Cool. In that case, here is the script we've been running for years to check that our 4 MMR servers are synced. It occasionally blips when we do a major idm run that creates or deletes 20-30 thousand accounts, but other than that I rarely if ever get alerts from it. It runs on each of the four servers, and our config management server populates it with the names of the other three to check.
