Hello,
I'm posing this question here as I think this list will have the most
knowledgeable people about RHQ. This is a bit of an end user question
though.
We're looking at using RHQ/JON to monitor VMs. I have set up a template
for VMs that has jboss EAP 5.0 and rhq-agent. What I'm running into is
that it takes a long time for a up/down status change on the Jboss to
register with the JON server. I'm shutting down JBOSS and just waiting
for JON to get the news. in the agent.log I see this which seems to be
the moment the news is sent from the agent:
2010-01-27 16:36:07,365 INFO [InventoryManager.availability-1]
(rhq.core.pc.inventory.InventoryManager)- Sending availability report to
Server...
I believe this was five or ten minutes after I shut down the Jboss, the
log file is a little hard to go through but that's about what it seems.
I was watching the reload timer on the resource page in JON waiting for
it to finally realize the resource was unavailable.
Is there a configuration I can do on the agent or server to make it
react faster to time outs?
I have tried to do it with the agent-configuration.xml in the agent/conf
directory but it doesn't seem to have made it any faster.
TIA

Working through a plugin, there were a couple of things I did not
know
how to do. Any pointers on best practices would be appreciated.
1) I would like to exposed operations based on the state (availability)
of the resource.
2) I would like to kick off discovery based on an operation being executed.
3) I would like to update availability based on an operation.
I assume some/all of this is supported.
