There are currently 22 sections of the administrators guide. The organization of them does not flow well from one to the next. For example, Provisioning (Service Discovery/Management?) is section 9, while Service Assurance (Poller) is section 4, and Performance Management (Collectd) is section 5.
If a user was reading through the guide, it would make more sense to put service discovery before you talk about how to validate the service is running, or collect metrics from it.
