tripleo-gnocchi-ceilo-deployment

I validated the gnocchi integration end to end with ceilometer in tripleo:

1. file backend as default:

Connection to 192.0.2.17 closed.
Overcloud Endpoint: http://192.0.2.17:5000/v2.0
Overcloud Deployed

* On overcloud: Uploaded image to glance, and booted a nova vm to trigger metrics

* Check if metrics are propogated from ceilometer collector and flow into gnocchi:

* Note as of today the default archive policy needs to be created manually. But with this patch merged in gnocchi, we dont have to do that anymore:

https://review.openstack.org/#/c/290626/

Everything is functional from gnocchi POV.

2. Switched backend from file to swift/ceph (post deployment) and verified the same.

Originally we wanted swift to be the default backend. But as the gnocchi user/project is not created by keystone until the stack is created, deployment was failing. With file backend as default, all is well.

3. No upgrades needed as gnocchi is a new service.


Hope this helps with reviews.
