Remote fabric fuse container cannot be discovered successfully by JON agent

Solution Verified - Updated -

Environment

  • Red Hat JBoss Fuse
    • 6.0.X
    • 6.1.0
  • Red Hat JBoss Operations Network (JON)
    • 3.1.2
    • 3.2.0

Issue

  • When I installed a remote fabric container and monitor it through JON 3.2.1, the remote container cannot be discovered successfully by JON agent. The error looks like:
JON agent discovers remote Fuse container failed: (org.jbosson.plugins.fuse.FuseServerDiscoveryComponent)- Ignoring resource JBoss Fuse Container
  • Error in agent.log
 ERROR:

  • We have installed JON 3.2 on the server where JBoss Fuse instance is running. Fuse plugin package has been deployed successfully. But JON Agent does not recognise fuse process though both the agent and JBoss fuse JVM runs on the same server under the same Linux user.

Resolution

Diagnostic Steps

  • Red Hat JBoss Fuse 6.0 & Red Hat JBoss Operations Network 3.1.2
    The file name search in the JBoss Fuse plugin matched a part of the name 'fuse' in 'fusefabric' instead of making sure it is a full filename match.
    The relevant information could be found in the agent log in the remote machine:
