[logback-user] Setting MDCFilter values at runtime

[Ralph Goers]

You need to use Logback's ability to reconfigure itself to change the value at runtime.  Just set scan="true" and change the file.

Basically, if there's a problem reported, I want to be able to use JMX or some other means to tell log back to start logging all messages for user X (an MDC value) at DEBUG and then later revert back to normal logging.

Basically, if a specific user is having trouble, I want to set their logs to show up as DEBUG while the remainder of the logs show up as INFO.  Is there a way (preferably using JMX) that this can be done via configuration?  If not, what's the best approach programatically?
