-Platform overview
-"""""""""""""""""
-
-Doctor platform provides these features in `Danube Release <https://wiki.opnfv.org/display/SWREL/Danube>`_:
-
-* Immediate Notification
-* Consistent resource state awareness for compute host down
-* Valid compute host status given to VM owner
-
-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 execute recovery actions
-properly in the VIM.
-
-Ability to query host status gives VM owner the possibility to get
-consistent state information through an API in case of a compute host
-fault.
-
-The Doctor platform 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 implementations for reference.
-
-You can see an overview of the Doctor platform and how components interact in
-:numref:`figure-p1`.

-
-Use case
-""""""""
-
-* A consumer of the NFVI wants to receive immediate notifications about faults
- in the NFVI affecting the proper functioning of the virtual resources.
- Therefore, such faults have to be detected as quickly as possible, and, when
- a critical error is observed, the affected consumer is immediately informed
- about the fault and can switch over to the STBY configuration.
-
-The faults to be monitored (and at which detection rate) will be configured by
-the consumer. Once a fault is detected, the Inspector in the Doctor
-architecture will check the resource map maintained by the Controller, to find
-out which virtual resources are affected and then update the resources state.
-The Notifier will receive the failure event requests sent from the Controller,
-and notify the consumer(s) of the affected resources according to the alarm
-configuration.
-
-Detailed workflow information is as follows:
-
-* Consumer(VNFM): (step 0) creates resources (network, server/instance) and an
- event alarm on state down notification of that server/instance
-
-* Monitor: (step 1) periodically checks nodes, such as ping from/to each
- dplane nic to/from gw of node, (step 2) once it fails to send out event
- with "raw" fault event information to Inspector
-
-* Inspector: when it receives an event, it will (step 3) mark the host down
- ("mark-host-down"), (step 4) map the PM to VM, and change the VM status to
- down
-
-* Controller: (step 5) sends out instance update event to Ceilometer
-
-* Notifier: (step 6) Ceilometer transforms and passes the event to Aodh,
- (step 7) Aodh will evaluate event with the registered alarm definitions,
- then (step 8) it will fire the alarm to the "consumer" who owns the
- instance
-
-* Consumer(VNFM): (step 9) receives the event and (step 10) recreates a new
- instance
-
-Test case
-"""""""""
-
-Functest will call the "run.sh" script in Doctor to run the test job.
-
-Currently, only 'Apex' and 'local' installer are supported. The test also
-can run successfully in 'fuel' installer with the modification of some
-configurations of OpenStack in the script. But still need 'fuel' installer
-to support these configurations.
-
-The "run.sh" script will execute the following steps.
-
-Firstly, get the installer ip according to the installer type. Then ssh to
-the installer node to get the private key for accessing to the cloud. As
-'fuel' installer, ssh to the controller node to modify nova and ceilometer
-configurations.
-
-Secondly, prepare image for booting VM, then create a test project and test
-user (both default to doctor) for the Doctor tests.
-
-Thirdly, boot a VM under the doctor project and check the VM status to verify
-that the VM is launched completely. Then get the compute host info where the VM
-is launched to verify connectivity to the target compute host. Get the consumer
-ip according to the route to compute ip and create an alarm event in Ceilometer
-using the consumer ip.
-
-Fourthly, the Doctor components are started, and, based on the above preparation,
-a failure is injected to the system, i.e. the network of compute host is
-disabled for 3 minutes. To ensure the host is down, the status of the host
-will be checked.
-
-Finally, the notification time, i.e. the time between the execution of step 2
-(Monitor detects failure) and step 9 (Consumer receives failure notification)
-is calculated.
-
-According to the Doctor requirements, the Doctor test is successful if the
-notification time is below 1 second.
