There is no documentation on any of this yet.

I guess you could go that way, my approach[1] is to observe the cookies directly (via syncrepl) where that of Howard's slapd-watcher[2] is to read the contextCSN from the DB/syncprov. As I usually mention in similar discussions, be wary of interpreting short-lived large differences between CSNs as long replication delays, you would emit many false positives.
