Assuming you set the key-value pair as an MDC entry, this could work
(the filter will be part of log4j1.3 - currently in CVS):
Add to an appender:
<filter class="org.apache.log4j.varia.ExpressionFilter">
<param name="Expression" value="MDC.mykey == 'myvalue'" />
<param name="AcceptOnMatch" value="true" />
</filter>

Hi Jeb,
a way to do this is via implementing the TriggeringEventEvaluator. Try
something like this cheers, Marcel
/***********************************************************************
* SMTP Trigger Event Evaluator
*/
private static class SMTPTriggerEval implements
TriggeringEventEvaluator {
SMTPAppender app;
public void setSMTPAppender(SMTPAppender app) {
this.app = app;
}
public boolean isTriggeringEvent(LoggingEvent event) {
if (event.level.isGreaterOrEqual(Level.FATAL)) {
return true;
} else {
if (app != null) {
// reset the message content
int size = app.getBufferSize();
app.setBufferSize(0);
app.setBufferSize(size);
}
return false;
}
}
}
