SmtpAppender and EventLogAppender

Hello,
I'm doing a windows service which uses a SmtpAppender and an 
EventLogAppender. The EventLogAppender logs all messages which level is 
greater or equal to DEBUG, the SmtpAppender all messages which level is 
greater or equal to ERROR. Now if I try this :

ILog logger = LogManager.GetLogger(this.GetType());
logger.Info("Info 1");
logger.Info("Info 2");
logger.Error("ERROR !!!!!!!");

I receive a mail message which contains :

Info 1
Info 2
ERROR !!!!!!!

but I'd like only :

ERROR !!!!!!!

Can you help me please ? Here a part of my App.config :

<!-- Informations requises par log4net. -->
<log4net>

<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
<applicationName value="Serveur AP+" />
<logName value="APPlus" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message%newline%exception" />
</layout>
</appender>

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="*************" /> <!-- Liste des adresses e-mail (séparateur : 
point-virgule) auxquelles seront envoyées les erreurs survenues. -->
<from value="*************" />
<subject value="[AP+] Une erreur est survenue" />
<smtpHost value="*************" />
<bufferSize value="512" />
<lossy value="false" />
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="ERROR"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message%newline%exception" />
</layout>
</appender>

<root>
<level value="DEBUG" />
<appender-ref ref="EventLogAppender" />
<appender-ref ref="SmtpAppender" />
</root>

<!-- Ceci permet de désactiver le logging des messages provenant de 
NHibernate. -->
<logger name="NHibernate">
<level value="OFF" />
</logger>

</log4net>

Setting the appender's threshold property should also work:

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
 <to value="*************" />
 <from value="*************" />
 <subject value="[AP+] Une erreur est survenue" />
 <smtpHost value="*************" />
 <bufferSize value="512" />
 <layout type="log4net.Layout.PatternLayout">
  <conversionPattern value="%message%newline%exception" />
 </layout>
 <threshold value="ERROR" />
</appender>

Nicko, what is the difference between threshold and evaluator?

 <evaluator type="log4net.Core.LevelEvaluator">
  <threshold value="ERROR"/>
 </evaluator>

 <threshold value="ERROR" />

Does one discard messages sooner than the other?

Re: SmtpAppender and EventLogAppender

Try using the applying the following level filter to achieve that:

<filter type="log4net.Filter.LevelRangeFilter">
    <levelMin value="ERROR" />
    <levelMax value="FATAL" />
</filter>

Use the above filter filter element in your SmtpAppender configuration
and see.

Thanks,
