I'm using it via Spring jmx this way :
<bean id="mbeanExporter"
class="org.springframework.jmx.export.MBeanExporter">
<property name="beans">
<map>
<entry key="log4j:hiearchy=default">
<bean
class="org.apache.log4j.jmx.HierarchyDynamicMBean"/>
</entry>
</map>
</property>
<property name="server" ref="mbeanServer"/>
</bean>
This gives me acces to the log4j MBeans to get existing loggers and
change levels. Please note I can ONLY get MBeans for existing loggers,
so I have to define categories in log4j.xml for every logger in my app
that I'd like to configure at runtime.
Maybe next log4j versions will allow a finer JMX management.

Hi all,
I'd like to change the Log4J configuration remotely while my app is
running.
I started a simple JMX solution when I noticed that Log4J already
includes a
JMX package : org.apache.log4j.jmx.
Unfortunately, this package is not well documented, and I could not
find any
mention of it in "The Complete Log4J Manual" (Ceki Gülcü) that I recently
bought.
Could somebody explain me how to use it or point me to some online doc?
I understand that LoggerDynamicMBean, LayoutDynamicMBean and
LoggerDynamicMBean are all wrapper around a Logger, a Layout or an
Appender.
But most of my apps use lots of Loggers, Appenders,... do I have to
publish
a MBean for each of them? Isn't that a bit awkward? If I access them with
jconsole I will end up with lot's of hard to read info. Or is there a
Log4J
JMX GUI client somewhere that present me all that in a friendly way?
Or do I
have to create one? (and if so, is anybody interrested in joining the
project ? :-> ).
Cheers all,
me.
