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
LLCloud Total0

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,
