As of now you can attach a console appender to ROOT logger so as to also redirect the logs to console but it would not be possible to disable any other FileAppender. So both appender would remain active.
There are ways to override the OSGi based appenders [1] but that would be quite hacky as you would need to do it for each configured appender! To support this case we would need to change the logic to provide such an option Chetan Mehrotra [1] https://sling.apache.org/documentation/development/logging.html#configuring-osgi-appenders-in-the-logback-config On Wed, Feb 3, 2016 at 6:14 PM, Ian Boston <i...@tfd.co.uk> wrote: > Hi, > Is there a master switch in Sling which I can throw to make all logging > appear on stdout regardless of the OSGi LogWriter configuration ?
