QA » openQA Project

Motivation¶

Similar as in #160877 but concerning the server rather than tooling.

Did we managed do DoS the server? Do we need to tweak the nginx even more?

Acceptance criteria¶

• AC1: No significant numbers of 502 responses recorded in https://monitor.qa.suse.de/d/WebuiDb/webui-summary?orgId=1&viewPanel=80 even during openQA-webui services restarts

Suggestions¶

• Wait for #162611 "Easy local development setup for comparing apache2+nginx as openQA web proxy"
• Check and unsilence web UI: Too many 5xx HTTP responses alert after making nginx more resilient
• Look into older tickets where ideas and limitations have been mentioned already
• If it's not possible with nginx switch back to apache or traefik or whatever is fitting
• Look into https://nginx.org/en/docs/http/ngx_http_upstream_module.html
• Have a look if the caddy webserver can do what we want.

Rollback steps¶

• Unsilence rule_uid=http_response_5xx_alert silence on https://monitor.qa.suse.de/alerting/silences
