As far as I know, the JMX service on wildly is accessible on port 9990. From your mail, it seems that it's running at 10990 for you.

To access WildFly over JMX remotely through jconsole following are the steps you need to follow:

1. On the wildfly server, create management user using add-user.sh.
2. Get the jboss-cli-client.jar from the wildly server to your local laptop (from where you are planning to launch jconsole).
3. Invoke the following from your local laptop to start jconsole:

$JAVA_HOME/bin/jconsole -J-Djava.class.path=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/jconsole.jar:/jboss-client.jar &

1. On the jconsole pop up window which comes up on your laptop, select "Remote Process". Provide the following URL:

service:jmx:http-remoting-jmx://WildFly_Host:JMX_Port

For example, it could be : service:jmx:http-remoting-jmx://1.2.3.4:9990

1. Provide the username and password created in step #1.
2. Connect.
