Configure Nhibernate log into file - nhibernate

Question

I have programmatically create log4net log from config file:
var properties = new NameValueCollection
{
{"configType", "FILE"},
{"configFile", #"c:/log4net.config"}
};
Common.Logging.LogManager.Adapter = new Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter(properties);
This is my log4net.config (EDITED for simplicity as dove suggested) :
<log4net>
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="c:/log.log" />
<appendToFile value="true" />
<maximumFileSize value="100KB" />
<maxSizeRollBackups value="5" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d [%t] %-5p %c - %m%n" />
</layout>
</appender>
<root>
<level value="All" />
<appender-ref ref="RollingFile" />
</root>
<logger name="NHibernate">
<level value="All" />
<appender-ref ref="RollingFile" />
</logger>
</log4net>
I got Spring.NET successfuly logging into that file, but not NHibernate.
Nhibernate is configured fluenltly:
protected override void PostProcessConfiguration(Configuration config)
{
base.PostProcessConfiguration(config);
var msSqlCfg = MsSqlConfiguration.MsSql2000.ConnectionString(ConnectionString)
.ShowSql();
Fluently.Configure(config).Database(msSqlCfg)
.Mappings(m => m.FluentMappings.Add<EmployeeMap>())
// Other mappings
.BuildSessionFactory();
}
What should I fix to get Nhibernate log working?

Answer 1

Does it log if you generate statistics?
Configuration.ExposeConfiguration(c =>
c.SetProperty("generate_statistics", "true"));
To narrow things down can you remove additivity flag and appeder from within logger and just log one to start, i.e. exactly like this
<logger name="NHibernate">
<level value="ALL" />
</logger>
