationinsights.us/api/profiles/{0}/appId" });
            builder.Services.AddSingleton<ITelemetryChannel>(s =>
            {
                // HACK: Need to force the options factory to run somewhere so it'll run through our Configurators.
                var ignore = s.GetService<IOptions<TelemetryConfiguration>>().Value;

                return new ServerTelemetryChannel { EndpointAddress = "https://dc.applicationinsights.us/v2/track" };
            });


        }
    }
}

Unfortunately it works only for AF V2 while we are running on V1..

How would I set the 3 URLs using Azure Functions V1. The example above is using V2. Is it possible in V1?

Dependency Injection is a good solution for DotNet apps - I'd love to see support for other languages, having just encountered this issue with a NodeJs Function App. Ideally App Insights would be made aware of the environment-specific endpoints without user action.

@fabiocav -- we need to get this on the schedule soon. We should expose EndpointAddress/ProfileQueryEndpoint/QuickPulseServiceEndpoint properties that we'll update the right pieces internally.

[fabiocav]

Any idea on the size of this task?

@ahmedelnably for thoughts on priority.

[brettsam]

The engineering work would be pretty small. We need to expose the 3 properties I mention above and funnel them down to, basically, the code above, but in the TelemetryConfiguration initialization code. I've never actually deployed anything to a gov cloud before, though, so we may need some help figuring out how to set that up and validate.

@brettsam let me know if you need help testing this. I'd be happy to help!
