[Bug 1623144] [NEW] Not collecting ceilometer volume data

[Jorge Niedbalski]

Public bug reported:

[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:
