Determine statistics reporting requirements for API-X

[birkland]

See comments on design doc draft

Regarding Service Discovery & Binding:

Such a management interface should provide an API for monitoring the running components and probably gather some metrics about things like request service time and failure conditions. For example via JMX or an HTTP API.

This issue is to determine if API-X needs to provide an interface for monitoring components and retrieving metrics, and what form that may take. Can any existing technologies and standards be leveraged for this?
