NLog, custom LogLevels

In the config file config.json I have this entry

 "Logging": {
    "LogLevel": {
        "Default": "Trace",
        "Microsoft": "Warning",
        "Microsoft.Hosting.Lifetime": "Information",
        "MyEntry": "Critical"
    }
  }

I'm lacking the terminology to do a proper search here.

I've added an extra entry, "MyEntry". What is that? Is it a category? What would I need to do to get it to do something?

What I'm actually trying to do is just make a reference sandbox project so that I can play with the various settings of nlog

Sorted now thanks to the help in the comments

Here's 2 examples, one using a class name, and one using a random name.

The log file

    "LogLevel": {
        "Default": "Critical",
        "Microsoft": "Critical",
        "Microsoft.Hosting.Lifetime": "Critical",
        "NLogUsing.Controllers.TempController": "Critical",
        "SomeRandomNameLogger": "Information"
    }
  },

And some code that uses it

namespace NLogUsing.Controllers
{
   [Route("/Temp")]
    public class TempController : Controller
    {
        private readonly ILogger<TempController> classLogger;
        private readonly Microsoft.Extensions.Logging.ILogger namedLogger = null;

        public TempController(ILogger<TempController> logger, ILoggerFactory logFactory)
        {
            classLogger = logger;
            namedLogger = logFactory.CreateLogger("SomeRandomNameLogger");
        }

        [AllowAnonymous]
        [HttpGet("Bob")]
        public async Task<string> Bob()
        {
            classLogger.LogDebug(1, "ClassName Debug");
            classLogger.LogInformation(1, "ClassName Info");
            classLogger.LogTrace(1, "ClassName trace");
            classLogger.LogWarning(1, "ClassName warning");
            classLogger.LogCritical(1, "ClassName critical");
            classLogger.LogError(1, "ClassName error");

            namedLogger.LogDebug(1, "Named Debug");
            namedLogger.LogInformation(1, "Named Info");
            namedLogger.LogTrace(1, "Named trace");
            namedLogger.LogWarning(1, "Named warning");
            namedLogger.LogCritical(1, "Named critical");
            namedLogger.LogError(1, "Named error");


            return await Task.FromResult<string>("Bob");
        }
