I have installed all-in-one using Kolla-ansible wallaby on a Virtual Machine (Debian 10) By default configurations up and running are able to create VMs .. with the default Cirros image. I want the Metering and Billing modules for a deployment scenario. So I used this setup as a PILOT and use ceilometer with cloudkitty and gnocchi.. I have enabled ( correct me If I am wrong or missing any other directives for metering and rating other than this if required => enable_ceilometer : "yes" enable_cloudkitty : "yes" enable_gnocchi : "yes" , enable_horizon_cloudkitty : "{{ enable_cloudkitty |bool }}" cloudkitty_collector_backend: "gnocchi" in /etc/kolla/globals.yml Then re deployed the all in one $ ( (venvopenstack) cloud@wallaby:~$ kolla-ansible -i ./all-in-one bootstrap-servers , (venvopenstack) cloud@Xena:~$ kolla-ansible -i ./all-in-one prechecks, (venvopenstack) cloud@Xena:~$ kolla-ansible -i ./all-in-one deploy ) .. All went well up and able to access horizon dashboard. How to view the metrics and ratings :: I am able to get Admin => Rating tab Enabled the three Rating Modules there. (Hashmap, noop, pyscripts) .. Rating Summary : I am getting as below All CloudTotal 0 LL <http://10.184.48.94/admin/rating_summary/ALL> Cloud Total <http://10.184.48.94/admin/rating_summary/ALL> 0 Hashmap and pyscrips tab nothing to view , its empty. How can I use this Rating module and how to get useful values there ? Or is there any other configurations I have to make to get a better metering and billing utility using these tools. Kindly share your tips and expertise with these tools. What / where to refer to get a nice Rating/metering configurations using these tools.( Or do I need to enable / configure more directives or resources ??) I have not seen a highly populated Rating Module interface in Horizon so it should be. Any reference images and configurations are most welcome. Thank you, Krish
