[jira] [Commented] (LOG4J2-443) log4j2 LoggerContext not showing up
in JMX Gui or JConsole
[ https://issues.apache.org/jira/browse/LOG4J2-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13816996#comment-13816996 ]
Tudor Har commented on LOG4J2-443:
----------------------------------
I got same issue running same Log4J release JMX GUI, on MacOS, same Java version: {code}
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06-451-10M4406)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01-451, mixed mode)
{code}
The same issue happens when I connect remotely, to a server running on CentOS, with slightly older JVM {code}
java version "1.6.0_23"
Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
Java HotSpot(TM) 64-Bit Server VM (build 19.0-b09, mixed mode)
{code}
In both environments, I have couple more logging JARs: {code}
log4j-1.2-api-2.0-beta9.jar
log4j-api-2.0-beta9.jar
log4j-core-2.0-beta9.jar
slf4j-log4j12-1.6.1.jar
{code}

> Key: LOG4J2-443
> URL: https://issues.apache.org/jira/browse/LOG4J2-443
> Project: Log4j 2
> Issue Type: Bug
> Components: JMX
> Affects Versions: 2.0-beta9
> Environment: Java 1.6.0_45-b06 on win7 (same behaviour on Java 7)
> Reporter: Colin Froggatt
>
> This issue raised after request to do so by Remko in [StackOverflow question |http://stackoverflow.com/questions/19816528/log4j2-loggercontext-not-showing-up-in-jmx-gui-or-jconsole].
> I am trying to configure log4j2 so that I can access the loggers via JMX and change their log levels.
> However, when I hook everything up, none of the loggers show up in the JMX tree (or log4j-jmx-gui) as shown in the [log4j2 JMX docs](http://logging.apache.org/log4j/2.x/manual/jmx.html#ClientGUI). Only the log4j2 ContextSelector and StatusLogger in the JConsole attribute tree and the StatusLogger tab in the log4j-jmx-gui (stand-alone or as a plugin) show up. No LoggerContext elements.
> I've googled and not come up with anything! That probably means I'm missing something somewhere. Any help would be greatly appreciated by me and wall which I'm banging my head against :)
> I'm using Log4j2 beta9 with Java 1.6.0_45-b06 on win7. I have tried it on Java 7 and it results in the same behaviour.
