Hi,

I deployed Cloudkitty with the following metrics.yml file :

metrics:
cpu:
unit: instance
alt_name: instance
groupby:
- id
- user_id
- project_id
metadata:
- flavor_name
- flavor_id
- vcpus
mutate: NUMBOOL
extra_args:
aggregation_method: mean
resource_type: instance
force_granularity: 300

image.size:
unit: MiB
factor: 1/1048576
groupby:
- id
- user_id
- project_id
metadata:
- container_format
- disk_format
extra_args:
aggregation_method: mean
resource_type: image
force_granularity: 300

volume.size:
unit: GiB
groupby:
- id
- user_id
- project_id
metadata:
- volume_type
extra_args:
aggregation_method: mean
resource_type: volume
force_granularity: 300

I created a service for volume.size following the example here : https://docs.openstack.org/cloudkitty/yoga/user/rating/hashmap.html

I added the user cloudkitty to the admin project and to another project named Project01.

When showing the rates I have 0 rate on the Project01.

For example :

executing this command : openstack rating dataframes get | grep volume.size

This volume belongs to an instance in the Admin project, as you can see rating is 4.5:

| 2022-11-02T18:25:00 | 2022-11-02T18:30:00 | 31bfb5bcf7b7413da269d7a35a2fe69a | [{'rating': '4.5', 'service': 'volume.size', 'desc': {'volume_type': '246853e3-1215-4147-aef2-54012221ecc9', 'id': '07811807-474a-4eb5-91b5-ce2dcdd7be26', 'project_id': '31bfb5bcf7b7413da269d7a35a2fe69a', 'user_id': '2a3f2478e334473e85527102b76f7a2e'}, 'volume': '3.0', 'rate_value': '1.5000'}, {'rating': '4.5', 'service': 'volume.size', 'desc': {'volume_type': '246853e3-1215-4147-aef2-54012221ecc9', 'id': '8a345711-0486-4733-b8bc-fd1966678aec', 'project_id': '31bfb5bcf7b7413da269d7a35a2fe69a', 'user_id': '2a3f2478e334473e85527102b76f7a2e'}, 'volume': '3.0', 'rate_value': '1.5000'}, {'rating': '4.5', 'service': 'volume.size', 'desc': {'volume_type': '246853e3-1215-4147-aef2-54012221ecc9', 'id': 'afd22819-8faa-47ee-8c09-75290d2cf18e', 'project_id': '31bfb5bcf7b7413da269d7a35a2fe69a', 'user_id': '2a3f2478e334473e85527102b76f7a2e'}, 'volume': '3.0', 'rate_value': '1.5000'}]

This volume belongs to an instance in the Project01 project, as you can see rating is 0.0 :

| 2022-11-03T10:35:00 | 2022-11-03T10:40:00 | 2e80eb3b3d344ef9993065ce689395d9 | [{'rating': '0.0', 'service': 'volume.size', 'desc': {'volume_type': '246853e3-1215-4147-aef2-54012221ecc9', 'id': '1c396d46-8954-4e8c-b3e8-8e5e4eb6aba4', 'project_id': '2e80eb3b3d344ef9993065ce689395d9', 'user_id': 'd9e5696e99954ae1ac87db9cca82c839'}, 'volume': '20.0', 'rate_value': '0.0000'}]

I don't understand why it works for one and not the other?
