With replication being such a core aspect of the IBM Notes and Domino platform, it's surprising that the native tools don't make it easier for you to get a handle on the "big picture." Workflow is limited to cross-checking between static lists and dialog boxes.
replicationEZ is a game changer, letting you see a global replication snapshot—including a graphical chart of your replication topology, and up to 80 different properties—across multiple servers all at once. Approach your analyses from the angle that best suits your task: zoom in on any problems from the larger context, or perform a forensic analysis directly concentrating on a suspected problem database.
