- Accessing JMX with jconsole over SSL on EAP 6 https://access.redhat.com/solutions/632773
Internal
Overview
A generic JMX client connects to a standalone EAP 6 instance using the native endpoint of the standalone instance's management interface. For an in-depth explanation on how that works, see Remoting Concepts - Remoting and JMX Access. Specific JBoss libraries must be added to the generic client's classpath, and we will show how those can be added for Visual VM and jconsole. Also, the access must be secured by adding a specific user (or using an existing user) to the management realm, associated with the native management interface.
Server Endpoint
The generic JMX client must connect to the native endpoint of the standalone instance's management interface.
The host address and port binding for the endpoint are specified as "management-native" socket binding, in standalone.xml configuration file:
<socket-binding-group name="standard-sockets" ...>
...
<socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/>
</socket-binding-group>
The port value is 9999.
If the standalone instance runs with a specific port offset, the management endpoint port value must account for that offset.
The actual value for the management interface bind address is specified under the related "management" interface specification:
<interfaces>
<interface name="management">
<inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
</interface>
...
</interfaces>
Unless explicitly re-configured, the default bind address for the management interface is 127.0.0.1.
The bind address and the port are reported as INFO, as follows:
16:15:51,187 INFO [org.jboss.as.remoting] (MSC service thread 1-15) JBAS017100: Listening on 127.0.0.1:9999
The bind address and port will be needed when assembling the URL to be used by the JMX client, below.
Server Endpoint Authentication
A generic JMX client usually provides a username and a password when connecting. Those values must be explicitly added to the Management Realm of the server instance we connect to. The procedure to add a user to the Management Realm is presented in detail here:
Note that no specific group is necessary to be specified during the procedure.
JMX Client
The generic JMX client must add client JBoss libraries to its class path and must set up JBoss specific system properties, as shown below. It also must use a specific URL to connect, and the user and the password configured on the server, as described in the "Server Endpoint Authentication" section.
JMX Client Classpath and Startup Options
The JBoss JAR $JBOSS_HOME/bin/client/jboss-cli-client.jar must be added to the JMX client classpath. Also, the JMX client must be started with -Dmodule.path=${JBOSS_HOME}/modules. Specific details for a number of clients are available below:
URL
Use:
service:jmx:remoting-jmx://<server-host>:9999
where <server-host> is the interface the native management endpoint is bound to. If the client and server are collocated, that is usually 127.0.0.1.
Authentication
Use the username and the password configured on the server, as described in the "Server Endpoint Authentication" section.
SSL Connection Configuration
