Changing log level
The easiest way to change the logging level is to set the new level on the root logger.
The levels defined are Off, Fatal, Error, Warn, Info, Debug, All
E.g.
<log4net>
...
<root>
<level value="WARN" />
Prohibit logs to a specified log appender
<log4net>
<appender name="RollingFileAppender"
type="log4net.Appender.RollingFileAppender">
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="WARN" />
<levelMax value="FATAL" />
</filter>
...
Tips: Never set a log level to OFF, it’s better to use the recommended production value WARN. So you don’t filter away any important messages on your developing machine.
Adding thread information to your log file
If you want to se what log messages are in the sqame thread you can add the [%thread] argument to your log appender in the EPiserverLog.config file.
E.g.
<appender name="fileLogAppender" type="log4net.Appender.FileAppender" >
...
<conversionPattern value="%date %level [%thread] %type.%method - %message%n" />
Look at WCF logs

initializeData= "C:\temp\Log\Traces.svclog" />
</listeners>
