A per-site Analytics tab showing traffic and error analytics, computed on-demand from the site's Apache access log — Docker-correct. Architectural pivot: managed WP sites are wordpress:*-apache containers on localhost:PORT with NO per-site nginx, so the roadmap's "nginx access log" premise does not hold. The official image symlinks Apache's access log to the container's stdout, so `docker logs` is the source. New WpAnalyticsService.get_traffic(container_name, hours) pulls `docker logs --tail 20000 --since <h>` (hard 15s timeout; reads only stdout to separate the access log from the stderr error_log; returncode-checked so a stopped/missing/remote-agent container degrades to an accurate note) and parses the Apache combined log on-demand — no store, collector, or migration. Returns requests, unique visitors, bandwidth, status distribution (2xx/3xx/4xx/5xx), 404s, bot %, error rate, top URLs (grouped by route; query strings stripped so visitor tokens are never surfaced), and a continuous hourly requests/errors series. Route GET /sites/<id>/analytics?hours= (owner/admin-guarded), client getSiteAnalytics, and a new Analytics tab on the site detail (stat cards + a recharts requests/errors AreaChart + status codes + Top URLs) with graceful empty/timeout/unavailable states. Also supplies the 5xx/error-rate signal #27's "error spike" rule needs. Deferred (not in the default access log): PHP fatals (need wp-content/debug.log via a WP_DEBUG toggle, #30), response time / slow pages (need a %D LogFormat), cache hit ratio (#22/#23). History is point-in-time over the retained container log; a persistent time-series collector is a clean follow-up. Review fixes (3-lens): docker-logs timeout + memory cap (single-worker safety); accurate unavailable note via returncode; query-string token stripping. Verified: backend py_compile, frontend lint + build. Not runtime-exercised on a real Docker host (Windows dev). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
