Description Larry O'Leary 2012-07-18 00:57:31 UTC

+++ This bug was initially created as a clone of upstream RHQ project Bug #841047 +++

Description of problem:
Managed servers do not get discovered when domain or host controller's unique identified/name is determined at runtime instead of being specified in the host.xml configuration file. The only thing logged in the agent is:

DEBUG [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Executing discovery for [Managed Server] Resources...
DEBUG [ResourceDiscoveryComponent.invoker.daemon-2] (rhq.modules.plugins.jbossas7.ASConnection)- Requested management resource not found: host=master
DEBUG [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Discovery for [Managed Server] resources completed in [55] ms


In this case, the plug-in is looking for a host named master even though the host configuration name is equal to $(hostname)

Version-Release number of selected component (if applicable):
RHQ 4.4.0.JON310GA

How reproducible:
Always

Steps to Reproduce:
1.  Install EAP 6 and prepare it for use with JON
2.  Edit domain/configuration/host.xml and remove the naem="master" attribute from the host element
3.  Start EAP using domain.sh
4.  Start JON system
5.  Add EAP 6 server to inventory
  
Actual results:
After discovery has been executed, no managed servers appear in inventory and the following messages appear in the agent log when debug is enabled:

DEBUG [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Executing discovery for [Managed Server] Resources...
DEBUG [ResourceDiscoveryComponent.invoker.daemon-2] (rhq.modules.plugins.jbossas7.ASConnection)- Requested management resource not found: host=master
DEBUG [InventoryManager.discovery-1] (rhq.core.pc.inventory.InventoryManager)- Discovery for [Managed Server] resources completed in [55] ms


Expected results:
The managed servers `server-one` and `server-two` should appear in inventory and the debug log should reflect that the new managed servers have been discovered and added.

Additional info:
AS7 does not require a name attribute for the host configuration in host.xml.

As of version 1.0[1] of the configuration schema release, this attribute is optional and if not provided will default to the runtime value of InetAddress.getLocalHost().getHostName(). As of schema version 1.3[2], this attribute is still optional but a different default value path is being taken.

Moving to ON_QA since JON 3.1.1 ER2 build is availble - https://brewweb.devel.redhat.com/buildinfo?buildID=228250

Comment 4 Sunil Kondkar 2012-08-23 11:00:21 UTC

Verified on JON 3.1.1.ER3 build

Followed the steps (removed the name="master" attribute from the host element in host.xml file ) and verified that the managed servers `server-one` and `server-two` appear in inventory and the agent log displays that the new managed servers have been discovered.
