it looks like every notification is bound to the label: grep -A6 bandwidth meters.yaml - name: 'bandwidth' event_type: 'l3.meter' type: 'delta' unit: 'B' volume: $.payload.bytes project_id: $.payload.tenant_id resource_id: $.payload.label_id Wouldn't it make sense to change this to: - name: 'bandwidth' event_type: 'l3.meter' type: 'delta' unit: 'B' volume: $.payload.bytes project_id: $.payload.tenant_id resource_id: $.payload.label_id + "_" + $.payload.tenant_id Am 4/16/19 um 12:14 PM schrieb Florian Engelmann:

Hi,

I configured our neutron meters like:

labels: openstack network meter create --description "shared bandwidth-public-out" --share bandwidth-public-out openstack network meter create --description "shared bandwidth-public-in" --share bandwidth-public-in

rules: openstack network meter rule create --egress --remote-ip-prefix 0.0.0.0/0 bandwidth-public-out openstack network meter rule create --ingress --remote-ip-prefix 0.0.0.0/0 bandwidth-public-in

This created the iptables rules in all namespaces and collects data:

openstack metric measures show bc6c670f-cbb5-4fe1-974c-10455448fa27 +---------------------------+-------------+---------------+ | timestamp                 | granularity |         value | +---------------------------+-------------+---------------+ | 2019-04-15T16:00:00+02:00 |      3600.0 | 581854.954545 | | 2019-04-15T17:00:00+02:00 |      3600.0 | 23169398.5625 | | 2019-04-15T18:00:00+02:00 |      3600.0 |      586508.9 | | 2019-04-15T19:00:00+02:00 |      3600.0 | 1276372.84375 | | 2019-04-15T20:00:00+02:00 |      3600.0 | 507482.911765 | [...]

But how to know which project caused which amount of traffic?

It looks like only one metric is created for each label?

openstack metric list | grep bandwidth | 0f9f20a4-1c60-442f-81cb-48285e3f70da | ceilometer-ew-low | bandwidth                     | B       | efae8040-85d7-455a-958d-213a81ef98ef | | 1a058a79-965f-4a0a-a9ee-d482f57892ab | ceilometer-ew-low | bandwidth                     | B       | 837ed34a-65d2-42ef-924e-fd3c7e5aaed6 |

What does "shared" mean? I was not able to find any relevant documentation. Do I have to create a meter for each project or a rule or both? Is it possible to define a "default" meter and rule for every existing project and all future projects?

All the best, Flo
