Fix flex counters logic of converting poll interval to seconds from MS #878

noaOrMlnx · 2021-08-03T07:13:42Z

According to https://github.com/Azure/SONiC/blob/ec6d35dd2c28491bfade19cfee990fe612f1e5e9/doc/rates-and-utilization/Rates_and_utilization_HLD.md, counterpoll command gives polling interval in milliseconds.
So when converting them to seconds to be supplied to lua script this should be divide by 1000. However, syncd multiplies it by 1000.

Changed the multiplication to none, and did the converting in lua script - sonic-net/sonic-swss#1855
Fixed issue - sonic-net/sonic-buildimage#8392

syncd/FlexCounter.cpp

@@ -1597,7 +1597,7 @@ void FlexCounter::runPlugins(
    {
        std::to_string(counters_db.getDbId()),
        COUNTERS_TABLE,
-        std::to_string(m_pollInterval * 1000)
+        std::to_string(m_pollInterval / 1000)


m_pollInterval is set via orchagent with values in milliseconds (MS), currently this value was extended to microseconds, and now you changing this to seconds, so if m_pollInterval will be equal to let say 60ms or 100ms or 900ms, then your value in db will be set to zero (0) because of integer division, is that what you want ?

Done - removed the multiplication and did the required multiplication in the lua script - sonic-net/sonic-swss#1855

@kcudnik could you please help review?

i already posted my concerns in comment above, and still this is not addressed nor responded how this will be handled

@kcudnik Hi Kamil,
the request was addressed and the code has been changed.
appreciate if you'll take a look.
Thanks

i still don't see consistency here, what value is set in OA, what pooliterval value is stored in db and what value valie of pollinterval i passed to lua script

Hi Kamil. The value set in CLI is in milliseconds which is again set as milliseconds in orchagent. This value is again passed to lua script in milliseconds. So end to end we are using milliseconds. The lua scripts are updated to treat the input arg in milliseconds which is here sonic-net/sonic-swss#1855
Your initial concern was correct and we avoided converting milliseconds to seconds (since lua script expected seconds in arg). Now we have changed end to end and we do not convert anywhere and lua script rate calculation logic is updated considering poll interval as milliseconds.

thanks for deep answer on that, now i get the flow

The PR check "license/cla" seems have some issue. Could you commit an empty commit, to retrigger the check.
I checked https://cla.opensource.microsoft.com/Azure/sonic-sairedis?pullRequest=878, and it is not signed.
