For DBAs and admins, 3.6 provides some new goodies. Ops Manager, the management pane for MongoDB, has borrowed some features already developed for Atlas (MongoDB's managed cloud service) and Compass, the visual DBA tool. There is the Data Explorer from Atlas that exposes the schema of the database. A new real-time performance advisor flags bottlenecks and makes indexing recommendations (and with a click, those new indexes can be autogenerated). Backups can now be queried; this feature will be useful if a replica has lost some data; rather than restore all of the backups, this new feature lets you query by point in time, and then restore selectively.
