Wires distributed tracing end-to-end. Backend exports OTLP/gRPC to a
collector, which tail-samples (errors + slow always, 10% rest) and
ships to Tempo. Grafana service-map dashboard pivots on the 4
instrumented hot paths.
- internal/tracing/otlp_exporter.go : InitOTLPTracer + Provider.Shutdown,
BatchSpanProcessor (5s/512 batch), ParentBased(TraceIDRatio) sampler,
W3C trace-context + baggage propagators. OTEL_SDK_DISABLED=true
short-circuits to a no-op. Failure to dial collector is non-fatal.
- cmd/api/main.go : init at boot, defer Shutdown(5s) on exit. appVersion
ldflag-overridable for resource attributes.
- 4 hot paths instrumented :
* handlers/auth.go::Login → "auth.login"
* core/track/track_upload_handler.go::InitiateChunkedUpload → "track.upload.initiate"
* core/marketplace/service.go::ProcessPaymentWebhook → "payment.webhook"
* handlers/search_handlers.go::Search → "search.query"
PII guarded — email masked, query content not recorded (length only).
- infra/ansible/roles/otel_collector : pin v0.116.1 contrib build,
systemd unit, tail-sampling config (errors + > 500ms always kept).
- infra/ansible/roles/tempo : pin v2.7.1 monolithic, local-disk backend
(S3 deferred to v1.1), 14d retention.
- infra/ansible/playbooks/observability.yml : provisions both Incus
containers + applies common baseline + roles in order.
- inventory/lab.yml : new groups observability, otel_collectors, tempo.
- config/grafana/dashboards/service-map.json : node graph + 4 hot-path
span tables + collector throughput/queue panels.
- docs/ENV_VARIABLES.md §30 : 4 OTEL_* env vars documented.
Acceptance criterion (Day 9) : login → span visible in Tempo UI. Lab
deployment to validate with `ansible-playbook -i inventory/lab.yml
playbooks/observability.yml` once roles/postgres_ha is up.
