 * [Brent Ozar](https://www.brentozar.com/) for lots of (continuing) help on the SQL monitoring, with some of the initial queries and help letting us know many use cases to cover.  We'll be integrating some of the awesome tooling Brent and his team have to further assist DBAs and developers (like [sp_Blitz](https://www.brentozar.com/blitz/), [sp_BlitzIndex](https://www.brentozar.com/blitzindex/), and some you'll hear about soon).
