# Console UI observability runbook (stub · 2025-11-29 demo)

## Dashboards (offline import)
- Grafana JSON: `docs/modules/ui/operations/dashboards/console-ui-observability.json` (import locally; no external data sources assumed).
- Panels to include: API latency (p95/p99), error rate, WebSocket/SSE connection count, asset load time, bundle size budget, Core Web Vitals (LCP/FID/CLS), and triage view render time.

## Key metrics
- `console_ui_http_request_duration_seconds_bucket{route}` — API call latency.
- `console_ui_http_requests_total{status}` — error rate tracking.
- `console_ui_websocket_connections` — active live session count.
- `console_ui_bundle_bytes{chunk}` — bundle size by chunk (ensures offline kit budget).
- `console_ui_core_web_vitals{metric}` — LCP/FID/CLS gauges.
- `console_ui_export_duration_seconds_bucket` — export trigger to download completion.

## Logs & traces
- Correlate by `correlationId` (propagated from API) and `tenant`. Include `feature` (triage, findings, policy) and `route` fields.
- Traces disabled by default for air-gap; enable by pointing OTLP endpoint to on-prem collector and setting `Telemetry:ExportEnabled=true`.

## Health/diagnostics
- `/health/liveness` and `/health/readiness` (UI backend) must return 200; readiness checks asset storage + API gateway reachability.
- `/status` exposes build version, commit, feature flags; ensure it matches the offline bundle manifest when shipping sealed kits.
- Frontend self-check: open `/health/ui` to verify core bundles are reachable and integrity hashes match manifest.

## Alert hints
- p99 API latency > 1s for `/api/findings` or `/api/policy`.
- SSE/WS disconnect rate > 2% over 5m window.
- Bundle size > 3.5 MB for main chunk after gzip (offline kit budget breach).
- Core Web Vitals: LCP > 2.5s, CLS > 0.1 on internal demo dataset.

## Offline verification steps
1) Import Grafana JSON locally; point to Prometheus scrape labeled `console-ui`.
2) Run `npm run build -- --configuration=production` (or offline kit build) and verify bundle hashes against manifest used by `/health/ui`.
3) Fetch `/status` and compare commit/version to the static asset manifest embedded in the offline kit.
