.NET 8–Http Logging

In .NET 7 and before the default request logging in ASP.NET Core is quite noisy, with multiple events emitted per request. That is one of the reasons why I use the Serilog.AspNetCore package.

By adding the following line to my ASP.NET Core application I can reduce the number of events to 1 per request.

The result looks like this in Seq:

	var app = builder.Build();
	app.UseSerilogRequestLogging(); // <-- Add this line

Starting from .NET 8 the HTTP logging middleware has several new capabilities and we no longer need Serilog to achieve the same result.

By configuring the following 2 options, we could achieve this:

• HttpLoggingFields.Duration: When enabled, this emits a new log at the end of the request/response measuring the total time in milliseconds taken for processing. This has been added to the HttpLoggingFields.All set.
• HttpLoggingOptions.CombineLogs: When enabled, the middleware will consolidate all of its enabled logs for a request/response into one log at the end. This includes the request, request body, response, response body, and duration.

Here is a code snippet:

	using Microsoft.AspNetCore.HttpLogging;
	var builder = WebApplication.CreateBuilder(args);
	builder.Services.AddHttpLogging(logging =>
	{
	logging.LoggingFields = HttpLoggingFields.All //Includes HttpLoggingFields.Duration
	logging.CombineLogs = true;
	});

Nice!
