In my project I'm using MVC, NHibernate and for logging html errors I wanna use log4net library.
Here is web.config configuration
<configuration>
<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

In AssemblyInfo.cs file I have this:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]
But in the controller, when I use this part of code, it doesn't create any txt file.
log4net.Config.BasicConfigurator.Configure();
Exception inner = filterContext.Exception.InnerException;
log4net.ILog log = log4net.LogManager.GetLogger("MainLogger");
log.Error("Unhandled exception", inner == null ? filterContext.Exception : inner);
What is the problem?
Try adding this under the root element:
<logger name="NHibernate.SQL">
<appender-ref ref="rollingFile" />
<level value="ALL" />
</logger>
Edit:
In order to use the logger called MainLogger, use this:
<logger name="MainLogger">
<appender-ref ref="rollingFile" />
<level value="ALL" />
</logger>
When in Debug mode, the file will be created in <projectfolder>\bin\Debug, since you did not specify a path but only the filename.

I am using ASP.NET Core and have created a Log4net logging provider.
My current log4net.config file looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="true">
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs\\" />
<appendToFile value="true" />
<DatePattern value="yyyy\\\\MM\\\\dd'.inf.log'" />
<rollingStyle value="Date" />
<param name="StaticLogFileName" value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%ndc] <%property{auth}> - %message%newline" />
</layout>
</appender>
<appender ref="HangfireLoggerAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs\HangfireLog.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="1MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="LogFileAppender" />
</root>
<logger additivity="false" name="Hangfire">
<level value="INFO" />
<appender-ref ref="HangfireLoggerAppender" />
</logger>
</log4net>
The log is showing A LOT of asp.net core junk. SQL Logs ect.
I would like to filter out :
Microsoft.AspNetCore.*
Microsoft.EntityFrameworkCore.*
How do I do this with Log4net?
you need to configure logging on your WebHostBuilder as follows :
[Program.cs -> BuildWebHost(string[] args) ]
return WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
ConfigureLogging((hostingContext, logging) =>
{ logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
logging.AddFilter("Microsoft.AspNetCore", LogLevel.Information);
logging.AddFilter(" Microsoft.EntityFrameworkCore", LogLevel.Information);
logging.AddConsole();
logging.AddDebug();
})
.Build();
You call the logging.AddFilter method specifying the namespace as first parameter and LogLevel as the second parameter.
This can be also done using configuration in appsettings.json file if you don't want to do in code. You can read more here
i am tring to use log4net for log but it is not working
My log file is created empty, without data.
There is no NHibernate data and There is no USER data.
Does anybody know why?
I am tring to do like this:
web.config
<configSections>

</log4net>
On AssemblyInfo
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
On my Helper
log4net.Config.XmlConfigurator.Configure();
log = LogManager.GetLogger("LogEmArquivo");
What is wrong? i already tried many diferent way and the only things that is happining is create the file MyLog_20170303.log with no data.
I keep my log4net config in a seaprate file
Here's my complete file that works.
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="logs/error.log" />
<appendToFile value="true" />
<maximumFileSize value="100KB" />

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\".
In my vb.net project, I use log4net and use an absolute path for the log file. But in the end I need to write log file at C:\Users\UserName\AppData\Local\Temp\Log folder (the username is a variable). Can't find a way how to set this in the log4net file.
My log4net file currently like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<log4net>
<appender name="ExampleAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\Log\App.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="_yyyyMMdd" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level -
[%logger] %message%newline" />
</layout>
</appender>
<logger name="App">
<level value="ALL" />
<appender-ref ref="ExampleAppender" />
</logger>
</log4net>
</configuration>
Is there a way to perform this? thanks.
You can use environment variables like this:
<file type="log4net.Util.PatternString" value="${LOCALAPPDATA}\Temp\Log\App.log" />
This creates a log file (for me) at C:\Users\stuartd\AppData\Local\Temp\Log\App.log
I am using log4Net in my application which also uses nHibernate. Now my eventlogger is flooded with nHibernate messages which I want to suppress.
I have tried this but it did not work.
<log4net>
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
<param name="LogName" value="App Log" />
<param name="ApplicationName" value="DataService" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
<filter type="log4net.Filter.LoggerMatchFilter">
<loggerToMatch value="NHibernate*" />
<acceptOnMatch value="false" />
</filter>
</appender>
<root>
<priority value="ALL"/>
<appender-ref ref="EventLogAppender"/>
</root>
</log4net>
You can add a logger for nHibernate and set up a different level:
<logger name="NHibernate" additivity="false">
<level value="WARN"/>
<appender-ref ref="RollingFileAppender"/>
</logger>
you should use
<loggerToMatch value="NHibernate.*" /> or <loggerToMatch value="NHibernate" />
not
<loggerToMatch value="NHibernate*" />
you can find details in regex rules
I have this in my web.config file (edited to reflect some changes):
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<log4net debug="true">
<appender name="DebugAppender" type="log4net.Appender.AspNetTraceAppender">

I'm calling log4net.Config.XmlConfigurator.Configure() from Application_Start().
I have [assembly: log4net.Config.XmlConfigurator(Watch = true)] in the AssemblyInfo.cs file in my web project.
Why do I get no NHibernate debugging messages in my output window? (I trying to get ALL of the messages that NHibernate spits out.) If I use the RollingFileAppender it works fine. I've tried the DebugAppender, TraceAppender, OutputDebugStringAppender, and AspNetTraceAppender and none of them output stuff to the output window.
Try using a different appender.
ConsoleAppenders probably don't work for web applications. Use something like a FileAppender.
See this for examples on configuraiton.
Similar to quip's answer, ConsoleAppender is not the right appender to use in a web application. An OutputDebugStringAppender will give you messages in your debug window. You may also want to look into AspNetTraceAppender.
You could try to associate the specific NHibernate logger with a log4net appender.
If you want to log all the generated sql, try adding this to your log4net config section:
<logger name="NHibernate.SQL" additivity="false">
<level value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
</logger>
If, for some reason, you only wanted to log Select statements and diagnostic info, you could use NHibernate.Loader.Loader, like this:
<logger name="NHibernate.Loader.Loader" additivity="false">
<level value="INFO" />
<appender-ref ref="ConsoleAppender" />
</logger>
