Hi, I've deployed Cloudkitty using Kolla-ansible, then I followed this example to test if the service is working : https://docs.openstack.org/cloudkitty/xena/user/rating/hashmap.html#examples I don't fully understand the service. I waited a day, and until now I don't have any results. The only errors I had is this once is : 2022-04-20 11:57:37.834 31 ERROR cloudkitty.orchestrator [-] [scope: a50e58ff494441b3b78ab096bca747d9, worker: 0 ] Error while collecting metric image.size at timestamp 2022-04-01 00:00:00+01:00: {'cause': "Metrics can't being aggregated", 'reason': 'Granularities are missing', 'detail': [['image.size', 'mean', 3600.0]]} (HTTP 400).

If so , how to correct it? i tried to create this file on my kolla-ansible deployer vim /etc/kolla/config/cloudkitty.conf [DEFAULT] debug = True [collect] metrics_conf = /etc/*cloudkitty-api*/metrics.yml (I don't know if this path is correct, since there is no /etc/cloudkitty on the nodes) And I created a directory like this : mkdir /etc/kolla/config/cloudkitty/ wget https://raw.githubusercontent.com/openstack/cloudkitty/master/etc/cloudkitty... -O /etc/kolla/config/cloudkitty/metrics.yml I executed then kolla-ansible -i multinode reconfigure -t cloudkitty All I have in the logs is : 2022-04-21 15:13:32.691 8 INFO cotyledon._service_manager [-] Child 1304 exited with status 1 2022-04-21 15:13:32.693 8 INFO cotyledon._service_manager [-] Child 1310 exited with status 1 2022-04-21 15:13:32.695 8 INFO cotyledon._service_manager [-] Child 1312 exited with status 1 2022-04-21 15:13:32.697 8 INFO cotyledon._service_manager [-] Child 1314 exited with status 1 2022-04-21 15:13:33.097 8 INFO cotyledon._service_manager [-] Child 1325 exited with status 1 2022-04-21 15:13:33.101 8 INFO cotyledon._service_manager [-] Child 1327 exited with status 1 2022-04-21 15:13:33.102 8 INFO cotyledon._service_manager [-] Forking too fast, sleeping 2022-04-21 15:13:38.109 8 INFO cotyledon._service_manager [-] Child 1329 exited with status 1 2022-04-21 15:13:38.112 8 INFO cotyledon._service_manager [-] Child 1331 exited with status 1 2022-04-21 15:13:38.114 8 INFO cotyledon._service_manager [-] Child 1333 exited with status 1 Any ideas?
