4 Doctor platform components and features
5 =======================================
8 This section will be compiled into OPNFV composite document.

15 Doctor platform provides these features in `Colorado Release <https://wiki.opnfv.org/display/SWREL/Colorado>`_:
17 * Immediate Notification
18 * Consistent resource state awareness for compute host down
19 * Valid compute host status given to VM owner
21 These features enable high availability of Network Services on top of
22 the virtualized infrastructure.
24 Immediate notification allows VNF managers (VNFM) to process recovery
25 actions promptly once a failure has occurred.
27 Consistency of resource state is necessary to properly execute recovery
28 actions properly in the VIM.
30 Ability to query host status gives VM owner (VNFM) the possibility to get
31 consistent state information through an API in case of a compute host
37 Doctor platform, as of Colorado release, consists of the following
40 * OpenStack Compute (Nova)
41 * OpenStack Telemetry (Ceilometer)
42 * OpenStack Alarming (Aodh)
47 Doctor Inspector and Monitor are sample implementation for reference.
