Before reporting an issue on Gnocchi, please be sure to provide all necessary
information.

Disclaimer: Idk is this the right place to ask the question. Hope it is.

cpu_util was computed wrongly and it makes Aodh alarms be wrong too.
Transformers and pipeline partitioning has been deprecated in Ceilometer, it means cpu_util will be unusable soon. In the commit message, @sileht wrote that "Also backend like Gnocchi offers a better alternative to compute them.". Is there any equivalent metric in Gnocchi? Or how to compute these metrics with Gnocchi? Do we have any documentations about this change?
If I have to compute metric using Gnocchi, how can I integrate with Aodh? Aodh just allows to get metric rather than compute it.

Thanks in advice.
