data store
Storage system for recording data collected by ceilometer.
meter
The measurements tracked for a resource. For example, an instance has
a number of meters, such as duration of instance, CPU time used,
number of disk io requests, etc.
Three types of meters are defined in ceilometer:
* Cumulative: Increasing over time (e.g. disk I/O)
* Gauge: Discrete items (e.g. floating IPs, image uploads) and fluctuating
values (e.g. number of Swift objects)
* Delta: Incremental change to a counter over time (e.g. bandwidth delta)
