Test4Net.Logging

Introduction

Net core logger. Can incorporate log4net with log4net aspNetCore extension.

Examples

Simple logger

var log = LogProvider._GetLogger<Program>();
log.Info("Info message !!!", 1, 2, 3);
log.Warn("Warn message !!!", 1, 2, 3);
log.Debug("Debug message !!!", 1, 2, 3);
log.Error(new ArgumentException(".......No arguments!!"), "Error message !!!", 1, 2, 3);

Decorating logger with configuration

var log = LogProvider._GetLogger<Program>(builder => builder.Decorate(TestConfiguration.GetSection("Logging")))

where json format is:

{
  "Logging": {
    "LogLevel": { // All providers, LogLevel applies to all the enabled providers.
      "Default": "Error", // Default logging, Error and higher.
      "Microsoft": "Warning" // All Microsoft* categories, Warning and higher.
    },
    "Debug": { // Debug provider.
      "LogLevel": {
        "Default": "Information", // Overrides preceding LogLevel:Default setting.
        "Microsoft.Hosting": "Trace" // Debug:Microsoft.Hosting category.
      }
    },
    "EventSource": { // EventSource provider
      "LogLevel": {
        "Default": "Warning" // All categories of EventSource provider.
      }
    }
  }
}

More about log formatter Creating logger using dependency injection

 // Define loggers
var loggerTypes = new[]
    { typeof(LogAdapter<TargetClassA>), typeof(LogAdapter<TargetClassB>) };

// Call constructor, decorate optional
var logProvider = new LogProvider(loggerTypes,
    builder => builder.Decorate(TestConfiguration.GetSection("Logging")));
    
// Call loggers
var classAlogger = logProvider.GetLogger<TargetClass1>()
var classBlogger = logProvider.GetLogger<TargetClass1>()

Integrating log4net using log4Net-aspNetCore nuget

var logger = LogProvider._GetLogger<LogProviderTest>(builder => 
            builder.Decorate(TestConfiguration.GetSection("Logging"))
                .AddLog4Net("log4net.config"));
