Open Stack

Hi,

i have a question about alarms in openstack.

I want autoscaling with heat, and I'm looking for metric/alarm project
which I can use with heat.
I found that I can use Monasca or Ceilometer (with Aodh).
My question is:
Is any of you using heat (autoscaling) in production?
If yes what are you using (Monasca, Ceilometer, other) for metric and
alarms, and why?
