On an Observed object -- one managed object that UCS Manager's observe/monitoring framework is currently tracking and reporting changes for -- cucsObserveObservedGenNum is a Gauge32 counter/value representing the generation number UCS Manager increments each time this observed object's tracked data set changes. An admin monitors this number because it quantifies the internal progress or configuration of that specific Observed instance's operation, which is otherwise invisible outside UCS Manager's own FSM engine. For example, a rising or stalled value on cucsObserveObservedGenNum tells the admin whether the Observed instance's task is actively making progress or has stopped moving forward.
