you can consider ceilometer database (and api) as an open-ended model designed to capture the full fidelity of a datapoint (something useful for auditing, post processing). alternatively, gnocchi is a strongly type model which captures only required data.
in the case of ceilometer -> gnocchi, the measurement data ceilometer collects is sent to gnocchi and mapped to specific resource types[1]. here we define all the resources and the metric mappings available. with regards to collectd, i'm just wondering what additional metrics are added and possibly any interesting metadata?
