After those features were implemented, OPNFV installer +projects integrated the features to the OPNFV platform and the OPNFV +infra/testing projects verified the functionalities in the OPNFV Labs. + +This document provides an overview of the Doctor project in the OPNFV Colorado +release, including new features, known issues and documentation updates. + +New features +============ + +* **Congress as a Doctor Inspector** + + Since `Doctor driver`_ in OpenStack Congress has been implemented in Mitaka, + OpenStack Congress can now take the role of the Doctor Inspector to correlate + an error in a physical resource to the affected virtual resource(s) + immediately. + +.. _Doctor driver: https://review.openstack.org/#/c/314915/ + +Installer support and verification status +========================================= + +Integrated features +------------------- + +Minimal Doctor functionality of VIM is available in the OPNFV platform from +the Brahmaputra release. The basic Doctor framework in VIM consists of a +Controller (Nova) and a Notifier (Ceilometer+Aodh) along with a sample +Inspector and Monitor developed by the Doctor team. +From the Colorado release, key integrated features are: + +* Immediate notification upon state update of virtual resource enabled by + Ceilometer and Aodh (Aodh integration) + +* Consistent state awareness improved by having nova API to mark nova-compute + service down (Nova: Force compute down) + +* Consistent state awareness improved by exposing host status in server (VM) + information via Nova API (Nova: Get valid service status) + +* OpenStack Congress enabling policy-based flexible failure correlation + (Congress integration) + +OPNFV installer support matrix +------------------------------ + +In the Brahmaputra release, only one installer (Apex) supported the deployment +of the basic doctor framework by configuring Doctor features. In the Colorado +release, integration of Doctor features progressed in other OPNFV installers. + ++-----------+-------------------+--------------+-----------------+------------------+ +| Installer | Aodh | Nova: Force | Nova: Get valid | Congress | +| | integration | compute down | service status | integration | ++===========+===================+==============+=================+==================+ +| Apex | Available | Available | Available | Available | +| | | | (`DOCTOR-67`_), | (`APEX-135`_, | +| | | | Verified only | `APEX-158`_), | +| | | | for admin users | Not Verified | ++-----------+-------------------+--------------+-----------------+------------------+ +| Fuel | Available | Available | Available, | N/A | +| | (`DOCTOR-58`_), | | Verified only | (`FUEL-119`_) | +| | Not verified | | for admin users | | ++-----------+-------------------+--------------+-----------------+------------------+ +| Joid | Available | TBC | TBC | TBC | +| | (`JOID-76`_), | | | (`JOID-73`_) | +| | Not verified | | | | ++-----------+-------------------+--------------+-----------------+------------------+ +| Compass | Available | TBC | TBC | N/A | +| | (`COMPASS-357`_), | | | (`COMPASS-367`_) | +| | Not verified | | | | ++-----------+-------------------+--------------+-----------------+------------------+ + +.. _DOCTOR-67: https://jira.opnfv.org/browse/DOCTOR-67 +.. _APEX-135: https://jira.opnfv.org/browse/APEX-135 +.. _APEX-158: https://jira.opnfv.org/browse/APEX-158 +.. _DOCTOR-58: https://jira.opnfv.org/browse/DOCTOR-58 +.. _FUEL-119: https://jira.opnfv.org/browse/FUEL-119 +.. _JOID-76: https://jira.opnfv.org/browse/JOID-76 +.. _JOID-73: https://jira.opnfv.org/browse/JOID-73 +.. _COMPASS-357: https://jira.opnfv.org/browse/COMPASS-357 +.. _COMPASS-367: https://jira.opnfv.org/browse/COMPASS-367 + +Note: 'Not verified' means that we didn't verify the functionality by having +our own test scenario running in OPNFV CI pipeline yet. + +Documentation updates +===================== + +* **Alarm comparison** + + A report on the gap analysis across alarm specifications in ETSI NFV IFA, + OPNFV Doctor and OpenStack Aodh has been added, along with some proposals + on how to improve the alignment between SDO specification and OSS + implementation as a future work (`DOCTOR-46`_). + +.. _DOCTOR-46: https://jira.opnfv.org/browse/DOCTOR-46 + +* **Description of test scenario** + + The description of the Doctor scenario, which is running as one of the + feature verification scenarios in Functest, has been updated (`DOCTOR-53`_). + +.. _DOCTOR-53: https://jira.opnfv.org/browse/DOCTOR-53 + +* **Neutron port status update** + + Design documentation for port status update has been added, intending to + propose new features to OpenStack Neutron. + +* **SB I/F specification** + + The initial specification of the Doctor southbound interface, which is for + the Inspector to receive event messages from Monitors, has been added + (`DOCTOR-17`_). + +.. _DOCTOR-17: https://jira.opnfv.org/browse/DOCTOR-17 + +Known issues +============ + +* **Aodh 'event-alarm' is not available as default (Fuel)** + + In Fuel 9.0, Aodh integration for 'event-alarm' is not completed. + Ceilometer and Nova would be mis-configured and cannot pass event + notification to Aodh. + You can use `fuel-plugin-doctor`_ to correct Ceilometer and Nova + configuration as a workaround.
