Hi,

How to set up aodh and heat to auto scale in openstack victoria based on cpu usage?

As the metric cpu_util is now deprecated, how can someone use heat to auto scale up and down using cpu usage of the instance?

I checked the ceilometer package and I could see the transformers are removed so i can't see any other way to perform arithmetic operations and generate cpu usage in percentage. 

Any insight is appreciated.

with regards
