Would be possible to use LogLevel structure ?

[JiriZidek]

It looks like appsettings.json parameter
"MinLevel": "Warning", // min level for the file logger
replaces normal

    "LogLevel": {
      "Default": "Information",
      "System": "Warning",
      "Microsoft": "Warning"
    }

Am I missing something ? Is tehre any plan to use the microsoftish way of configuring levels ?
Thanks for clarification. Jiri

Message filtering rules are applied inside logging infrastructure (Microsoft.Extensions.Logging) and works for all logging providers in a same way.

However, you can specify min log level exactly for FileLoggingProvider (say, write to a file only "Warning" and "Error" entries).

So using "MinLevel": "Warning" is in fact very same like setting:
{
"File": {
"LogLevel": {
"Default": "Warning"
},
.....
}
OK, clear now.
