    JON Server Dashboard not showing jboss instances

    Cathy Degagne Newbie

      I've installed a JON Server and 2 agents. The JON Server and 1 agent is on server A and the other agent is on server B. I have 4 jboss instances on server A & server B. They are clustered. The install is mostly all the default settings except for the ip addresses for the agents, JON Server and the Oracle DB setup. No other settings have been changed. I can see the agents along with the file system, network adapters and cpu but none of my JBoss instances are appearing in the Dashboard. I've installed the plugins for SOA and EAP. I've run the discovery on the agents.

      I'm also receiving these errors in my jon server log. I've removed our ip address and replaced the names of the agents and servers for security purposes.

      The plugins these errors are referring to are installed on the agent and server.
      We are using JBoss SOA P 4.3 and JON 2.2.

          I ended up reinstalling my JON Server and agents and it cleared up those errors. I'm able to see my RHQ Agent now, however, I'm still not seeing my jboss instances. I am getting some odd warnings in the log of one of my agents.

            This problem was finally resolved. I had to change the ownership of my Agents to match my instances.
