opendevreviewMerged openstack/large-scale master: rabbitmq: add erlang scheduler recommendation  https://review.opendev.org/c/openstack/large-scale/+/85550807:19
fricklerfelixhuettner[m]: ^^ I missed that patch earlier, but it seems the spelling of the options is a bit off? I can create a followup if you agree07:41
amorinyes feel free07:42
amorinI think, the option is different if you set it on rabbit than on erlang vm07:44
amorin(you are talking about the +sbt and -sbt, right?)07:45
felixhuettner[m]it seems like that depends on how you call erlang (just to cause more confusion :) )07:57
felixhuettner[m]the official docker image directly calls `beam.smp` which uses a minus character07:57
felixhuettner[m]but if you call `erl` the docs say you should use a plus character07:57
felixhuettner[m]just tested that an this seems to fit reality07:59
felixhuettner[m]should we just add a note that this depends on how you start rabbitmq?08:00
amorinmaybe yes, to avoid confusion?08:01
amorinor maybe dont give any option, just say that this could/should be tuned and give a link to external doc?08:01
felixhuettner[m]i would still add a note since this is really non-obvious08:02
amorinack08:02
felixhuettner[m]i'll build a short patch08:03
fricklerit should also be "sbt" and not "stb" for the second variant I think08:05
felixhuettner[m]you are right, thanks08:05

fricklerI was also comparing this only to the other options we set in kolla-ansible, but if both variants are used somewhere, that's indeed confusing https://opendev.org/openstack/kolla-ansible/src/branch/master/ansible/roles/rabbitmq/defaults/main.yml#L8208:07
