In Blazor how do I get Logger talking to ApplicationInsights

Question

In Blazor how do I get Logger talking to ApplicationInsights

David Thielen 3,211

I am finding explinations like this (and others) reference methods that don't exist.

There is no builder.Logging.AddApplicationInsightsTelemetry() nor is there a builder.Services.AddBlazorApplicationInsights()

What I did try was:

var builder = WebApplication.CreateBuilder(args);
builder.Logging.AddApplicationInsights();

and in appsettings.json I have:

"ApplicationInsights": {
    "ConnectionString": "InstrumentationKey=***guid***;IngestionEndpoint=https://eastus-8.in.applicationinsights.azure.com/;LiveEndpoint=https://eastus.livediagnostics.monitor.azure.com/"
  },

When I run nothing is written to Application Insights. And my output has the following:

Application Insights Telemetry (unconfigured): {"name":"AppTraces","time":"2023-06-28T22:15:49.4249016Z","tags":{"ai.cloud.roleInstance":"Jasmine","ai.internal.sdkVersion":"il:2.22.0-533"},"data":{"baseType":"MessageData","baseData":{"ver":2,"message":"Now listening on: https://localhost:7229","severityLevel":"Information","properties":{"CategoryName":"Microsoft.Hosting.Lifetime","EventName":"ListeningOnAddress","OriginalFormat":"Now listening on: {address}","address":"https://localhost:7229","EventId":"14"}}}}

Any ideas how I can get this working?

Hi,@David Thielen,

There is no builder.Logging.AddApplicationInsightsTelemetry() nor is there a builder.Services.AddBlazorApplicationInsights()

What's the .net version of your project?Have you included the following packages ?

<ItemGroup> <PackageReference Include="BlazorApplicationInsights" Version="2.2.0" /> <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.21.0" /> </ItemGroup>

@Anonymous I agree there's not. It seems every link I find on this topic lists different methods to call, none of which exist. This class is another where it shows methods that don't exist, at least not in Blazor. And yet the code compiles & runs in the videos.

I have Microsoft.ApplicationInsights.AspNetCore installed. I do not have BlazorApplicationInsights installed. What does that provide and is it documented anywhere. I'm a little concerned by it as it's not from Microsoft but 620K downloads is a good vote of confidence.

And by any chance can you point me to a web page that gives full instructions on connecting my logging & monitoring to ApplicationInsights?

thanks - dave

Hi,@David Thielen,

BlazorApplicationInsights is a third-part tool.

Here's the documents related,hopes help:

https://learn.microsoft.com/en-us/aspnet/core/blazor/fundamentals/handle-errors?view=aspnetcore-7.0#log-errors-with-a-persistent-provider

@Anonymous Thanks for the links. I went through both again and added the following:

builder.Logging.AddApplicationInsights(); builder.Services.AddApplicationInsightsTelemetry();

This works! So all good now.

thanks - dave

Answer 1

Here's what I did to get it working:

2. NuGet - Microsoft.ApplicationInsights.AspNetCore
3. Azure | Create Resource | Application Insights | Create
	1. [Go to resource] | copy Connection String (upper right)
4. Program.cs
	1. builder.Logging.ClearProviders(); // if want only Application Insights
	2. builder.Logging.AddApplicationInsights();
	3. builder.Services.AddApplicationInsightsTelemetry();
5. appsettings.json
	1. "ApplicationInsights": {"ConnectionString": "the connection string "},
	2. Under "Logging": {
		1. "ApplicationInsights": {"LogLevel" ... },
6. To view
	1. Logs | traces (in query editor)
		1. Also look at exceptions
