Stats Collection

We need to gather several stats in MongoDB or with ceilometer. Some of these will need to be exposed via the API, but the first step is recording, which is what this bp is all about.

Here are some possible metrics (starred items are most important).

Per account

Number of queues*
Total messages/day
Average messages/sec*

Per queue

Average messages/sec enqueued*
Number of messages*
Life of queue (how long since created)
Number of producers
Number of workers
Number of subscribers
Average message size
Average message TTL
Average message lifetime (explicitly deleted)
Average claim TTL
Average claim lifetime
Average number of messages posted per request
Average number of messages requested per GET or claim

Operations should be able to aggregate and graph these metrics across acounts.
