Open Stack

Is Ceilometer ready for prime time?

I would be interested in hearing from people who have deployed OpenStack 
clouds with Ceilometer, and their experience. Some of the topics I am 
looking for feedback on are:

- Database Size
- MongoDB management, Sharding, replica sets etc.
- Replication strategies
- Database backup/restore
- Overall useability
- Gripes, pains and problems (things to look out for)
- Possible replacements for Ceilometer that you have used instead


If you are willing to share - I am sure it will be beneficial to the 
whole community.

Thanks in Advance
