Hi, Is there any way to extract timing metrics from the Nova, Neutron, Cinder, etc APIs? What I'm after is something similar to the Swift metrics reported via StatsD [1]. What's nice about StatsD is that you get useful timing data for each metric like min, max, avg, count, and 90th percentile. I'd like to get this same level of information from all the OpenStack APIs. When working on Java projects I've used Codahale Metrics [2] to get the same type of information. I know Ceilometer has some metric data but it's not down to the API level [3].
