you see them in sample-list and not meter-list? if that's the case, it's 
probably because the api doesn't return full dataset. i believe it's 
limited to 100 or a 1000.

regardless, i'm going to add obligatory ceilometer storage is 
unsupported and deprecated. use Gnocchi[1] or another time-series 
optimised solution. you're going to run into massive scaling issues 
(each datapoint in mongodb driver is over >1KB), especially if you're 
collecting collectd stats.
