What does the MVC baseController with logging look like?

I would like to configure the base controller for my MVC3 application. What my other controllers inherited. What I want to do is do the logging. I saw the following example:

public class baseController : Controller
{

     protected override void OnException(ExceptionContext filterContext)
     {
         filterContext.ExceptionHandled = true;
         this.View("Error").ExecuteResult(this.ControllerContext);
     }

}

But I'm not sure what to register and how to register it. Can anyone give me some tips on what error handling looks like in the base controller. I hope someone can help. Thank.

     Exception exception = Server.GetLastError();
     Response.Clear();

     //Do your logging here.
     //Redirect to an appropriate error page.

        _writer.WriteLine(fullError);
        _writer.Flush();
        _writer.Close();
    }
}

Application_Error ( ) :

new Log().WriteErrorMessage("Global error has occurred.", Request.Url.ToString(), exception);
