Subject Re: Strategies for managing and monitoring large Qpid topologies in mission critical systems
Date Thu, 22 Sep 2011 18:01:45 GMT
Hi David,
I think it's only the Java broker that exposes JMX attributes at the 

When I (eventually - hopefully next couple of weeks if I don't get 
distracted!!) get the Java QMF2 API done I'm hoping that'll be a good 
starting point for exposing QMF2 Management Objects as MBeans.

I believe that there is something called QMan mentioned in the Wiki that 
"is a tool that dynamically reads the QMF Schema information and creates 
JMX objects that consumed by any JMX console or application server to 
manage Qpid". I never got very far with that nor with the Java QMF1 
Console, which appeared fairly broken when I tried it - certainly with 
respect to the C++ broker (a lot of the brokenness was actually my old 
friend byte[] where String was expected :-)) so I gave up on that and 
started down the QMF2 path.

On the general topic of Management I was only really using OpenView as 
an example - I remain really interested in what people are using in 
practice to manage and monitor their broker networks. I'm looking into 
Cumin which looks quite nice. Does anyone know of nice eye-candy for 
visualising federated broker topologies - or am I going to have to write 
one :-)
