@judyjoseph please review. Was able to get a clean run after @jleveque fixed UT issues. |

Done. Will need approval again. |

@shyam77git, @Staphylo - do you approve? |
There was a problem hiding this comment.
We are in the process of migrating all Python code from Python 2 to Python 3. I would prefer if we start with this daemon as a Python 3-only daemon, rather than having to go back in the near future and convert it. If that is not possible, then we need to build and install both Python 2 and Python 3 versions of the daemon and use the new mechanism (in PR here) to assist with the transition.

Introducing chassisd process to monitor status of the control, line and fabric cards in a modular chassis.
The conf file will be present only in modular chassis SKUs

Introducing chassisd process to monitor status of the control, line and fabric cards in a modular chassis.
- Why I did it
Modular Chassis has control-cards, line-cards and fabric-cards along with other peripherals. Chassisd will be a central entity that has visibility of the entire chassis.
- How I did it
Chassisd process will monitor cards in the main thread. Another configuation_handling_task is created to listen to CONFIG_DB for admin_status up/down events.
The monitored status is persisted in REDIS-DB.
- How to verify it
Vendor will need to implement card.py. Template APIs are provided to monitor the status of the line-card, fabric-card etc using new PMON 2.0 APIs. The assumption is that each vendor will have platform-drivers or implementation to detect the status of the cards in the chassis.
