Let me start by saying that I am thoroughly impressed with l4n. I had the
opportunity to see it work in full action when I added it to a serial driver
that was malfunctioning. It filled a file to 400 MB within a couple of
minutes without so much as a hickup. I wrote my own 'logging' utility that
actually caused more problems than the orginal errors because it couldn't
keep up. lol. So anyways, thank you for the great logger. It's impressive
what you have done...
So, that being said, this is probably one of the most painful emails I've
had to write for a while. As I noted above, I have been using l4n in an
application already and have tried to cut and paste to another application,
but I am not getting any output! I even turned on internal debugging and I
can't see any errors. I've done this very thing almost EVERY time I try to
set up l4n again but I never remember what I'm doing wrong... Details to
follow:
App.config settings:
...
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
...
<log4net debug="true">
<appender name="SystemEventInfoLog"
type="log4net.Appender.RollingFileAppender">
<param name="File" value="./INFO/" />
<param name="AppendToFile" value="true" />
<param name="RollingStyle" value="Date" />
<param name="MaxSizeRollBackups" value="10" />
<param name="DatePattern"
value="yyyy/MMMMMMMMM/yyyy-MM-dd.\I\N\F\O"/>
<param name="StaticLogFileName" value="False" />
<filter type="log4net.Filter.LevelMatchFilter">
<LevelToMatch value="INFO" />
</filter>
<filter type="log4net.Filter.DenyAllFilter" />
<layout type="log4net.Layout.PatternLayout">
<Header value="[BEGIN LOGGING AT %date
]%newline "
type="log4net.Util.PatternString" />
<Footer value="[END LOGGING]"
type="log4net.Util.PatternString" />
<param name="ConversionPattern" value="%d -
%m%n" />
</layout>
</appender>
<appender name="SystemLog"
type="log4net.Appender.RollingFileAppender">
<param name="File" value="./SYSTEM/" />
<param name="Threshold" value="ALL" />
<param name="AppendToFile" value="true" />
<param name="RollingStyle" value="Date" />
<param name="MaxSizeRollBackups" value="10" />
<param name="DatePattern"
value="yyyy/MMMMMMMMM/yyyy-MM-dd.\S\Y\S\T\E\M"/>
<param name="StaticLogFileName" value="False" />
<layout type="log4net.Layout.PatternLayout">
<header value="[BEGIN LOGGING AT %date
]%newline"
type="log4net.Util.PatternString" />
<footer value="[END LOGGING]%newline"
type="log4net.Util.PatternString"
/>
<param name="ConversionPattern" value="%d [%t]
%-5p %c [%x] - %m%n" />
</layout>
</appender>
<root>
<appender-ref ref="SystemLog" />
<appender-ref ref="SystemEventInfoLog"/>
</root>
</log4net>
and this is the outline of what I am doing in my classes (note: the throw
statement is just as an example, there would be 'real' code in the try
block):
using System;
using log4net;
public class MyNewClass
{
private static ILog l4nSystemLogger =
LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().Declari
ngType);
public MyNewClass()
{
try
{
throw new Exception("This is an exception.");
}
catch(Exception ex)
{
l4nSystemLogger.Error(System.Reflection.MethodInfo.GetCurrentMethod().Name,
ex);
}
}
}
This works *beautifully* in my other application. What have I missed????
The output should be in
"projectname\bin\debug\SYSTEM\2005\July\2005-07-27.SYSTEM", although I've
search high and low for it on my harddrive.
Thanks for saving my ass once again!
Cheers
