Nlog does not log Trace events in asp.net core 2

[xumix]

NLog.Web.AspNetCore 4.5.0-beta04, asp.net core 2.0.3

The code: https://gist.github.com/xumix/3cfb305dfd0f3cb743f9f25908212e4e
I add in Startup.cs

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddConsole();
            loggerFactory.AddDebug();
            app.UseMiddleware<RequestLoggingMiddleware>();

            LayoutRenderer.Register("basedir", (logEvent) => env.ContentRootPath);
}

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="info"
      internalLogFile="c:\temp\internal-nlog.txt">
  <!-- the targets to write to -->
  <targets>
    <target xsi:type="File" name="request-file" fileName="${basedir}/logs/request-${shortdate}.log"
            layout="${longdate}|${uppercase:${level}}|${logger}|${message}" />
  </targets>

 <rules>
    <logger name="*RequestLoggingMiddleware*" writeTo="request-file" final="true" />
  </rules>
</nlog>

If I change logger.LogInformation(requestLog); to logger.LogTrace(requestLog); then no logging occurs, even if I add minlevel="Trace"

Use configureLogging and

builder.SetMinimumLevel()

PS on mobile now

[snakefoot]

Program.cs should be extended to include ConfigureLogging(l => l.SetMinimumLevel(LogLevel.Trace)) :

using Microsoft.Extensions.Logging;  // Required for calling extension method SetMinimumLevel

public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .ConfigureLogging(l => l.SetMinimumLevel(LogLevel.Trace))
            .UseNLog()
            .Build();

This works with AddNLog (ASP.NET Core 1 style), but not with UseNLog (see ##234) - any idea?

No idea. Just copy pasting random information :). Not developing ASP NET Applications.

Hopefully that doesn't mean WinForms ;)

@304NotModified @snakefoot thanks!

No just backend developer on various data-processing engines.

@xumix Maybe my rant at #234 might be useful. Seems asp.net core 2 will choose appsettings.json LogLevel-config when available.

@snakefoot you sir, are awesome. I would have never guessed that in a million years. Thank you.

Removing config from appsettings.json and setting minimum level worked for me.

Hi guys,

It looks like this is still a problem in .NET Core 3.1.
Any advice, please?

[snakefoot]

Please create new issue instead of waking up old issues with your random problems. Remember to fill out the template with details about how you setup NLog

And indeed, if it still an issue, please open a new github issue, thanks!
