Maintainer resolved E1 as variant B: the public vitals sink + client collection
must be OFF by default (else client_metrics grows unbounded on a self-host deploy
with no external pruner, via an unauthenticated public endpoint).
- F1: new operator flag CLIENT_TELEMETRY_ENABLED (default OFF), SEPARATE from
METRICS_PORT (Grafana reads the table directly, independent of the scrape port).
ClientTelemetryModule.register() provides VitalsController ONLY when the flag is
true (route absent otherwise); the flag reaches the client via window.CONFIG
(config.ts isClientTelemetryEnabled), and initVitals() early-returns when off.
- F2/F3 [throttler]: this repo's ThrottlerGuard applies EVERY named throttler to
every guarded route unless skipped. The new VITALS bucket therefore (a) newly
bound collab-token → 429 behind shared/NAT IPs, and (b) the vitals route didn't
skip the stricter public-share-ai (5/min) bucket → effective 5/min not 120.
Fix (additive, global config unchanged): vitals.controller @SkipThrottle the
other buckets + @Throttle VITALS 120/min; collab-token adds VITALS_THROTTLER to
its existing @SkipThrottle (restoring its prior effectively-unthrottled state).
- F4: metrics node:http server is closed on shutdown (MetricsServerLifecycle
OnModuleDestroy → closeMetricsServer(), fired by enableShutdownHooks).
- F5: docSize outside [0, int4-max] drops to null (keeping the event) instead of
overflowing int4 and failing the WHOLE batch insert (+ 2 tests).
- F6: .env.example documents METRICS_PORT (no default — unset = subsystem OFF) +
CLIENT_TELEMETRY_ENABLED; fixed the inaccurate "default 9464" wording.
- F7: disabled/non-sampled sessions install ZERO observers — isVitalsActive()
(enabled && sampled) gates reportClientMetric AND the page-editor
measurePageOpen + dispatchTransaction wrapping.
- F8: kept db.d.ts hand-added (wontfix) — this repo HAND-CURATES db.d.ts (verified
across recent fork migrations a32fba63/8c5b57eb/fdeede00); codegen would be the
deviation. The ClientMetrics interface maps the migration 1:1.
Gate: server tsc 0, client tsc 0, server metrics/vitals/telemetry/throttle 21
tests, client route-template 5. No new deps.
