JBossAS7.1.1 and log4j configuration (externalize and automatic reload)

jmcollin92 Mar 22, 2013 6:02 AM

Hello,

When I was working with JBoss as 4.x, it was possible to modify a jboss-log4j.xml file in $JBOSS/server/default/conf. This file was automatically reloaded and taken into account at runtime. Very usefull to dynamically change log level to make some production issues analysis.

My question is : how to do the same with JBossAS 7.1.1 ? The log4j conf is embedded in the standalone.xml, there is a logging:properties which is not used after booting. I read https://docs.jboss.org/author/display/AS71/Logging+Configuration carefully and also search in this forum without success.

For information, i'm using slf4j in ejb jar and war(s).

Thanks for your advice.

JM.

One way, but it is not really what is asked, is certainly to change logging configuration by admin console.

The way to do that in JBoss AS 7 is with the logging subsystem. JBoss AS 7 does not use log4j. There could be other ways using other log managers and setuping listeners of some sort, but since you're using slf4j I would suggest just using the logging subsystem.

The only problem I see is that we do change in a common file to all applications. When having multiple applications, it is safier that each application has its own config file. OK, I understand there is no simple solution, so I will continue with the admin console.

With EAP 6.1.Alpha you can use logging profiles if you want each application to have it's own log context.
