Hello, I am testing the solution but Log4Net is not logging errors in the database. Can you help me please?

Oct 28, 2011 at 9:29 PM

I too was having problems getting the Log4Net logging to go into the database.

It turns out, the database table called "Log" was not created when the initial MyFinance table was created.

You can go to this page: http://logging.apache.org/log4net/release/config-examples.html.

On that page, use the SQL script to create the Log table:

CREATE TABLE [dbo].[Log] (   

[Id] [int] IDENTITY (1, 1) NOT NULL,   

[Date] [datetime] NOT NULL,   

[Thread] [varchar] (255) NOT NULL,   

[Level] [varchar] (50) NOT NULL,   

[Logger] [varchar] (255) NOT NULL,   

[Message] [varchar] (4000) NOT NULL,   

[Exception] [varchar] (2000) NULL)


And then modify the web.config file for the <log4net> element to add the extra parameter for the exception item. The Apache link I supplied above shows what you need to change to match.

Once you set these up, the logging works great! I have confirmed it.

I did it, but still doesn't work. This is my web.config:

Hi japonte,

Well, there's one more piece to the puzzle. It turns out, the original project doesn't actually have any logging turned on.

So, to test it out, I updated the HomeController.cs to add the special logging attribute called UserTrackerLogAttribute.

To see how I used it, here's my updated HomeController.cs with the UserTrackerLogAttribute added to the default Index action:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MyFinance.Service;
using System.Web.Helpers;
using System.Globalization;
using MyFinance.Data;
using MyFinance.Data.Infrastructure;
using MyFinance.Web.Helpers;
namespace MyFinance.Web.Controllers
    public class HomeController : Controller
        public ActionResult Chart()
            return null;
        public ActionResult Index()
            return View();
        public ActionResult About()
            return View();


If you add that attribute and then run the app (assuming your web.config is all updated and you have the Log table created properly

in your SQL Express system), you should get a log entry generated each time you load the Index page.

Thanks, It works, but the field Log.Exception doesn't store exception details.

Oct 31, 2011 at 4:29 PM

Hi japonte,

That's because the [UserTrackerLog] attribute calls the LoggingService.Log(string) method so it doesn't pass an exception object to be recorded.

Log4Net has a lot of power and capabilities so if you want to log exceptions in your own code, you would have to write some of your own logging code.

Get a reference to the Log4Net object (see the LoggingService.cs class to see how they do it), and then call the logger with whatever level of logging

you'd like (Debug, Error, Fatal, Info, Warn) and pass the Exception type object to the logger when you're inside your catch{} clause.

None of this code is written in the sample application provided. This sample only shows a few basic techniques, the rest you have to write yourself.

Thank you very much, Oakmario.
