Using JMX to change the log level of a LoggerConfig

[Dave Kriewall <Da...@Attachmate.com>]

I am trying to dynamically change the log level of a given LoggerConfig using jconsole via the JMX interface.  This is currently possible by going to the org.apache.logging.log4j2.Default.Loggers tree in jconsole's MBeans pane, choosing the desired logger, and typing a new Level value (such as "DEBUG") in the "Attribute values" panel.  But it has no effect because LoggerContext.updateLoggers() is not called.  Is there a way to invoke updateLoggers() via JMX?

If not, could LoggerContextAdmin be enhanced to expose updateLoggers() as an action?  Or better, invoke updateLoggers() as a side effect of LoggerConfigAdmin.setLevel() -- which saves a step.

Thanks!
-Dave

Dave,

This has been fixed in trunk and will be in the next release (rc2).

Best regards,
Remko
