Log Request and Response Details of your Actions in ASP.NET Core.

• Execution date time (TimeStamp)
• Execution duration (Elapsed)
• Action Arguments (like your ViewModels)
• ModelState (IsValid and Errors)
• Request Path (Host and QueryString and RouteValues)
• Request Method
• Request Cookies
• Request Headers
• User.Identity (UserName and IsAuthenticated and Claims)
• Response Cookies
• Response Headers
• Response StatusCode
• IpAddress
• UrlReferrer
• Exception if thrown

You can add your desired details like UserAgent info (such as browser, os, ... details) in LogRequestAttribute.OnActionExecuting

Just put [LogRequest] attribute on your actions or register it globally

public class HomeController : Controller
    {
        public HomeController()
        {
        }

        [LogRequest]
        public IActionResult Index(MyViewModel myViewModel)
        {
            return View();
        }

        [LogRequest]
        public IActionResult Privacy()
        {
            throw new Exception("test");
            return View();
        }
    }

Check out Program.cs and Startup.cs to see how to Configuration.

This uses Serilog and Serilog.AspNetCore for logging and MSSqlServer sink but you can use any other Sinks.
