I tried this. I am able to log to MainLog but not to
OtherLog. But when I add the OtherLogAppender to root,
I am able to log to both logs (unfortunately not
independently). I placed a breakpoint in the
Application_Start method, where I call
DOMConfigurator.Configure(), and it always hits it. So
that's also not a problem.
I have included my code below. If anyone could please
let me know what I am doing wrong, I would be very
grateful. Please feel free to let me know if you have
any questions regarding the code.
Thanks,
Ronnie.
The log4net section of my web.config is as follows:
<log4net debug="false">
<appender name="MainLog"
type="log4net.Appender.FileAppender,log4net" >
<param name="File" value="C:\\Logs\\MainLog.txt"
/>
<param name="AppendToFile" value="true" />
<layout
type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d %-5p
%m%n" />
</layout>
</appender>
<appender name="OtherFeedLog"
type="log4net.Appender.FileAppender,log4net" >
<param name="File"
value="C:\\Logs\\OtherFeedLog.txt" />
<param name="AppendToFile" value="true" />
<layout
type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d %-5p
%m%n" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="MainLog" />
</root>
<logger name="OtherLogger" additivity="false">
<level value="DEBUG"/>
<appender-ref name="OtherFeedLog"/>
</logger>
</log4net>
I declare the logs as follows (in VB .NET):
Private oMainLog As ILog =
LogManager.GetLogger("MainLog")
Private oOtherLog As ILog =
LogManager.GetLogger("OtherLogger")
I log messages like this:
oMainLog.Info("Main Message")
oMainLog.Warn("Main Message")
oMainLog.Debug("Main Message")
oMainLog.Error("Main Message")
oMainLog.Fatal("Main Message")
oOtherLog.Info("Other Message")
oOtherLog.Warn("Other Message")
oOtherLog.Debug("Other Message")
oOtherLog.Error("Other Message")
oOtherLog.Fatal("Other Message")
I configure the logs by using the following code in
the Application_Start method in Global.asax.vb:
log4net.Config.DOMConfigurator.Configure()
