[32645] Missing measurements in Gnocchi on environments with Barbican¶

^{Pike, Queens}

Fixed the issue with Gnocchi failing to collect some metrics from other OpenStack services if Barbican listens to the same notification topic as Ceilometer does. The issue affected only the OpenStack environments with Barbican enabled.

To apply the issue resolution:

1. Log in to the Salt Master node.

2. Create a separate topic for Barbican to listen to Keystone messages:

   1. In classes/cluster/<cluster_name>/openstack/init.yml, add the keystone_notification_topics parameter right after openstack_notification_topics:

      parameters:
        _param:
        ...
        openstack_notification_topics: <some_value>
        keystone_notification_topics: "${_param:openstack_notification_topics},barbican"
      

   2. In classes/cluster/<cluster_name>/openstack/barbican.yml, add the ks_notifications_topic parameter:

      parameters:
          barbican:
            server:
              ...
              ks_notifications_topic: barbican
      

3. Refresh pillars on the Keystone and Barbican nodes and apply the changes:

   salt -C 'I@keystone:server' saltutil.refresh_pillar
   salt -C 'I@barbican:server' saltutil.refresh_pillar
   salt -C 'I@keystone:server:role:primary' state.apply keystone.server
   salt -C 'I@keystone:server' state.apply keystone.server
   salt -C 'I@barbican:server:role:primary' state.apply barbican.server
   salt -C 'I@barbican:server' state.apply barbican.server
