Hi all,

I would like to know how the ceilometer calculate the value of each meter?
For example, the by using command “ceilometer sample-list -m cpu_util”, I can get the cpu_util values and timestamp values
Does this value means the cpu util. right on that timestamp, or the average value between last timestamp and this timestamp?

Thank you.
