# Export Center observability runbook (stub · 2025-11-29 demo)

## Dashboards (offline import)
- Grafana JSON: `docs/modules/export-center/operations/dashboards/export-center-observability.json` (import locally; no external data sources assumed).
- Planned panels: export job duration p95/p99, bundle size histogram, registry push latency, provenance/attestation verification failures, queue depth, and error rate per profile.

## Key metrics
- `export_job_duration_seconds_bucket{profile}` — export duration by profile.
- `export_bundle_size_bytes_bucket{profile}` — bundle size distribution.
- `export_registry_push_latency_seconds_bucket{profile}` — registry push latency.
- `export_attestation_failures_total{reason}` — DSSE/provenance verification failures.
- `export_queue_depth` — pending export jobs.
- `export_manifest_publish_total{result}` — manifest publish successes/failures.

## Logs & traces
- Correlate by `exportId`, `profile`, `tenant`; include `bundleDigest`, `attestationStatus`, `registry`. Traces disabled by default; enable OTLP to on-prem collector when permitted.

## Health/diagnostics
- `/health/liveness` and `/health/readiness` (export service) check storage, registry reachability, and attestation verification path.
- `/status` exposes build version, commit, feature flags; verify against offline bundle manifest.
- Verification probe: `stella export bundle verify --manifest <path>` once bundle available; validate hashes against manifest.

## Alert hints
- Export job duration p99 > target SLA per profile.
- Attestation verification failures > 0 over 10m.
- Registry push latency spikes or error rate > threshold.
- Queue depth growth without completion.

## Offline verification steps
1) Import Grafana JSON locally; point to Prometheus scrape labeled `export-center`.
2) Run `stella export bundle --profile <profile> --manifest out/manifest.json` and verify hashes via `jq -r '.files[].sha256'` against generated bundles.
3) Fetch `/status` and compare commit/version to offline bundle manifest.
