Description David Vallee Delisle 2017-12-14 14:17:39 UTC 
Description of problem:
We think it might be because each controller is overwriting the other controller's change.

We have a support exception for this setup with the customer.

Version-Release number of selected component (if applicable):
openstack-gnocchi-api-3.0.2-1

How reproducible:
All the time

Steps to Reproduce:
1. [storage]/driver = file on all 3 controllers
2. /var/lib/gnocchi points to same NFS share for all 3 controllers
3. wait

Actual results:
Missing metrics:

Expected results:
Have metrics on every 10 minutes

Additional info:
When we turn off ceilometer on 2/3 controllers, we get 100% of the metrics
