[portstat, intfstat] update rates and utilization #817

mykolaf · 2020-02-21T08:48:43Z

According to HLD

- What I did
Update the logic for port rates and utilization
- How I did it

- How to verify it

- Previous command output (if the output of a command-line utility has changed)

admin@sonic:~$ show int count

what will be command to check RIF Counters ?
Has this been verified if RIF is both Over Port-Channel and VLAN ?

The command to check RIF counters is show interface counters rif .

+                                ns_diff(cntr.rx_drop, old_cntr.rx_drop),


Is the O/P of show interface counters remains same (backward compatible ) after these changes ? Is there any difference ?

There is no difference in how the output looks,
one difference in behavior is that clear command will not affect the rates&utilization. Still clears the counters.

I don't think these should be declared in this file. This needs to go inside portstat and rifstat respectively. This file is meant to be like a library for various formatting APIs

This assumes the port speed to be Gbps. Though most of the devices have lowest speed as 1 Gbps. I don't think it's a good design here. If SONiC is planned to be used for management and other low capacity devices in the future this will become a bug for ports less than 1Gbps. I would rather prefer logic using the port speed to determine the factor to divide rather than blindly assuming Gbps

Could you please describe the suggested approach in more detail?

I believe port speed can be used to figure out if it is in Gbps or Mbps. By default I believe speed is in Mbps (eg 40G is 40000)
