Create a custom evaluator which returns true on events of level ERROR *or* on
events marked with "FLUSH_SMTP".
Before exiting your application you call:
Marker flush = MarkerFactory.getMarker("FLUSH_SMTP");
logger.debug(flush, "Application exiting");
Does it make sense?

Possibly - that is what I was hoping to achieve with hivemodule's Discardable
interface. However, I could just as easily (were the method 'flush' a public
method that would trigger the sending of the email) add something like this
near the end of my application:
Logger EMAIL_LOGGER = LoggerFactory.getLogger("email");
EMAIL_LOGGER.flush();

Hi Jason,
Is there a specific point in your application when you know that it is
about to
be terminated. Put differently, can you call a specific function (to be
discussed later) just before exiting your app?

Here is the behavior I currently observe:
I am using an SMTPAppender to delivery logging messages to my Inbox. By
default, the SMTPAppender implementation that comes with Logback will
trigger the sending of an email (including all accumulated messages) upon
receipt of an ERROR level logging message.
As a result of the default behavior, you can end up in a situation where
you
generate 100 INFO level messages to the SMTPAppender and when your
application exits, no email will have been sent. Those 100 INFO-level
logging messages will be discarded.
Here is the behavior I would like to achieve:
I would like to implement an EventEvaluator or TriggerPolicy that would
force the email to be sent at time of exit or termination. I know that
overriding finalize() is not a reliable method of doing this, as there is
no
guarantee that the VM will actually call it.
I did try using hivemodule's Discardable interface in a subclass of
SMTPAppender, which I use elsewhere in my application, but ran into
problems
with class loaders and the like.
Any suggestions on the best way to achieve this - guaranteed flush/send
of
the email message if there are any unsent events in the queue?
