Stage discovered the wrong default at runtime: tcp-ingestion's compiled
default REDIS_TELEMETRY_STREAM is 'telemetry:teltonika' but processor's
was 'telemetry:t', so the two services were talking past each other —
tcp-ingestion publishing to one stream, processor reading another empty
one. The deploy stack now pins both to the same value via a shared env
var, but the processor's compiled default should also match so local
development and the integration test stay aligned with reality.
Changes:
- src/config/load.ts — default changed to 'telemetry:teltonika'
- .env.example — same
- test/config.test.ts — default-value assertion updated
- planning docs (ROADMAP, phase-1 README, tasks 03/08/10, phase-3 README) —
occurrences of 'telemetry:t' replaced with 'telemetry:teltonika'
The deploy stack remains the single source of truth via the shared
REDIS_TELEMETRY_STREAM env var. Compiled defaults are belt-and-braces.
src/observability/metrics.ts — full prom-client implementation. All 10
Phase 1 metrics registered (processor_consumer_reads_total,
_records_total, _lag, _decode_errors_total, processor_position_writes_total
{status}, _write_duration_seconds, processor_acks_total,
processor_device_state_{size,evictions_total}) plus nodejs_* defaults.
node:http server with /metrics, /healthz, /readyz. /readyz checks
redis.status === 'ready' AND a 5s-cached SELECT 1 Postgres probe.
processor_consumer_lag sampled every 10s via XINFO GROUPS, falling back
to a no-op when the consumer group hasn't been created yet.
src/main.ts — replaces the trace-logging shim with createMetrics() and
startMetricsServer(); shutdown closes the metrics server before
redis.quit() and pool.end().
test/metrics.test.ts — 22 unit tests: exposition format, every metric
type behaviour, all four HTTP endpoint paths including /readyz 503 cases.
test/pipeline.integration.test.ts — testcontainers Redis 7 +
TimescaleDB latest-pg16. Four scenarios: happy path with bigint+Buffer
attribute round-trip, idempotency on (device_id, ts), malformed payload
stays in PEL (decode_errors_total increments), writer failure → retry
(weaker variant per spec: stop Postgres before publish, restart, verify
row appears). Skip-on-no-Docker pattern verified — exits 0 without
Docker.
Dockerfile — multi-stage matching tcp-ingestion. EXPOSE 9090 only,
HEALTHCHECK on /readyz, image-source label points at processor repo.
.gitea/workflows/build.yml — single-job workflow mirroring
tcp-ingestion. Path filters cover src/, test/, build config, Dockerfile.
Portainer webhook step uncommented for :main auto-deploy.
compose.dev.yaml — local-build variant with Redis + TimescaleDB +
processor-dev for verifying Dockerfile changes without the registry
round-trip.
README.md — fleshed out from stub: quick-start, Docker build, deployment
note, env vars, tests (unit vs. integration), CI behavior. Flags the
deploy-side change needed: deploy/compose.yaml needs a TimescaleDB
service and a processor service entry added.
Verification: typecheck, lint clean; 134 unit tests passing across 8
files (+22 from this batch). pnpm test:integration runs cleanly under
the no-Docker skip pattern.
Phase 1 is now complete. Service is pilot-ready.
