Server port with Jconcole on AS 7.1

[sewatech]

Hi,

I've just discovered the new way to connect the jconsole to JBoss AS 7.1.

Now, we have to connect to the native management port (9999). But I do not see a server port anymore. Are we back to an anonymous port ? Or is 9999 the server port too ?

Thanks.

What do you mean by server port?

[sewatech]

In AS 7.0, we had 2 ports

- jmx-connector-registry = 1090

- jmx-connector-server = 1091

Port 9999 replaces the jmx-connector-registry port.

By server port, I mean the replacement for jmx-connector-server.

[dlofthouse]

Ok I understand - no only port 9999 is now needed and used.

TBH I didn't dig too closely into the old impl but in general where services have two ports that is so a client can connect to one port to download a stub that is then used to connect to the second port, now that we use Remoting the JMX URL contains everything needed to connect to the server.

OK, I've tested with a firewall, it's working fine. And -Djava.rmi.server.hostname system property is no more useful with a NAT. It's simply working.

That's great. Thanks.

Is it correct that there is no possibility to connect to a (remote) JBoss 7.0.2 server over JConsole, as this feature is only available in JBoss 7.1?

[sewatech]

No, jconsole acces was already implemented in 7.0.2.

You should check that your config contains the following section :

        <subsystem xmlns="urn:jboss:domain:jmx:1.0">
            <jmx-connector server-binding="jmx-connector-server" registry-binding="jmx-connector-registry"/>
        </subsystem>

And that one :

        <socket-binding name="jmx-connector-registry" port="1090" interface="management"/>
        <socket-binding name="jmx-connector-server" port="1091" interface="management"/>

Hi,

thanks for your reply.

My standalone.xml includes the 2 parts you mentioned above. The management interface is bound to the server's hostname, native management and http management interface have same hosts. I can access the http management console without problems.

But if I try to connect with jconsole, the connection can't be established. I try to connect with the connection string

service:jmx:remoting-jmx://{host_name}:{port}

which I found in a JBoss manual ( https://community.jboss.org/wiki/UsingJconsoleToConnectToJMXOnAS7 ).

Am I missing something?

[sewatech]

That's a manual page for AS 7.1 final. The jconsole access has changed a lot after CR1b.

You have an older version, so you should try with {host_name}:1090 in your jconsole.
