[Bug 1837861] Re: Shared Neutron Meter Label not processed correctly

[Merlin]

As a workaround create a meter label for every project itself:

import openstack
conn = openstack.connect(cloud='test')

def createBillingMeteringLabel(projectId):
    '''Creates Billing Label for internet exgress traffic for a project'''
    label = conn.network.create_metering_label(
            name='billing-exgres', project_id=projectId)
    conn.network.create_metering_label_rule(
        direction='egress',
        metering_label_id=label.id, project_id=projectId,
        remote_ip_prefix='0.0.0.0/0')
    privateCidrs = ['10.0.0.0/8', '172.16.0.0/12', '192.168.0.0/16']
    for privateNet in privateCidrs:
        conn.network.create_metering_label_rule(
            direction='egress', is_excluded=True,
            metering_label_id=label.id, project_id=projectId,
            remote_ip_prefix=privateNet)

Title:
  Shared Neutron Meter Label not processed correctly

Status in ceilometer package in Ubuntu:
  New

Bug description:
  # Description
  Shard neutron meter label don't create bandwidth meters in gnocchi.
  The meter label is only attached to one extra project.

  # Expected behavior
  Shared Meter label should be processed for every project containing the project_id of the project that the measures are linked to.

  #Reproduce
  1. Create Multiple Projects
  2. Create a shared metering label for the admin project:
  openstack network meter create billing-exgress-public --description "Meter for billing only exgress traffic to the internet" --share
  while read line; do openstack network meter rule create --egress --exclude  --remote-ip-prefix "$line" billing-exgress-public  ; done <cidr-private.txt
  openstack network meter rule create --egress --include  --remote-ip-prefix 0.0.0.0/0 billing-exgress-public
  3. Check the Gnoochi Database for network resources
  gnocchi resource list -f json | grep -C 5 'network"'
  gnocchi measures aggregation -m bandwidth --aggregation mean  --query "project_id=<ProjectID>" --resource-type network --needed-overlap 0 --groupby original_resource_id --utc  --granularity 300 --fill 0"
