Open Stack

Hello everyone.
I'm having issues with the Neutron-Metering component inside
Kolla-Ansible, and I was hoping that you guys could help me :)
The problem is that Neutron Metering doesn't create/get the bandwidth metric.

I create a report of this inside the Neutron Launchpad, thinking that
maybe the Metering component had troubles:
https://bugs.launchpad.net/neutron/+bug/1945560

With the help of Bence, we've discovered that the messages of the
creation of metering labels and metering rules were OK inside
RabbitMQ.

After that, I deployed a new DevStack environment and, with the right
configuration, the Neutron Metering is working as it should, only
inside the DevStack environment.

That made me think that maybe Kolla Ansible had a flag to avoid the
modification of iptables and I found the flag
"docker_disable_default_iptables_rules" which I set to "no", as I'm
using the Wallaby version.
Setting this flag didn't do the trick and I was thinking that maybe
there is another flag or component of Kolla Ansible that prevents the
modification of iptables, apart from
"docker_disable_default_iptables_rules".

Thanks in advance.
Greetings!
