Azure Logs Monitor: console logs level is not correct

Question

We use basic console logging in JSON single-line format. appsettings.json looks like the following.

"Logging": {
  "LogLevel": {
    "Default": "Information",
    "Microsoft": "Warning",
    "Microsoft.Hosting.Lifetime": "Information"
  },
  "Console": {
    "FormatterName": "json",
    "FormatterOptions": {
      "SingleLine": true,
      "IncludeScopes": true,
      "UseUtcTimestamp": true
    }
  }
}   

Configuration: Microsoft.Extensions.Logging 7.0.0 and we do not have a custom implementation nor third-party solution like NLog.

The issue is that in Azure Logs Monitor, the Level column has the Informational type every time. How is it recognized? Should we change the format of the logged message to be correctly recognized?

@David

The level comes from your method used by your ILogger<T> implementation, i.e., _logger.LogInformation or _logger.Log(LogLevel.Information,...), see Logging in .NET Core and ASP.NET Core | Microsoft Learn for more information.

I'm making assumptions based off what you've provided, but it looks as if you're logging event or object as Information in your code, so I would search for those categories that are shown in ResultDescription and see what sort of (bubble up) logging is taking place.
