Hello.
Your article is very helpful.
But I still have some problem.

My website have several application running under iis.

|-Site_Root
|—-App1
|—-App2
|—-…
|—-web.config

I added log4net configuration in the web.config just as you suggest. There's a log4net.dll in every app's bin folder. But this doesn't work.

If I put a web.config in every app's folder with log4net section in it, logs will be output properly. But I do want all apps can share the root web.config log4net configuration.

Do you have any idea?

Ok. I got solution for the query i've asked before.
Here's the solution

In Log4Net configuration, Instead of putting filename, i've put placeholder for property name as below.

In my Log Class

Logger = LogManager.GetLogger(typeof(Class1));

//Do Impersonation to write files on Shared drive having access to Globalcv user.
//DoImpersonationIfRequired();

log4net.GlobalContext.Properties["LogName"] = ConfigurationHelper.LogFileName.ToString();
//Configuring Object
XmlConfigurator.Configure();

Thanks,
Kaushal

My website is running under asp.net user under IIS. In that i've created one virtual directory as 'Logs' which is internally pointing to my shared drive folder which is access by limited no. of users. Now my question is, how can i create log file on shared folder using log4Net. Is there anyway by which, i'll provide user credentials when i create object of logger & create file or write log information on shared folder.

Regards,
Kaushal

Thanks for your great information.
I am using log4net but in my case isDebugEnabled , IsErrorEnabled etc remain always false. I have searched a lot but nothing could be found.
I am using the below code.
===============================================
Private Shared isDebugEnabled As Boolean = log.IsDebugEnabled

If isDebugEnabled Then
log4net.Config.XmlConfigurator.Configure()
log.Debug("This is debug")
End If
================================================
Please guide me, I am tired after much searching.

Wow!!!,

Super, this is what I was looking for. Thank you!!, I guess I am becoming lazy day by day.
Sharing the knowledge is so easy now a days. Is it good or bad? It is really gooooooooooooooood.

Hi!

I'm a pretty big fan of Log4Net, but what I do find limiting is that there isn't anything in most logging framework that will let me define a custom structure for logging so the data stored can be easily queried later.

I mean, when you've got millions of log entries, you've either got to read through them all or write an insanely powerful text processor. Instead, if you use custom logging you can simply filter the entries by a database column value (assuming you are logging to a DB)
