[slf4j-user] user Digest, Vol 26, Issue 1

[Ceki Gulcu]

Hello Thomas,

I see. You could retain the current functionality by setting up a
SMTPAppender which is triggered (i.e. sends out an email) whenever a
logging event marked as FATAL occurs. You need to use SLF4J
markers. Moreover, currently only logback supports markers (wheras
log4j and j.u.l. do not support markers).

The usage pattern could be:

   Marker FATAL = MarkerFactory.getMarker("FATAL");
   logger.error(FATAL, "some serious error", exception);

You can of course store FATAL as a constant somewhere in your
applicaiton. The pattern then becomes

   logger.error(MyContstants.FATAL, "some serious error", exception);

I could supply the SMTPAppender configuration if you were intersted in
this venue.

HTH,
