Using serilog with azure application insights and .Net core

Question

Currently, I am using azure application insights directly for logging as given in this link Use latest version of Application Insight with .net core API and everything is working fine.

But I need to use the serilog for logging now with the help of azure application insight. Even I do some R&D about serilog (https://github.com/serilog/serilog-sinks-applicationinsights). But didn't get any idea. Could you please suggest me that how can we achieve that with the .Net core 3.0

What is the problem? You've linked to the Serilog application insights sink which is exactly what you need to add to your project. I speak from experience when I say it works — pinkfloydx33, May 20 '20 at 08:33

Please follow the steps below:

First, in stall the following packages:

Microsoft.ApplicationInsights.AspNetCore, version 2.14.0

Serilog.AspNetCore, version 3.2.0

Serilog.Sinks.ApplicationInsights, version 3.1.0

Serilog.Settings.Configuration, version 3.1.0

In Program.cs:

public class Program
{     
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            })
           .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                    .ReadFrom.Configuration(hostingContext.Configuration)
                    .WriteTo.ApplicationInsights(new TelemetryConfiguration{ InstrumentationKey = "xxxxxxxxx" },TelemetryConverter.Traces)
             );                
}

In controller.cs:

How do you configure application insights settings like sampling configuration? – frosty Apr 16 '21 at 21:48

Where the instrumentation key comes from? – Lesair Valmont May 28 '21 at 18:35
@LesairValmont, if you have an Application Insights created, then please go to azure portal -> your Application Insights -> Overview page: then you can find Instrumentation Key there. – Ivan Glasenberg May 31 '21 at 00:43
Mine is actually working but... any ideas on why isn't the "live telemetry" actually working? – Gonzo345 Oct 25 '21 at 11:58

I think you forgot to add how appsettings.json looks for serilog – Hazaaa Apr 28 '22 at 08:23

Here is information how to setup app configuration for asp net core, but it for v6.x

https://learn.microsoft.com/en-us/azure/azure-monitor/app/asp-net-core?tabs=netcorenew%2Cnetcore6

appsettings.json (example)

{
"Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "AllowedHosts": "*",
  "ApplicationInsights": {
    "ConnectionString": "Copy connection string from Application Insights Resource Overview"
  }
}
