Introducing My Logging Library

Best practices for getting to continuous deployment faster and with dramatic results in reduced outage minutes, development costs, and QA testing cycles. Brought to you by Rainforest QA.

I’ve just published the first version (consider it a beta) of my logging library to the official nuget server(s).

Why another library when there are existing ones as log4net and nlog? Because it should be easier to get started and you should still have the power to customize the logging if needed. Griffin.Logging do not have a configuration file, everything is configured through code.

Simple syntax

The easiest approach only requires one line to configure the framework:

SimpleLogManager.AddFile(@"D:\LogFiles\MyLog.log");

You can swap the AddFile method to AddConsole if you would like.

Fluent syntax

Use the fluent syntax if you need more power:

var config = new FluentConfiguration()
  .LogNamespace("Fadd.Test").AndChildNamespaces.ToTargetNamed("Console")
  .LogNamespace("System").AndChildNamespaces.ToTargetNamed("DefaultFile")
  .AddTarget("Console")
      .As.ConsoleLogger().Filter.OnLogLevelBetween(LogLevel.Info, LogLevel.Error)
      .Done 
  .AddTarget("DefaultFile")
      .As.FileLogger("ErrorsOnly").Filter.OnLogLevel(LogLevel.Error)
      .As.FileLogger("Everything")
      .Done
  .Build();

Usage

public class MyClass
{
    ILogger logger = LogManager.GetLogger<MyClass>();
 
    public MyClass()
    {
        // Built in formatting for cleaner syntax.
        logger.Info("Welcome {0}!.", user.Name);
    }
    public void HideError()
    {
        try
        {
            throw new InvalidOperationException("No no", new OutOfScopeException("Can't thing anymore"));
        }
        catch (Exception err)
        {
            // Log an exception. The inner exceptions are logged too (recursive)
            logger.Warning("Ooops, we got an exception.", ex);
        }
    }
 
}
