Can we create separate log files each time when the application is run? If i run my application 2 times, I should get 2 separate log files, hopefully the file names can be appended with the created dateTime
eg:
log_0830 - when application is run on 8:30 am
log_2130 - when application is run on 9:30 pm
Put that into your app.config:
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<appender name="file" type="log4net.Appender.RollingFileAppender">
<file value="log_"/>
<rollingStyle value="Date"/>
<datePattern value="HHmm.\tx\t"/>
<staticLogFileName value="false"/>
<appendToFile value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level %message%newline" />
</layout>
</appender>
<root>
<level value="ALL"/>
<appender-ref ref="file"/>
</root>
</log4net>
That configuration would produce filenames:
log_0830.txt - when application is run on 8:30 am
log_2130.txt - when application is run on 9:30 pm
I believe you could do this in the configuration like so:
<appender name="LogFileAppender" type="log4net.Appender.FileAppender">
<file type="log4net.Util.PatternString" value="log-file-%d [%t].txt" />
<layout type="log4net.Layout.PatternLayout" value="%date [%thread] %-5level %logger - %message%newline" />
</appender>

I am using following log4net.config file:
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value= " D:\Logs_Event\log_event.txt"/>
<staticLogFilename value = "false"/>
<appendToFile value="true"/>
<datepattern value = "yyyy-MM-dd"/>
<rollingStyle value="once"/>
<layout type = "log4net.Layout.PatternLayout">
<conversionPattern
value="%date [%thread] %-5level %logger ==> %message%newline"/>
</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="AdoNetAppender" />
</root>
</log4net>
When the application starts, I have to log all events in text files till the application ends. If the application starts next time the events will get logged into another text file with the respective date format. How can I achieve this?
You can achieve this using the PatternString option provided in log4Net.
<file type="log4net.Util.PatternString"
value="LogFileName_%date{dd_MM_y(hh:mm:ss)}.log" />
check here for the date conversion pattern and here for Date time formatter.

I have a web project and a console project. I've published my web project on Azure (after having the console app attached as a Azure Webjob to the web project).
Now I want to use Log4net to log in files. It works for the web project but I can't get it to work for the Webjob...
Here is my log4net config :
<log4net>
<appender name="FileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="./_logs/[%date{yyyy-MM-dd-HH}]_webjob.log" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="4096KB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline %date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
<logger name="myloggername">
<level value="ALL" />
<appender-ref ref="FileAppender" />
</logger>
Some guy said it would work with a absolute path but it doesn't :
<file type="log4net.Util.PatternString" value="D:/home/site/wwwroot/App_Data/Logs/AccountMaintenance/log4net_%date{yyyyMMdd}.log" />
Please try the following value instead:
<file type="log4net.Util.PatternString" value="d:\home\logfiles\mylogfile.log" />
Our application uses log4net to write some logs to the local disk with RollingFileAppender. It runs well in local developing machines until we test it with remote desktop connection in virtual machines.
After install it in Win8, we have to run it as administrator to let it write logs. Even if we login the remote win8 with a local administrator account of the win8.
Things are different in win7. The application always writes logs even if we login the remote win7 with a domain user. Maybe you are interested in the config file, let me put it here:
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="c:\mylogfile.txt"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="5"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
</layout>
</appender>
<root>
<level value="Debug"/>
<appender-ref ref="RollingFileAppender"/>
</root>
Your user does not have permissions to write to c:\mylogfile.txt. Make a directory c:\temp and try to log to c:\temp\mylogfile.txt
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="c:\temp\mylogfile.txt"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="5"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
</layout>
</appender>
<root>
<level value="Debug"/>
<appender-ref ref="RollingFileAppender"/>

Trying to get log4net setup for .net 4.0 asp.net mvc2 app. I have bare minimum configuration but nothing is getting logged. Am I missing something?
referencing log4net 1.2.10 released version dll
added in sections
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
added section
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<!-- Pattern to output the caller's file name and line number -->
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="c:\\example.log" />
<appendToFile value="true" />
<maximumFileSize value="100KB" />
<maxSizeRollBackups value="2" />
<layout type="log4net.Layout.PatternLayout">

</layout>
</appender>
<root>

<appender-ref ref="Console" />
<appender-ref ref="RollingFile" />
</root>
</log4net>
trying to log message with log4net.LogManager.GetLogger("global").Error("test error");
But there is nothing getting logged and no error. Tried lot of config variations like only console, only rollingfile, to file appender only. but nothing works. And yes it's .net 4.0 full project not client profile.
What could be wrong in here?
Did you start log4net?
protected void Application_Start()
{
XmlConfigurator.Configure();
...
}
I didn't want to make the title too long but this question specifically refers to running an NServiceBus Generic Host as a Windows Service (thanks to TopShelf) configured to run as Local System (on a Vista machine)
In a previous question I explain why I decided to adapt the PubSub sample to run as a Windows Service so that I can easily stop and start the service to fully prove to myself that NServiceBus was doing what it was supposed to do.
For some reason I can't get Log4Net to log anything to disk, so this could well just be a Log4Net (newbie) configuration problem?
Below is my brute-force attempt to get some sort of tracing going - all I'm getting so far is files writen as follows:

NSB will not pick up log settings from config files as default. To do this implement IConfigureLogging in your endpoint config class.

Hope this helps!

It looks as if your other two appenders are throwing exceptions while trying to log. I suspect the %property{NDC} in your patterns - remove them from the pattern and try again.
If your pattern contains %property{X} then you need to set a property with key "X" using code such as
ABC.Properties["X"] = /* some value */
where ABC is either a LoggingEvent instance or ThreadContext or GlobalContext.
I don't know if you've set properties with key "NDC", but I suspect not...
