[logback-user] How to know the filename used by the appender of a given logger

I've made my app know the logger file name so that I can put a link to it in an email. 

Buy the way I did it was to make the app choose the filename and set a system property. Then in logback.xml refer to the system property. 

If that approach does not work, because you are using a dynamic log file name, then I suggest you try subclassing the rolling appender and getting the new filename each time one is generated, and then putting that value into a static singleton that is visible to your app.
