Ticket 10 verification surfaced runtime issues that static validation
missed; all verified against running Docker stack (Vector 0.43 + OO 0.92.2):
- Rewrite VRL for Vector 0.43: no coalesce/default funcs, merge!/replace!
for guarded fallible calls, no two-value parse_json destructuring
- Quote env-interpolated sink credentials (empty env left a bare YAML null)
- Fix logs sink URI: OO needs /api/{org}/{stream}/_json (stream segment
was missing, causing 404); logs now land in contract_check stream
- Replace OPENOBSERVE_AUTH_TOKEN with root email/password Basic auth:
prometheus_remote_write ignores request.headers, so remote-write got 401
- Update .env.example, DEPLOY.md, ARCHITECTURE.md, ticket 05 accordingly
Verified live: logs with service + correlation_id searchable in
OpenObserve; contract_check_* metrics queryable via its Prometheus API;
no outbound port 4318 connections from app containers.
- core/telemetry.py is now a no-op (no opentelemetry imports); entrypoints
no longer call setup/shutdown telemetry
- Remove all opentelemetry-* deps from pyproject groups; regenerate uv.lock
- Drop otel_exporter_otlp_endpoint/otel_service_name settings; sentry and
auth use "contract-check" instead
- Stop publishing worker metrics ports; bind API metrics to 127.0.0.1 by
default via API_METRICS_BIND_HOST
- Replace otel-collector with Vector in observer profile (docker_logs +
prometheus_scrape -> OpenObserve); add deploy/observability/vector-config.yaml
- Update .env.example, docs (ARCHITECTURE, DEPLOY), README, Makefile
- Rewrite tests/unit/test_telemetry.py for the no-op implementation
