>
> Had the following idea:
> What if there was an event interface that could be implemented by various 
> services, whose job was to "report status"; things like pool sizes, loaded 
> pages, components, etc.  
> Lets call the event interface MonitorListener
> public void monitorStatusRequested(MonitorEvent event);
> Service implementations could register with the service (say 
> tapestry.monitor.MonitorEventCoordinator).
> A page or component could uses the coordinator service to query the services 
> of Tapestry and format it into an HTML report.  Leverage the 
> DescriptionReceiver interface (the event could implement the interface, or 
> provide a receiver object that does).  The "Engine" tab of the Inspector 
> could make use of this as well.
> This would be a great way to gain some introspection into the underlying 
> status of Tapestry without cluttering up all the service interfaces.
