Question

I want INFO for everything and DEBUG for one package. I’ve tried numerous variations of:

<log4net>
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
        <param name="File" value="C:/temp/AutoTag.log"/>
        <param name="AppendToFile" value="true"/>
        <param name="MaxSizeRollBackups" value="2"/>
        <param name="MaximumFileSize" value="100KB"/>
        <param name="RollingStyle" value="Size"/>
        <param name="StaticLogFileName" value="true"/>
        <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%d [%t] ac.server %-5p %c - %m%n"/>
        </layout>
    </appender>
    <root>
        <level value="INFO"/>
        <appender-ref ref="RollingFileAppender"/>
    </root>
    <logger name="AutoTagCore.net.windward.autotag.utils">
        <level value="DEBUG"/>
    </logger>
</log4net>

But nothing works. If I remove the <root/> part, I get the detailed in the one package. Otherwise it’s as though the <logger/> part is not there.

How can I accomplish this? (Updated to show full log4net part).

Update2: I’m an idiot – I had the wrong package name in there.

Answer 1

Logger will inherit all appenders from root. You need to specify level only:

<root>
    <level value="INFO"/>
    <appender-ref ref="RollingFileAppender"/>
</root>
<logger name="AutoTagCore.net.windward.autotag.utils">
    <level value="DEBUG"/>
</logger>

BTW Verify appender settings – it could be restricted to INFO level:

<threshold value="INFO"/>

And last possible issue – you can have different type namespace and logger name (maybe some typo).
