CI/CD Pipeline Observability & Guardrails
Metrics Lead time, MTTR, change failure rate, deploy frequency. Stage timing (queue, build, test, deploy); flake rate; retry counts. Tracing & logs Trace pipeline executions with build SHA, branch, trigger source; annotate stage spans. Structured logs with status, duration, infra node; keep artifacts linked. Guardrails Quality gates (tests, lint, security scans) per PR; fail fast on criticals. Retry budget per job to avoid infinite flake loops. Rollback hooks + auto-stop on repeated failures. Ops Parallelize where safe; cache dependencies; pin tool versions. Alert on SLA breaches (queue time, total duration) and rising flake rates. Keep dashboards per repo/team; trend regressions release to release.
