Jörg Bretschneider updated LOG4J2-1192:
---------------------------------------
Description:
It is annoying to have log messages sent to users via SMTP Appender with a
static subject, requiring recipients to open each of possibly a vast amount of
log emails in order to find out what went wrong.
Users should be able to insert runtime diagnostic context information to the
message text AND to the message subject as well.
While the first seems to be working with Patternlayout using the mechanism with
the %X{<key>} pattern based on a NDC or MDC <key> in the "ConversionPattern"
parameter, it does NOT work with the "Subject" parameter with log4j (neither
1.2 nor 2.x), though some bloggers suggest it, e.g.
http://stackoverflow.com/a/7015453.
See
http://stackoverflow.com/questions/29435825/log4j2-custom-email-subject-from-map
as an example where others found this also.
This issue should have been fixed long ago.
I suggest to extend SMTP appender in order to be able to use %X and other
Pattern conversion in the "Subject" parameter properly.
http://openutils.sourceforge.net/openutils-log4j/smtpappender.html
has already done the part for applying PatternLayout to the SMTP Appender
"Subject". I didn't test of this works properly.
Maybe this work can be included into log4j with minimal effort?
