You could build your own using Domo. There are datasets called 'Domostats' (I think you have to call support and have them enable them in your instance, I can't remember offhand) which show metadata about your instance. There is one called 'Domo Dataflow' which has metadata about your dataflows, one attribute of which is the 'last modified date', so you could build a dataflow that flags when the last modified date = today (or whatever your logic may be), build a card that only shows those records, and then fires an alert to you anytime the number increases by 1 (or otherwise changes).
