[openstack-dev] [Ceilometer] storage driver testing

Hello Sandy,

I'm very interested in performance results for Ceilometer. Now we have
successfully installed Ceilometer in the HA-lab with 200 computes and 3
controllers. Now it works pretty good with MySQL. Our next steps are:

1. Configure alarms
2. Try to use Rally for OpenStack performance with MySQL and MongoDB (
https://wiki.openstack.org/wiki/Rally)

We are open to any suggestions.

Thanks,
Nadya
