- /api/health returns {status, uptime_sec, version, event_count,
ingest_rate_per_sec, ws_clients, tailer_files_watched, dedup_dropped,
process_resident_memory_bytes}; returns HTTP 503 with status='overloaded'
when maxEventCount is exceeded
- /api/metrics exposes the same counters in Prometheus text format;
fabric_status=0 when overloaded
- Add ServerMetrics.eventCount setter so both endpoints sync from store.size
(fixes fabric_event_count in /api/metrics showing 0 when events added directly)
- Wire --max-events CLI option into `fabric web`; pass maxEventCount and
deduplicator to createWebServer so the memory-bomb guard and dedup_dropped
reporting are actually activated
- Track tailerFilesWatched: set after tailer.start() and update on each event
for DirectoryTailer (uses activeFiles.length getter)
- Add import for Node net module used by systemd watchdog notify
- Add tests: overload guard returns 503, within-limit returns 200, Prometheus
reflects fabric_status=0 when overloaded
systemd service already has Restart=on-failure + WatchdogSec=30 (scripts/fabric-web.service);
liveness guard in server.ts calls process.exit(1) after 3 consecutive overload
checks, triggering systemd restart.
