monitoring open http sessions on a jboss server
by Attila Heidrich
Hi,
is there a way to monitor the open sessions of a jboss server?
I see I have some metrics for the http connector, and the requests per
second value is really useful, but we need some more detailed statistics.
It would be the best to have some browser to select the parameters... ;)
for webapp dveelopers it would be such a great benefit!
Afaik, there're some internal values in the jboss server, should I extend
the JBoss plugin to get a value, which isn't got now?

F5 GTM - RHQ Agent configuration issue
by barry.barnett@wellsfargo.com
We currently have the following configuration for our RHQ server:
Production RHQ Server 1 (Node A)
Production RHQ Server 2 (Node B)
* Both nodes connected to the Oracle backend database)
* Storage nodes on each instance, clustered
BCP RHQ Server (Node C - different location)
* Storage node not in cluster
We have an F5 URL that sits infront of all the nodes, and can point to any of them in the following scenario:
* Prod Node A fails, traffic directed to Prod Node B
* Prod Node A and B fails, traffic directed to BCP Node C
When an RHQ agent on a client windows box is configured, and the F5 GTM URL is used as the RHQ Server, the agent connects to Prod Node A (as that node is the primary active node for the F5 to point to). If I bring down both Prod Nodes, I would think the F5 URL would connect the agent to the BCP Node C RHQ server. But, it never connects to BCP, but rather in its logs shows it trying to connect to both Prod nodes and failing. Is this due to the storage nodes in Prod being clustered (assumption)? Why wouldn't the F5 URL direct the agent to connect to BCP?
