It would be great to be able to access JMX, but I am not able to
connect to
the JMX subsystem from my local machine to the servers on AWS.
I have this
<subsystem xmlns="urn:jboss:domain:jmx:1.3">
<expose-resolved-model/>
<expose-expression-model/>
<remoting-connector use-management-endpoint="false"/>
</subsystem>
In the standalone-ha.xml file, and ports 9090 an 8081 open, but I cannot
connect from my machine to the remote server using jconsole with:
service:jmx:http-remoting-jmx://servername:9990 OR
service:jmx:http-remoting-jmx://servername:8081
:-(
