Currently we have alerting for replication lag that leads to a PROACTIVE ticket (e.g. https://jira.mongodb.org/browse/PROACTIVE-118019). The threshold for this is currently multiple days, which is at least an order of magnitude over our target for maximum replication lag and is far too long to catch problems before customers notice. We should determine what the lowest reasonable time for this is and reduce the alerting threshold to that.
