vm-health-check.sh:
- check_gpu(): nvidia-smi probe; "CPU-only" OK on this VM (no GPU)
- check_image_freshness(): flag containers running images >30d old.
Skips third-party images (gitea, grafana, prom, mcr.microsoft, axllent,
caddy, traefik, valkey, cadvisor) — they have their own rebuild cadence.
Currently flags 19 stale product images (~60d old).
chaos-validation.sh:
- Monthly chaos test: kill PID 1 in chronomind-web, wait up to 35 min
for docker-health-watchdog to detect + restart. Telegram pass/fail.
- Refuses to run if target not healthy. systemd timer fires 1st of month
at 10:00 UTC (after 08:00 weekly digest).
vm-io-anomaly-check.sh:
- 6h avg sda write rate; transition alerts at WARN (1 GB/hr) /
CRIT (2.5 GB/hr). De-dupes via /var/log/vm-io-anomaly-state so the
alert fires once per transition, not every 6h. Current baseline:
~1.94 GB/hr (orphan-container state-file writes; see Phase 0.3).
- Reports recovery to OK when rate drops back.
vm/page.tsx: gpu + image_freshness added to CHECK_META so they render
with proper icon/label and slot into CHECK_ORDER.
