Hi Julien,

Thanks a lot for your answer.

How do you think, is it a right way to meter such data with ceilometer? I mean, such statistics should be transferred to collector each second, and in case of >1000 VM`s can easily bring down database. How do you think?

Anyway, what options I can have here, how do you think?

Thanks a lot,
NM

Unfortunately, the Ceilometer API doesn't allow to do that yet.  
You'll need to compute that on your own.

If you want to send samples through the API, this is the way:
