I installed Ceilometer+Gnocchi on my Pike/CentOS7 system, per instructions here:

https://docs.openstack.org/ceilometer...

After restarting Apache and logging in as admin, I don't have the Resource Usage option under Admin > System

The following services are up and running in the controller:

openstack-ceilometer-central.service
openstack-ceilometer-notification.service
openstack-gnocchi-api.service
openstack-gnocchi-metricd.service

Gnocchi shows up in the service list:

+----------------------------------+-----------+---------------------+
| ID                               | Name      | Type                |
+----------------------------------+-----------+---------------------+
| da73209b6c074c0f9350ad67223bcf18 | gnocchi   | metric              |
+----------------------------------+-----------+---------------------+

And the endpoints are in place:

+----------------------------------+-----------+--------------+---------------------+---------+-----------
| ID                               | Region    | Service Name | Service Type        | Enabled | Interface | URL                   
+----------------------------------+-----------+--------------+---------------------+---------+-----------
| 243fff6ad3d148ea885c2e60be7a0a3c | RegionOne | gnocchi      | metric              | True    | internal  | http://controller:8041                            
| abfff3e13d30462781b160814ec693ec | RegionOne | gnocchi      | metric              | True    | admin     | http://controller:8041                            
| d02ed9e967934f0b9a6f131823aac235 | RegionOne | gnocchi      | metric              | True    | public    | http://controller:8041

Am I missing something? What does Horizon Dashboard check for in order to display the resource usage option?
