I'd like to redirect everything logged by log4net to the System.Diagnostics Trace classes. My understanding of what I should be doing is pointing log4net at system.diagnostics.traceappender, then I configure system.diagnostics. Here's important parts in my web.config:
<log4net>
<appender name="trace" type="log4net.Appender.TraceAppender, log4net">
<immediateFlush value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern"
value="%d{ABSOLUTE} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<root>
<priority value="DEBUG"/>
<appender-ref ref="trace"/>
</root>
</log4net>
<system.diagnostics>
<sources>
<source name="Console" switchName="DefaultSwitch">
<listeners>
<add type="System.Diagnostics.DefaultTraceListener" name="Default">
<filter type="" />
</add>
</listeners>
</source>
<source name="Metabase" switchName="MetabaseSwitch">
<listeners>
<add name="MetabaseListener" />
<remove name="Default" />
</listeners>
</source>
<source name="TextFile" switchName="TextFileSwitch">
<listeners>
<add name="TextFileListener" />
<remove name="Default" />
</listeners>
</source>
</sources>
<sharedListeners>
<!--<add name="ConsoleListener" type="XXX.Manufacturing.Utilities.Diagnostics.ColorConsoleTraceListener,XXX.Manufacturing.Utilities" />-->
<add name ="TextFileListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="TextFile.log" />
<add name="MetabaseListener" type="XXX.Manufacturing.Utilities.Diagnostics.MetabaseTraceListener,XXX.Metabase.Proxies" />
</sharedListeners>
<switches>
<add name="MetabaseSwitch" value="Information" />
<add name="DefaultSwitch" value="Verbose" />
<add name="TextFileSwitch" value="Verbose"/>
</switches>
</system.diagnostics>
Did I miss a crucial step linking things up? If I bypass log4net and just create a new tracesource it will log to my sources.
Did you call the XmlConfigurator.Configure();
method?
If that is not the problem then you can either turn on internal debugging (explained here) or maybe configure a console appender and see if that is working.
Edit: I am not that familiar with the trace system, but if you configure a trace listener as follows you should get the log4net output:
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\temp\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>
