I have a config file to log to a SQL server database.
The logging works fine when I use a sql account, but I need to use a windows account to access the database. Thus I changed the config file to include SecurityContext.
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="data source=SERVER;initial catalog=DB;integrated security=false;persist security info=True" />
<securityContext type="log4net.Util.WindowsSecurityContext">
<domain value ="DOMAIN"/>
<userName value="USER" />
<password value="PASSWORD" />
</securityContext>
But this does not work. I turned on the internal logging and to my surprise I get
log4net:ERROR XmlHierarchyConfigurator: Cannot find Property [domain] to set object on [log4net.Util.WindowsSecurityContext]
But I have defined domain in the securityContext. Why does it not recognize my domain?
After encountering the same problem, I found it's most likely the solution is in renaming the property domain to domainName. For future reference:
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="data source=SERVER;initial catalog=DB;integrated security=false;persist security info=True" />
<securityContext type="log4net.Util.WindowsSecurityContext">
<domainName value="DOMAIN" />
<userName value="USER" />
<password value="PASSWORD" />
</securityContext>
</appender>

Have you tried a simpler log configuration with a static log file name to see if it is your log4net configuration.
You can also turn on internal debugging for log4net to verify your configuration is valid. See this answer here How to track down log4net problems
Maybe are you encountering the LOG4NET-506 issue: latest versions of log4net issue an exclusive mutex named according to file configuration property.
It does not cause issues if the file configuration actually target a file.
But in your case, it is a directory. If you have many processes trying to log to that directory, only one of them will be able of logging.
As a workaround, I have instructed log4net in my cases to log in a Logs\ sub-directory dedicated to each application. Like: file="Logs\App1\".
Description
I have a config file as a resource in my assembly and want to change the ConnectionString programmatically in my application.
I load the configuration using log4net.Config.XmlConfigurator.Configure.
I have some breakpoints and see that the configuration is loaded successfuly and the connectionstring is Data Source=localhost\SQLExpress;Initial Catalog=Log;Integrated Security=SSPI; (local SQLExpress).
Problem
Nothing happens, no exception and no log entry. Any ideas.
using (Stream stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("MyNamespace.Properties.log4net.config"))
{
// stream is NOT null
log4net.Config.XmlConfigurator.Configure(stream);
}
Hierarchy hier = LogManager.GetRepository() as Hierarchy;
if (hier != null)
{
//get ADONetAppender
var adoAppender = (AdoNetAppender)hier.GetAppenders().Where(appender => appender.Name.Equals("AdoNetAppender", StringComparison.InvariantCultureIgnoreCase)).FirstOrDefault();
if (adoAppender != null)
{
// update connectionstring
adoAppender.ConnectionString = configuration.GetConnectionString(ConnectionStringNames.Log).ConnectionString;
//refresh settings of appender
adoAppender.ActivateOptions();
}
}
ILog logger = LogManager.GetLogger("MyProject");
logger.Warn("Test");

You can debug log4net by hooking into the log4net DebugAppender:
Add a log4net app setting in your app.config file:
<appSettings>
<!-- log4net configuration when running in debug mode. -->
<add key="log4net.Internal.Debug" value="true" />
</appSettings>
Add a debug appender in the log4net config:
<appender name="DebugAppender" type="log4net.Appender.DebugAppender">
<immediateFlush value="true" />
<layout type="log4net.Layout.SimpleLayout" />
</appender>
Add the appender to the log4net config root:
<root>
<level value="ALL" />
<appender-ref ref="AdoNetAppender" />
<appender-ref ref="DebugAppender" />
</root>
When you run your application, look in the output window of Visual Studio and you should see all the internal logging for log4net. If not, then the log4net config file is never loading.
Edit
If you can use a connection string from your app.config file, then remove the connection string from the log4net AdoNetAppender and just call the connection string by name:
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<!-- note: you can use the 4.0 assembly -->
<connectionType value="System.Data.SqlClient.SqlConnection,
System.Data,
Version=4.0.0.0,
Culture=neutral,
PublicKeyToken=b77a5c561934e089" />
<!-- This will retrieve a connection string by name from the app.config -->
<connectionStringName value="ConnectionStringNameFromAppConfig" />
<!-- snip -->
</appender>
Here are some things that I tried that worked out for me...
I wasn't seeing anything because my <appender-ref ref="AdoNetAppender" /> didn't properly reference my <appender name="AdoNetAppender" ... /> in the Web.config. The 'AdoNetAppender' names need to match.
Added <bufferSize value="1" /> to the <appender name="AdoNetAppender" /> section of the Web.config
I created a user account with a password on the SQL server instead of using windows authentication. Granted user access to perform selects and inserts on the table
In Global.asax.cs I initialize log4net using log4net.Config.XmlConfigurator.Configure();
In my C# code I instantiate a new adoAppender object and call logger.Info("save to db");
The documentation on Apache's website is helpful as well ...

Hope that saves somebody some time and frustration. Thanks!
I had a log4net configuration running for years, that stopped logging to database this spring 2022.
I solved it by specifying: size value="7" to a DateTime2 database parameter in the log4net configuration. Type in database: datetime2(7), not null.
Why size on that type suddenly is madatory in log4net I don't know.
I am attempting to overhaul one application's (a console app written in VB.NET) logging system using log4net.
I configured log4net according to this CodeProject tutorial. After configuring, I have discovered that the following log initialization creates empty logs (the resulting folder structure is correct and it creates the correct, dated text file, but the file is empty):
Private ReadOnly log As log4net.ILog = log4net.LogManager.GetLogger(Reflection.MethodBase.GetCurrentMethod().DeclaringType)
However, if I use the following line, it logs correctly.
Private ReadOnly log As log4net.ILog = log4net.LogManager.GetLogger("VSED")
In my main module, I'm logging an error like so:
log.Error("Test error!")

Is this even an issue? Will it present problems if I use this logger (explicitly stating its name) in multiple classes as opposed to the reflection?
Essentially, I'd just like to know why it's not working via the preferred method. Is my app.config incorrect? Am I doing something else incorrectly?
Thank you all!
You are only logging messages from VSED, your Reflection.MethodBase.GetCurrentMethod().DeclaringType is probably not VSED, but something.VSED. That is why your logger is not giving any output. See what the Reflection.MethodBase.GetCurrentMethod().DeclaringType is and make a logger with that name.
This will give the output from all your loggers:
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />

I am using this code in WCF application in VS 2012, SQL Express is 2008 R2.
I have included the fileAppendor and Database Appendor, File Appender works fine but its not inserting data into the database.
I have verified the same connection string its working fine and inserting records in to the table.
Also I have set the buffer value to 1, still no luck

Also I am not getting any information by setting Internal.Debug to true.
How to get internal debug details of log4net?
Finaly I got the answer for this, I am sharing here since it may help others.
Need to use the System/Machine Name instead of (local) in the Connection string. Even with the dotnet application (local) works but for log4net need to use the System name.
