  | From the user's perspective Actions are not unique since they can be reused from service to service by wiring in via the jboss-esb.xml.

Yes, but within a deployment, the combination of esb instance, service name, action name and action instance name will be unique.

That's definitely a service, but our services model is based on action chaining. Which is why I think TomC was interested in also monitoring and reporting on Actions. Developers do see Actions ;-)

That's services, but as a user with services that have N actions, I'd like to have information on those individual actions. Finer grained.

Agreed.

It's a service that contains Actions that we may like to see reports on.
