log4j and jmx

[mischa <mi...@gmail.com>]

hi,

are there any good examples how to setup log4j via jmx?
i am using my own jmx service based on mx4j and wonder what steps are 
needed to register a
LoggerDynamicMBean for my service.

I'm using Spring BeanExporter to publish log4j configuration

    <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>

MBeanExporter simply register the HierarchyDynamicMBean bean into my 
MBean server using "log4j:hiearchy=default" ObjectName.

MBeans are created for root logger, appenders and logger's hierarchy

Then I use MC4J console and invoke 'addLogger' to add a logger MBean for 
a pre-existing category. I can change logs level at runtime on this logger.


Something I think is missing is the ability to add a logger MBean for a 
category that is not pre-existing in log4j configuration. This may be 
usefull to set a simple package / class in debug on a running server. 
Current implementation requires me to setup empty categories for every 
potentialy interesting packages in my log4j.xml
