hi Ignazio, Mongo doesn't require you to explicitly create the Ceilometer collection. the step in the documentation is more to create a user with appropriate credentials to write to the Ceilometer collection. if you define your metering_connection appropriately ie 'mongodb://ceilometer:CEILOMETER_DBPASS@controller:27017/ceilometer' it will write to the data to ceilometer collection. i should also mention that there is a sql backend if you are more familiar with PostgreSQL/MySQL. depending on your use case, it may be an alternative as using PostgreSQL has been found to be significantly more efficient from disk usage pov versus MongoDB. MongoDB requires significant experience and hardware to scale appropriately.
