We are using RHQ version 3 and looking to upgrade to version 4
We have 85 servers and rhq agents running on 34 currently.
We monitor: JBoss5.0.1, Apache 2.2, IIS, currently and would like to add ms-sql, websphere, sharepoint
The number of servers will expand greatly focusing mostly on productions servers.
RHQ server runs on a virtual system, 4Gb mem and 2 CPUs.
Best Practice for upgrading ?
How many systems can RHQ monitor ? - When do I need to cluster RHQ ?
Forcing rhq agents to find existing JBoss instances ? - found two but not the third which was recently installed
Also with experimenting with version 4 - found it very hard to get rid of the memory of a configuration
Finally got so frustrated - i changed the name and the ip addresses of the system
Looking forward to communicating with the rest of the RHQ community

Unsure what this is referring to .. "memory of a configuration". Are you referring to the RHQ Agent's configuration? What name/IP address did you change? Can you be more specific?
I looked at the documentation on the --cleanconfig command, however, in the log file the rhq agent was complaining about being
previously registered with a different name and would not function.
I totally uninstalled postgres and rhq4 and cleaned the file structure but it was still remembering stuff about the previous registration -
Where is it storing this data ?
Essentially I would recommend a switch that really cleans any previous information at the agent and server level.
That would be very helpful during the prototyping phase.
Currently I have an agent that discovered two original instances of JBoss 5.0.1, however, I have not been able to get it to recognize
the new instance of jboss.
I have done an inventory at the server level and also exercised commands at the agent level
I am looking thru the community discussions to learn more
Re: where agent stores config and the "previously registered with a different name" thing, read:
In fact, I would read all of http://rhq-project.org/display/JOPR2/RHQ+Agent+Installation
And this might help too:
along with reading the comments at the top of agent-configuration.xml also explain some things about setting agent config.
We are using RHQ version 4.2 in our company and we think is a great tool. I have a couple of questions about it.
I found that there is a plugin for monitoring JBoss Transaction Service:
It was released in 26 April 2011 but is not included in RHQ v4.2. Do you think is not ready for production usage or... ?
I have another question about an issue using version 4.2, I hope is OK to post it here.
I try to import a resource of type "Process", just like in this demo:
but I get this error: "Failed to manually import resource", with this details:
java.lang.RuntimeException: org.rhq.core.clientapi.agent.PluginContainerException:Failed to add resource with type [Process] and parent resource id  -> org.rhq.core.util.exception.WrappedRemotingException:null -> org.rhq.core.util.exception.WrappedRemotingException:Discovery component invocation failed. -> org.rhq.core.util.exception.WrappedRemotingException:Failed to create process based on plugin config: Configuration[id=0]
Do you know what could that be from ?
Thank you and Best regards,
