Configure NHibernate Log seperately to applications log

Hi devmates,

of course i tried the search-field first, but couldnt find something pointing my problem.

I am trying to configure the nhibernate logger seperately to my applications log, as described in the subject ;).

Code:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="System.Configuration.IgnoreSectionHandler" />
  </configSections>

  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Logs\Framework.log" />
      <appendToFile value="true" />
      <maximumFileSize value="30MB"/>
      <maxSizeRollBackups value="5"/>
      <rollingStyle value="Composite" />
      <datePattern value="-yyyy-MM-dd.lo\g" />
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %-5level %logger - %message%newline" />
      </layout>
    </appender>

    <root>
      <level value="WARN" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
  </log4net>
</configuration>

So, if i configure the log value to any value, the nhibernate logger logs everything it cans. Is there any way to disable the logs from nhibernate and keep my own log´s in my application alive? Or at least i would like to say:

Hey, NHibernate´s Logger, please just log your Warnings or Errors and Hey Application´s Logger, you can log on INFO.

Hope you understand my problem.

best regards
ap

Add this:

Code:

    <logger name="NHibernate">
      <level value="WARN" />
    </logger>

    <logger name="NHibernate.Cfg">
      <level value="OFF" />
    </logger>

    <logger name="MyApp">
      <level value="DEBUG" />
    </logger>

For application logging you then can use:

LogManager.GetLogger( "MyApp" );

Or if you want it to based on the namespaces (gives you much more flexibility for configuring logging for debugging):

Code:

     private static readonly ILog log = LogManager.GetLogger( MethodBase.GetCurrentMethod().DeclaringType );

    <logger name="some namespace from my app">
      <level value="DEBUG" />
    </logger>

[/code]

For more info I recommend the log4net documentation.
