Ceilometer doesnt get "bandwidth" metric

[Uriel Medina]

Hello everyone!
I'm trying to get the "bandwidth" metric from all of the instances.
I've already installed the neutron-metering agent using Kolla-Ansible.
Also, I've created two meters for neutron:
+--------------------------------------+-----------+-------------+--------+
| ID | Name | Description | Shared |
+--------------------------------------+-----------+-------------+--------+
| 64d3ca0d-30c3-4159-8a8c-c011e54be83a | name1-out | | |
| 6927ce7d-413c-4749-9e74-6725c59c2de2 | name1-in | | |
+--------------------------------------+-----------+-------------+--------+

I've already also created the rules for the ingress and egress:
+--------------------------------------+----------+-----------+------------------+------------------+-----------------------+
| ID | Excluded | Direction | Remote IP Prefix | Source IP Prefix | Destination IP Prefix |
+--------------------------------------+----------+-----------+------------------+------------------+-----------------------+
| 0f11b59d-3e94-4886-a30f-348ce9cacfa7 | | ingress | 192.168.0.0/24 | None | None |
| 7f88e16f-a58c-42c8-9447-82843a41591e | | egress | 192.168.0.0/24 | None | None |
+--------------------------------------+----------+-----------+------------------+------------------+-----------------------+

And this is the detail of one of my VMs, where I want to measure the bandwidth:
+-------------------------------------+----------------------------------------------------------+

As far as I can see, everything else is well configured.
I took a look at ceilometer measurements and saw that this metric "bandwidth" needed a "notification" origin, which make me wonder If I had ceilometer configured well to get this metric.

The trouble is that I have 3 docker containers: ceilometer-compute, ceilometer-central and ceilometer-notification.
By default, Kolla-Ansible deploys ceilometer based on events (I think), but only in the ceilometer-notification container I have two differents files, which are:
*event_definitons.yaml
*event_pipeline.yaml

The content of event_definitions.yaml is the same found in the repo:
https://github.com/openstack/ceilometer/blob/master/ceilometer/pipeline/data/event_definitions.yaml

And the content of event_pipeline.yaml is this:
---
sources:
    - name: event_source
      events:
          - "*"
      sinks:
          - event_sink
sinks:
    - name: event_sink
      publishers:
          - gnocchi://

Also, I have 2 polling files:
*polling_all.yaml
*polling.yaml

The content of polling_all.yaml is:
---
sources:
    - name: all_pollsters
      interval: 300
      meters:
        - "*"

And the content of polling.yaml is:
---
sources:
    - name: some_pollsters
      interval: 300
      meters:
        - cpu
        - cpu_l3_cache
        - memory.usage
        - network.incoming.bytes
        - network.incoming.packets
        - network.outgoing.bytes
        - network.outgoing.packets
        - disk.device.read.bytes
        - disk.device.read.requests
        - disk.device.write.bytes
        - disk.device.write.requests
        - hardware.cpu.util
        - hardware.cpu.user
        - hardware.cpu.nice
        - hardware.cpu.system
        - hardware.cpu.idle
        - hardware.cpu.wait
        - hardware.cpu.kernel
        - hardware.cpu.interrupt
        - hardware.memory.used
        - hardware.memory.total
        - hardware.memory.buffer
        - hardware.memory.cached
        - hardware.memory.swap.avail
        - hardware.memory.swap.total
        - hardware.system_stats.io.outgoing.blocks
        - hardware.system_stats.io.incoming.blocks
        - hardware.network.ip.incoming.datagrams
        - hardware.network.ip.outgoing.datagrams

When I try to get the metric with "openstack metric list | grep bandwidth", nothing shows up.

The neutron-metering log shows effectively how nothing is getting found:
2021-09-29 23:36:31.409 7 DEBUG neutron.services.metering.agents.metering_agent [-] Traffic counters [{}] retrieved for routers [{'52100624-471d-4e7e-a19f-ff87e8161070': {'id': '52100624-471d-4e7e-a19f-ff87e8161070', 'name': 'demo-router', 'tenant_id': '8c9e007415c745feb315a11e7f410c0d', 'admin_state_up': True, 'status': 'ACTIVE', 'gw_port_id': '83161bcf-46ca-4b1d-931f-8794a5a5c9e9', 'distributed': False, '_metering_labels': [{'id': '64d3ca0d-30c3-4159-8a8c-c011e54be83a', 'rules': [{'id': '7f88e16f-a58c-42c8-9447-82843a41591e', 'metering_label_id': '64d3ca0d-30c3-4159-8a8c-c011e54be83a', 'direction': 'egress', 'remote_ip_prefix': '192.168.0.0/24', 'source_ip_prefix': None, 'destination_ip_prefix': None, 'excluded': True}], 'shared': True, 'name': 'name1-out'}, {'id': '6927ce7d-413c-4749-9e74-6725c59c2de2', 'rules': [{'id': '0f11b59d-3e94-4886-a30f-348ce9cacfa7', 'metering_label_id': '6927ce7d-413c-4749-9e74-6725c59c2de2', 'direction': 'ingress', 'remote_ip_prefix': '192.168.0.0/24', 'source_ip_prefix': None, 'destination_ip_prefix': None, 'excluded': True}], 'shared': True, 'name': 'name1-in'}]}}]. _add_metering_infos /var/lib/kolla/venv/lib/python3.6/site-packages/neutron/services/metering/agents/metering_agent.py:224

I'll appreciate any help.
Thanks and Greetings!

hi，Uriel Medina
have you solved this problem？ I encountered the same problem, Can you give me some advice?
