This reports whether this Correlation Unit currently has an active connection to its SmartEvent server, referred to as SEM, to forward correlated events upstream. Even if cpsead is reading logs fine locally, a broken connection here means correlated events pile up on the Correlation Unit without ever reaching the central SmartEvent console where analysts actually see them, a distinct failure mode from a log-reading problem. For example, this flipping to not connected during a network change between the Correlation Unit and SmartEvent server would explain a sudden gap in incidents appearing on the SmartEvent dashboard despite the Correlation Unit itself functioning.
