Cant set asp net core console logging below information

Introduction

ASP.NET is a popular language used for building web applications. One common issue that face is the inability to set the ASP.NET Core logging the information level. In this article, we will explore approaches to solve this problem and provide examples to illustrate the solutions.

Solution 1: Using the Logging Configuration

One way to solve this issue is by modifying the logging configuration in the ASP.NET Core application. By , the logging level is set to “Information,” which means that only log messages with a level of “Information” or higher will be displayed in the console. To set the logging level to a lower level, such as “Debug” or “Trace,” you can modify the appsettings.json file.


{
  "Logging": {
    "LogLevel": {
      "Default": "Debug",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  }
}

In the above example, the logging level is set to “Debug” for the default category, “Warning” for the Microsoft category, and “Information” for the Microsoft.Hosting.Lifetime category. This means that log messages with a level of “Debug” or higher will be displayed in the console.

Solution 2: Modifying the Logging Configuration Programmatically

If you prefer to modify the logging configuration programmatically, you can do so in the .cs file of your ASP.NET Core application. In the ConfigureServices method, you can access the ILoggerFactory and modify the logging level for the console .


public void ConfigureServices(IServiceCollection services)
{
    // Other configuration code

    services.AddLogging(builder =>
    {
        builder.AddConsole();
        builder.SetMinimumLevel(LogLevel.Debug);
    });

    // Other configuration code
}

In the above example, the SetMinimumLevel method is used to set the minimum logging level to “Debug” for the console logger. This will ensure that log messages with a level of “Debug” or higher are displayed in the console.

Solution 3: Using a Custom Logger

If the above solutions do not meet your requirements, you can create a custom logger that allows you to set the logging level as per your needs. This can be achieved by implementing the ILogger interface and configuring it in your application.


public class CustomLogger : ILogger
{
    // Implement the ILogger interface methods here
}

public void ConfigureServices(IServiceCollection services)
{
    // Other configuration code

    services.AddLogging(builder =>
    {
        builder.AddConsole();
        builder.AddProvider(new CustomLoggerProvider());
    });

    // Other configuration code
}

In the above example, a custom logger CustomLogger is implemented by implementing the ILogger interface. This logger can be added to the logging configuration using the AddProvider method.

Conclusion

In this article, we explored different solutions to the problem of setting the ASP.NET Core console logging below the information level. We discussed modifying the logging configuration in the appsettings.json file, modifying the logging configuration programmatically in the Startup.cs file, and a custom logger. By implementing these solutions, developers can have more control over the logging level in their ASP.NET Core applications.
