Title:
  Not collecting ceilometer volume data

Status in cinder package in Juju Charms Collection:
  Fix Released

Bug description:
  [Environment]

  Trusty-Mitaka
  Charms 16.07

  [Description]

  Some installations require to gather usage metrics from volumes.

  By default those metrics are not enabled:

  buntu at niedbalski-sec-bastion:~/openstack-charm-testing$ curl -H X-Auth-Token:$TOKEN http://$CEILOMETER:8777/v2/meters | python -m json.tool|grep -i vol
    % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed
  100  2902  100  2902    0     0   133k      0 --:--:-- --:--:-- --:--:--  134k

  
  In order to enable this, it is required to set some configuration variables in cinder.conf

  control_exchange = cinder 
  volume_usage_audit_period = hour 

  AND enable the messaging version 2 notifications:

  [oslo_messaging_notifications]
  driver = messagingv2

  Also, it is required to set a recurring cronjob for gathering the
  data:

  0 * * * * (PYTHONIOENCODING=utf-8 /usr/bin/cinder-volume-usage-audit
  1>> /var/log/cinder/cinder_audit_hourly_`date +\%Y\%m\%d`.log 2>&1)

  After enabling these configuration directives:

  ubuntu at niedbalski-sec-bastion:~/openstack-charm-testing$ curl -H X-Auth-Token:$TOKEN http://$CEILOMETER:8777/v2/meters | python -m json.tool| grep vol                                                                                 
    % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed
  100  8582  100  8582    0     0  38184      0 --:--:-- --:--:-- --:--:-- 38312
