A simple way to do is to measure dataset size of source DC and new DC (one you are rebuilding) every hour or so and make sure new DC dataset size is catching up. Not a very effective but helps me. We recently rebuilt a DC and watched that way. Another idea is to poll system.log for errors related with stream and send notification to yourself. Sincerely,

While it's building, it will also show you the active streams that are in progress. Typically, most admins nohup it or at least redirect the output to a log file so you still have visibility when you lost your [SSH] session. That's also another thing to consider. Cheers!
