How to suppress registration message for nHibernate

Question

I use log4Net in my application which also uses nHibernate. Now my eventlogger is flooded with nHibernate messages that I want to suppress.

I tried this, but it did not work.

<log4net> <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender"> <param name="LogName" value="App Log" /> <param name="ApplicationName" value="DataService" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> <filter type="log4net.Filter.LoggerMatchFilter"> <loggerToMatch value="NHibernate*" /> <acceptOnMatch value="false" /> </filter> </appender> <root> <priority value="ALL"/> <appender-ref ref="EventLogAppender"/> </root> </log4net> 

Answer 1

You can add a registrar for nHibernate and configure a different level:

 <logger name="NHibernate" additivity="false"> <level value="WARN"/> <appender-ref ref="RollingFileAppender"/> </logger> 

Answer 2

you should use

 <loggerToMatch value="NHibernate.*" /> or <loggerToMatch value="NHibernate" /> 

not

 <loggerToMatch value="NHibernate*" /> 

you can find details in regex rules
