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`. - -.. figure:: ./images/figure-p1.png - :name: figure-p1 - :width: 100% - - Doctor platform and typical sequence - -Detailed information on the Doctor architecture can be found in the Doctor -requirements documentation: -http://artifacts.opnfv.org/doctor/docs/requirements/05-implementation.html - -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. diff --git a/docs/scenarios/functest/images/LICENSE b/docs/scenarios/functest/images/LICENSE deleted file mode 100644 index f2b47d20..00000000 --- a/docs/scenarios/functest/images/LICENSE +++ /dev/null @@ -1,14 +0,0 @@ -Copyright 2015 Open Platform for NFV Project, Inc. and its contributors - -Open Platform for NFV Project Documentation License -=================================================== -Any documentation developed by the "Open Platform for NFV Project" -is licensed under a Creative Commons Attribution 4.0 International License. -You should have received a copy of the license along with this.
