[portstat, intfstat] update rates and utilization by mykolaf · Pull Request #817 · sonic-net/sonic-utilities

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)

sonic-utilities-tests/intfstat_test.py

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 .

abdosi · 2020-03-29T19:52:51Z

scripts/portstat

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 ratestat_dict is defined anywhere else in the file. Is there a missing piece of code?

 STATUS_NA = 'N/A'
 PORT_RATE = 40

+rates_key_list = [ 'RX_BPS', 'RX_PPS', 'RX_UTIL', 'TX_BPS', 'TX_PPS', 'TX_UTIL' ]


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

-        expected = ["Ethernet20        0  0.00 B/s    0.00/s         0        0  0.00 B/s    0.00/s         0",


Can you please include the new output in the test rather than just removing the expected here? I believe it's required to validate the output format

+        return STATUS_NA
+    else:
+        util = brate/(float(port_rate)*1024*1024*1024/8.0)*100


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)
