Doctor platform components and features
=======================================
..
This section will be compiled into OPNFV composite document.
https://wiki.opnfv.org/doctor
Features
--------
Doctor platform, as of Brahmaputra release, provides the two features:
* Immediate Notification
* Consistent resource state awareness (Compute/host-down)
These features enable high availability of Network Services on top of
the virtualized infrastructure. Immediate notification allows VNF managers
(VNFM) to process recovery actions promptly once a failure has occurred.
Consistency of resource state is necessary to properly execute recovery
actions properly in the VIM.
Components
----------
Doctor platform, as of Brahmaputra release, consists of the following
components:
* OpenStack Compute (Nova)
* OpenStack Telemetry (Ceilometer)
* OpenStack Alarming (Aodh)
* Doctor Inspector
* Doctor Monitor
.. note::
Doctor Inspector and Monitor are sample implementation for reference.
