Deploying WebSensor on MacLustr
WebSensor runs as three PM2 processes on one node (M4M64b), published through the MacLustr Tunnel (WireGuard +
Caddy on the OVH gateway BHS64, www.websensor.io; ngrok was retired on 2026-09-10), orchestrated by mld from the
M1M32 gateway.

DNS / tunnel
www.websensor.io→ A record to BHS64 (51.161.112.61);mld deploy/moverepoints the Caddy route to the current node automatically (tunnel.domainin the manifest). The apexwebsensor.ioshould redirect towww.- WebSocket upgrades traverse Caddy without configuration; the API sends a heartbeat every 25 s and clients
replay missed events with
{"since": lastSid}after a reconnection.
Operations
- Logs:
mld logs websensororssh M4M64b pm2 logs websensor-engine. - Registry edits: change
config/sources.yaml, redeploy (sync runs in post-sync) orssh M4M64b "cd ~/apps/websensor && node node_modules/tsx/dist/cli.mjs apps/engine/src/cli.ts sync". Seed sensors removed from the YAML are disabled automatically; discovery-created sensors are kept. - Discovery:
cli.ts discover [sourceId…];cli.ts probe <domain>for a dry run. - Metrics: engine
http://127.0.0.1:8262/metrics, API/api/metrics(Prometheus text). Public health dashboard:/healthon the site,/api/v1/health/connectors. - Budgets:
WS_LLM_DAILY_CALL_BUDGET(Claude calls/day),WS_SCRAPFLY_DAILY_BUDGET(Scrapfly calls/day, ~30 credits each with anti-bot). Both counters reset at UTC midnight and are visible inmetrics_daily. - Backups:
pg_dump websensor+~/websensor-data/blobs(content-addressed; safe to rsync incrementally). - Retention:
sensor_runsunchanged/304 rows are pruned after 14 days, all runs after 60 days. Raw bodies of snapshots that never produced an event are pruned afterWS_RETENTION_RAW_DAYS(21) — canonical forms, hashes, changes and events are kept; event snapshots are never pruned.cli.ts prune-blobsruns it by hand. - After a deploy that changes alias or scoring rules:
cli.ts relink-entities 7(re-resolves mentioned entities) andcli.ts refresh-clusters(breaking / developing / confirmed states). - Operations dashboard:
/ops(token) andGET /api/v1/admin/ops; connector dry-runPOST /api/v1/admin/sensors/test; bulk importPOST /api/v1/admin/sources/import?dry_run=1(JSON or YAML) — imported sensors start as PENDING and become ACTIVE after their first successful check.
