---------------------------------------

             Summary: Clear log
                 Key: WFLY-10935
                 URL: https://issues.jboss.org/browse/WFLY-10935
             Project: WildFly
          Issue Type: Feature Request
          Components: Logging
            Reporter: Olivier Cailloux
            Assignee: James Perkins
            Priority: Minor


When debugging it’s handy to be able to easily clear the log just before triggering an action that makes an application misbehave (so that you can then inspect the log knowing that it starts when the action starts).

For this, it would be nice to have the possibility to force rotate the log on the periodic-rotating-file-handler type of handler.

Thus we would run something like this in the CLI: /subsystem=logging/periodic-rotating-file-handler=FILE:write-attribute(name="rotate", value=true)

Maybe it’s already possible by writing the "enabled" or "change-file" or "append" attribute (twice, to put it back to its previous state), but it feels hackish and it’s undocumented, therefore I’m not sure what the side effects of this would be (even assuming it would work).

GlassFish for example has [asadmin rotate-log|https://github.com/oliviercailloux/java-course/blob/master/GlassFish.adoc#clear-log].
