Bug Description

In ceilometer we transform all notifications from nova with event type 'compute.instance.*' to samples with counter_name 'instance'. So, one instance running creates 8 notifications compute.instance.update, which are collected as 'instance' sample.
This behavior generates redundant samples and hinders get valid statistics for this meter.
I think we should to separate compute.instance.* to several different meters.

Isn't notify_on_state_change in nova.conf used to control the notifications behavior here?

Ilya, is there any chance for changing the behavior soon? Was there a discussion about possible timeline?
