JBoss Domain JConsole connection

JBoss EAP is shipped with its own JConsole, so you can get insight about your server via JMX.
In this post I´ll talk about domain mode in JBoss EAP 6.2.

JConsole is in ${JBoss.home}/bin/jconsole.sh

Topology

This is my topology:

• Domain Controller in 192.168.56.101
• Host Controller 1 in 192.168.56.102
• Host Controller 2 in 192.168.56.103

I Have a server-group called jbossEAP6-sg1 with two servers, each one in its own HC:

• server-full-ha-1 in HC 1, bound to 192.168.56.130
• server-full-ha-2 in HC 2, bound to 192.168.56.140

This domain is in a CentOS remote PC and I Will connect from my Windows installation.

Configuration

I want to monitor Domain Controller in general, and my servers in particular. So I will make two different connections.

You have to configure jmx subsystem in domain.xml (this file is placed inside de Domain Controller). Once there you have to set the following config:

<subsystem xmlns="urn:jboss:domain:jmx:1.3">
 <expose-resolved-model/>
 <expose-expression-model/>
 <remoting-connector use-management-endpoint="false"/>
</subsystem>

Then, you need an application user in all the nodes (asuming you already have a management user in the domain). Simply use ./add-user.sh in DC, add a user, and copy the application-roles.properties and  application-users.properties files in the others HCs.

Connection to DC

You can start your connection with the followning parameters:

• Remote Process: service:jmx:remoting-jmx://192.168.56.101:9999
• Username/Password: domain user

Note that there is a CLI tab due to this is a DC.

Connection to server-full-ha-1 in HC 1

You can starts your connection with the followning parameters:

• Remote Process: service:jmx:remoting-jmx://192.168.56.130:4447
• Username/Password: application user

Note that in this case you need to set de 4447 port. I'm using a custom binding address for each server, so I don´t need to specify a port offset, otherwise you need to calculate the real port of your server.
