QA » openQA Project

Motivation¶

Apache in prefork mode uses a lot of resources to provide mediocre performance. After nginx is deployed on OSD we should ensure that nginx helps to improve performance either with our default config or with additional config tweaks

Acceptance criteria¶

• AC1: It is known if Nginx default config or rate limiting features help to prevent OSD unresponsiveness

Suggestions¶

• Follow what was done for Nginx deployment on OSD in #130636 and #159654
• Take a look at what we already do or didn't want to do on o3, see #129490
• Monitor performance over some time, in particular if HTTP response graphs from openQA directly still show unresponsiveness windows or not
• Add changes to salt-states-openqa for any nginx config tweaks

Out of scope¶

• Any major research or big config tweaks for rate limiting, just some very basics if necessary at all
