I may be wrong, but it seems like MongoDB is relevant only as a backend for Ceilometer. I'm also not sure if there are any configuration screens related to it.
To my current understanding: - In 4.x we used MySQL as backend for Ceilometer, due to know bugs of Ceilometer+MySQL Web GUI part of Ceilometer part didn't work - In 5.x we use MongoDB as backend for Ceilometer - all should be working neatly now :) --- Regards, Dmitriy On Sat, May 24, 2014 at 8:23 AM, Meg McRoberts <[email protected]>wrote: > Hi, all.
