dpdkvifstats.py script issue #23

Closed pinggit closed 3 years ago

pinggit commented 3 years ago

this does not looks correct: image

currently I have only 2 fwding cores:

[root@a7s3 ~]# taskset -cap `pidof contrail-vrouter-dpdk`
pid 3701's current affinity list: 5,11
pid 3751's current affinity list: 5,11
pid 3752's current affinity list: 5,11
pid 3778's current affinity list: 5,11
pid 3779's current affinity list: 5,11
pid 3780's current affinity list: 5,11
pid 3781's current affinity list: 5,11
pid 3782's current affinity list: 2
pid 3783's current affinity list: 8
pid 4752's current affinity list: 5,11

maybe because I did fwding core pinning after prox stacks created?

You have 2 forwarding cores on vRouter then do not expect more cores in dpdkvifstats output. Run the command to adjust output to yours configuration (number of vRouter cores) ./dpdkvifstats.py --all --cpu 2

I thought this is auto-calculated?

PrzemekGrygiel commented 3 years ago

It is not, was auto calculated with contrail 3.x based on config

ok got it.. we can calculate for any version based using this -

expr $(vif --get 0 | grep "RX queue errors to lcore" | xargs | cut -d' ' -f6- | wc -w) - 10

Good point
