Found inconsistency of SXL instances between SGMs

Hi guys!

It looks like asg perf has found some inconsistencies in SLX instances. Here's the output:

* Core usage shows avg, min, or max, as sampled during last 10 seconds

 

We made sure that fwaffinity.conf file has "i default auto" on both SGMs (nobody has ever meddled with that setting anyway).

Where does it find those 'inconsistencies' in that setup?

 

Cheers!

If dynamic balancing is enabled (default in R81.20+) then this is expected behaviour.

So it finds discrepancies between SXL instances because the core affinities are dynamically changed depending on the characteristics of the traffic. Do I get this correctly?

Yes, that's correct.

starting from the JHF98, this information disappeared from the output:

The information about cores in the “asg perf” output is only get from the local SGM. Accordingly, warnings about mismatches with other SGMs simply cannot occur
