在哪里可以找到用于配置Microsoft扩展日志记录的日志记录设置的文档？

Question

Everywhere you can find example on with the default settings

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Debug",
      "System": "Information",
      "Microsoft": "Information"
    }
  }
}

I'd like to know if there is more than that, for exmple if i can customize the format of the message like in NLOG layout attribute.

<target name="logfile" xsi:type="File" fileName="file.txt" layout="${date:format=yyyyMMddHHmmss} ${message}" />

The following answer might not be entirely accurate, since I'm not too familiar with ASP.NET Core Logging. The following is based on some research and looking at source code and examples.

A quick look at the source code of the Microsoft.Extensions.Logging NuGet package (whose source code can be found on GitHub ) reveals that the settings you're showing might be specific to the ConsoleLogger , which doesn't recognize any other settings. See for yourself by looking at the source files here , especially the file ConfigurationConsoleLoggerSettings.cs where you'll find which configuration sections are accessed.

Different loggers might take completely different approaches to read their configuration. For example, NLog can be configured with an XML file. If you want to use NLog, you need to register the appropriate log provider with ASP.NET Core. You want the NLog provider . There's an example project on that project page that demonstrates its basic use:

// add the NuGet package `NLog.Web.AspNetCore` as a project dependency,
// which makes these namespaces available: 
using NLog.Extensions.Logging;
using NLog.Web;

// your ASP.NET Core startup / configuration class:
partial class Startup
{
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        …
        loggerFactory.AddNLog();
        app.AddNLogWeb();
        …
    }
}

Then configure NLog through the NLog.config XML file .
