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 Danube +release, including new features, known issues and documentation updates. + +New features +============ + +For Danube release, the Doctor project focused primarily on enhancing the +testing tools, enabling additional test scenarios, and support and verification +on a wider range of OPNFV installers. + +* **Performance profiler PoC** + + The performance profiler is designed to get timestamp in each checkpoint of + components for further analysis. In Danube, initial PoC implementation of the + perfomance profiler has been added to the Doctor testing tools + by contribution from the `QTIP`_ team. The tools can now show how long it + takes for each component in a series of processes for fault notification. + Some checkpoints are not covered yet though. To activate this, set the + PROFILER_TYPE="poc" before running the main script ("tests/run.sh"). + See `DOCTOR-72`_ for more details. + +* **Testing with multiple tenant VMs** + + The Doctor testing tools now supports new testing scenario where multiple + tenant VMs in the system under test can be created (`DOCTOR-77`_). + This allows to measure fault notification time/cost with stressed VIM + controllers, in order to see perfomance trends. + +.. _QTIP: https://wiki.opnfv.org/display/qtip +.. _DOCTOR-72: https://jira.opnfv.org/browse/DOCTOR-72 +.. _DOCTOR-77: https://jira.opnfv.org/browse/DOCTOR-77 + +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 Danube release, key integrated feature is: + +* **Congress as Doctor Inspector** + + Congress Inspector is now verified with latest vanilla OpenStack without + backporting any patch, like the one we had backported for adding Doctor + driver of Congress in Colorado. + +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 Danube +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 | +| | | | Verified only | | +| | | | for admin users | | ++-----------+-------------------+--------------+-----------------+-------------------+ +| Fuel | Available | Available | Available, | N/A | +| | (`DOCTOR-58`_) | | Verified only | (`FUEL-230`_) | +| | | | for admin users | | ++-----------+-------------------+--------------+-----------------+-------------------+ +| Joid | Available | TBC | TBC | Available | +| | (`JOID-76`_), | | | (`JOID-73`_), | +| | Not verified | | | Not verified | ++-----------+-------------------+--------------+-----------------+-------------------+ +| Compass | Available | TBC | TBC | Available | +| | (`COMPASS-357`_), | | | (`COMPASS-367`_), | +| | Not verified | | | Not verified | ++-----------+-------------------+--------------+-----------------+-------------------+ + +.. _DOCTOR-58: https://jira.opnfv.org/browse/DOCTOR-58 +.. _FUEL-230: https://jira.opnfv.org/browse/FUEL-230 +.. _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 +===================== + +* **Configuration manual for Congress** + + Steps to configure Congress as Doctor Inspector have been added + to Doctor configuration manual (`DOCTOR-85`_). + +* **Alarm comparison** + + As part of the review between Doctor Danube (OpenStack Newton) and ETSI NFV + IFA, the alarm comparison table has been updated (`DOCTOR-82`_). + +* **OpenStack mechanisms for fencing** + + The section on fencing in the requirement document has been updated with more + details of Nova and Neutron (`REVIEW#27049`_). + +* **How to test** + + Two ways to run the Doctor testing tools have been added + (`REVIEW#28223`_). + +You can also find other minor updates in `DOCTOR-81`_. + +.. _DOCTOR-81: https://jira.opnfv.org/browse/DOCTOR-81 +.. _DOCTOR-82: https://jira.opnfv.org/browse/DOCTOR-82 +.. _DOCTOR-85: https://jira.opnfv.org/browse/DOCTOR-85 +.. _REVIEW#28223: https://gerrit.opnfv.org/gerrit/28223/ +.. _REVIEW#27049: https://gerrit.opnfv.org/gerrit/27049/ + +Known issues +============ + +* Doctor testing scenario is not verified with non-admin user (`DOCTOR-80`_). + +* Congress Nova driver is relying on deprecated Nova APIs and can lead to + an error (`BUG#1670345`_).
