Managing Logging Levels Across Environments in ASP.NET Core

It’s best practice to tailor logging levels per environment (Development, Staging, Production) by using environment-specific configuration files like appsettings.Development.json or appsettings.Production.json.

Example for Development (verbose logging):

{
  "Logging": {
    "LogLevel": {
      "Default": "Debug",
      "Microsoft": "Information",
      "System": "Warning",
      "YourAppNamespace": "Trace"
    }
  }
}

Example for Production (concise logging):

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

By adjusting log levels per environment, you can capture detailed diagnostics during development while reducing noise and performance impact in production.
