Description Alex Katz 2020-10-12 14:15:31 UTC

BZ1768558 brought a new `ps` output enhancement to list neutron API and RPC workers separately. Unfortunately, there was RPC worker's fix has only been integrated but the API workers are not shown correctly:

Comment 1 Bernard Cafarelli 2021-01-08 09:04:22 UTC

Fix in progress upstream, I tested a similar change quickly on a 16.1 setup and it did set process title properly for API WSGI processes

Comment 3 Bernard Cafarelli 2021-01-15 13:08:39 UTC

I tested fix manually applied to neutron_api container on latest 13. API workers also now have proper process title:
