Databases – Important Logs can also be stored in a database. Usually, we store only those logs to a database which we need to display in our application. Console – In Console Applications, best available target to display logs is console itself. If you leave it at the default of 100, log4net will wait until you have 100 messages in the queue before it writes them to SQL. If you change that buffer to be 1, it will write a log message immediately like you would expect.
One of the best ways to store log in the database using log4net coz it is easy to use and its world wide popularity. For storing log in the database all task are manage by log4net internally.At first you need to create a table for Storing log in the SqlServer databaseThe table should be like asCREATE 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)1. Download log4net from2. Open visual studio and create an application.3.
Add to the project a reference to the binnet2.0releaselog4net.dll assembly in the log4net distribution.4. Now put this web.config/app.config file in configuration tag. Just want to mention that Log4Net has the possibility to reload configuration dynamically when the config is changed, typical used if you change the log level when the application is running.To activate this you need to use the XmlConfigurator.ConfigureAndWatch instead of XmlConfigurator.ConfigureThe ConfigureAndWatch can be invoked using several methods my personal favorite is using an assembly-level attribute:assembly: log4net.Config.XmlConfigurator(Watch=true)Best regardsGeorg Jansen– Log analysis and monitoring made easy.
Mac,You’ve probably already moved on from your question here, but given that I just had to figure out this problem (found this thread for another purpose), I thought I’d share our solution.The short answer to your question about over-riding the method is yes, you can. I will shamelessly plug the article from which I stole the basis for Log4Net overriding here:Timur Fanshteyn did a fantastic job describing this process, and made it easy for even a C# hack like myself to implement with relatively fast success.That said, I’m not sure that you can, or should, override the method in a manner that returns anything other than void. I’m not sure why I think that (I might have read something about that, or I might just be overly paranoid about altering the method signature), but we came up with a different solution from the one that you’re looking to implement (though we did consider your solution as well).The solution is based around the assumption that the reason you need to have the identity value is because you want to use that to let the customer give you a “handle” to the specific error that they received (through your help desk, or other mechanism). The key there is “error.” The assumption is that you will raise an exception for the condition that you want the customer to see your unique identifier value.

We had long discussions about whether or not it would be valuable to be able to capture the unique ID for an INFO message, or a non-exception containing log message, and determined that we couldn’t think of a use case where that would be valuable.Given that, we chose to subclass the exception class, and assign the exception a unique ID rather than assigning the logged event a “displayable” unique ID. This has a couple of benefits.Subclassing the exception class has benefits on its own, outside of just capturing the unique ID.
Hey guys,For thos of you having a hard time trying to make this work, in my case, I found my solution issuing this within VS.NET immediate window:log4net.LogManager.GetLogger(this.GetType).Error(“test”);It thrown the Sql exception below. I fixed the null issue and it worked like a charm!log4net:ERROR AdoNetAppender Exception while writing to databaseSystem.Data.SqlClient.SqlException (0x80131904): Cannot insert the value NULL into column ‘eventtypeid’, table ‘reduxssptest.dbo.eventlog’; column does not allow nulls.
