Pierrick HYMBERT commented on LOG4J2-1910:
------------------------------------------
You may register a
{{org.apache.logging.log4j.core.config.ConfigurationListener}} in your custom
configuration by calling
{{org.apache.logging.log4j.core.config.AbstractConfiguration.addListener(ConfigurationListener)}}
within doConfigure method, then you will be notified when the file changed and
apply again your programatic configuration.
> On changing of log4j2.xml, the CustomConfig and Factory are not called and
> custom loggers are lost

> We created Custom Configuration(Log4JConfiguration) and Factory by following

> Initialize Log4j by Combining Configuration File with Programmatic
> Configuration,
> On application initialization, everything works ok and log events are logged
> to custom logger file, but on changing of log4j2.xml file which is set to
> monitorInterval="10", Custom Log4JConfiguration is not called
