i assume you mean meter-list. it uses a combination of data from meter 
table and resource table[1]. this is because it lists all the meters and 
the resources associated with it. yes, it's complicated (which is why 
we'd recommend Gnocchi or your own special solution)

horizon uses ceilometerclient to grab data so i imagine they are using 
some combination of resource-list, sample-list, meter-list. as Matthias 
mentioned, you probably shouldn't rely on the existing horizon interface 
as the hope is to deprecate the view in horizon since no one is really 
sure what it's designed to show.

is this an addition to the work that Emma did[1]? i'm assuming so, given 
your locale/company.
