Enable show interfacess counters on chassis supervisor (sonic-net#3488)
Browse files Browse the repository at this point in the history 
What I did
I modify the portstat script and the implementation of Class Porstat to enable the Chassis Supervisor to collect port counters from linecards. By doing so, "show interfaces counters" on the Chassis Supervisor can now collect port counters from linecards and display them on the CLI.

How I did it
I made the Class Portstat aware of chassis environment and added logic to collect port counters from linecards through "GET_LINECARD_COUNTER|pull" signal in CHASSIS_STATE_DB. And I also added an agent on every linecard to collect port counters and send them to CHASSIS_STATE_DB on the Chassis Supervisor.

Note: the agent is not part of this PR. The current agent used in my test is only for internal use in MSFT.

How to verify it
Run it on a SONiC Chassis Supervisor and make sure the Linecards are equipped with agents to publish port counters to CHASSIS_STATE_DB.
