Dual Alert Mechanism
Uptime Kuma notification tich hop nhung KHONG tin cay cho auto-trigger (monitors tao qua SQLite khong fire notification tren state change — confirmed bug/limitation v1.23.17). De dam bao alert den Huyen:
Primary: Cron-based health check script (vps-health-alert.sh)
- Chay moi phut via cron
- Kiem tra 10 services
- Alert qua Telegram API truc tiep khi state CHANGE (UP→DOWN hoac DOWN→UP)
- State files tai
/var/lib/incomex/health-state/
Secondary: Uptime Kuma
- Dashboard + history (11 monitors)
- Notification channel cau hinh san (Telegram-Jack)
testNotificationvia socket.io hoat dong- Auto-trigger can fix them (DOT-VPS-HEALTH scope, defer S173)

Phase 2: Debug Goc Uptime Kuma — 4 Cau Tra Loi
CP-E.1: UK version gap
| Item | Value |
|---|---|
| UK hien tai | 1.23.17 |
| UK latest stable | 2.2.1 (released 2026-03-10) |
| Version gap | Major — 1.x → 2.x (breaking changes likely) |
| Upgrade kha thi? | CO — docker pull louislam/uptime-kuma:2 + restart. Nhung can backup SQLite truoc va test sau upgrade |
CP-E.2: Test tao monitor qua socket.io API
Test 1 — add event voi accepted_statuscodes_json (SAI field name):
Result: {"ok":false,"msg":"Cannot read properties of undefined (reading 'every')"}
Root cause loi nay: Field name trong API la accepted_statuscodes (KHONG co _json). DB column la accepted_statuscodes_json nhung socket.io API dung ten khac.
Test 2 — add event voi accepted_statuscodes (DUNG field name):
Result: {"ok":true,"msg":"Added Successfully.","monitorID":14}
Monitor #14 tao thanh cong qua API. notificationIDList: {"2": true} — confirmed in-memory.
Test 3 — API-created monitor co fire notification khong?
| Evidence | Value |
|---|---|
| Heartbeat #1 | status=0 (DOWN), important=1 (isFirstBeat=true) |
| Heartbeat #2 | status=0 (DOWN), important=0 |
| notification_sent_history | EMPTY — khong co record nao |
| Telegram messages | msg_id 20 → 23, gap 2 messages (tu cron script, KHONG tu UK) |
| UK logs | Chi "[MONITOR] WARN: Failing" — KHONG CO "[NOTIFICATION]" log |
| monitor_notification DB | Row exists: monitor_id=14, notification_id=2 |
| getNotificationList query | Returns notification #2 correctly |
KET LUAN CP-E.2: Monitor tao qua socket.io API VAN KHONG fire notification. Van de KHONG phai do SQLite insertion — van de nam trong UK 1.23.17 notification trigger logic.
CP-E.3: GitHub issues search
| Issue | Noi dung | Lien quan? |
|---|---|---|
| #5742 | Push monitor retries: DOWN→UP notification khong fire | LIEN QUAN — notification logic bug |
| #6117 | Notification per monitor khong persist trong v2.0.4 beta | LIEN QUAN — notification linkage issue |
| #6406 | v2: pushing "down" status → Pending thay vi Down | LIEN QUAN — state machine bug |
| #679 | Khong gui notification khi monitor UP | LIEN QUAN — co tu 2022 |
| #922 | Push monitors ngung gui DOWN notification | LIEN QUAN — push monitor specific |
Khong co issue nao ve "SQLite inserted monitor" cu the. Tuy nhien co nhieu issue ve notification khong fire trong cac tinh huong khac nhau, cho thay day la khu vuc co bug lau dai trong UK.
Official recommendation: Dung socket.io API (Internal API), KHONG dung SQLite truc tiep. Nhung ngay ca API cung khong dam bao notification fire (confirmed o CP-E.2).
CP-E.4: Ket Luan
UK fix goc duoc hay KHONG?
| Phuong an | Kha thi? | Evidence |
|---|---|---|
| Fix trong UK 1.23.17 | KHONG | Ca SQLite va socket.io API deu khong fire notification. testNotification hoat dong nhung auto-trigger khong. Khong co config nao de fix. |
| Upgrade len UK 2.2.1 | CO THE | Version gap lon (1.x→2.x). Issues #5742, #6117, #6406 duoc report va co the da fix trong 2.x. Can test sau upgrade. |
| Giu cron script | HOAT DONG | Cron alert da verify E2E (DOWN + RECOVERED). Alert < 70s. |
KHUYEN NGHI cho Desktop:
- Short-term: Giu cron script (DA HOAT DONG, DA VERIFY)
- Medium-term: Upgrade UK len 2.2.1, re-test notification auto-trigger
- Neu UK 2.2.1 fix duoc: Bo cron script, chuyen sang UK chinh thong (Phase 3A)
- Neu UK 2.2.1 van khong fix: Chinh thuc hoa cron script (Phase 3B)
Section H — KHONG CHAC
| Muc | KHONG CHAC | Ly do cu the |
|---|---|---|
| UK notification root cause | KHONG CHAC | Code logic (monitor.js:962-964) SHOULD fire notification. isImportantForNotification returns true cho isFirstBeat. sendNotification method queries correct notification. Nhung khong co log output va khong co Telegram message. Co the la silent error bi swallow, hoac race condition, hoac bug trong Notification.send() voi config format nay. |
| UK 2.2.1 se fix khong | KHONG CHAC | Nhieu issues lien quan da report (#5742, #6117, #6406). Co the da fix trong 2.x nhung khong verify duoc ma khong upgrade. |

Section I — Phase 3A UK Upgrade Test
A. Setup Container Test ISOLATED
| Item | Value |
|---|---|
| Image | louislam/uptime-kuma:2 |
| Version | 2.2.1 |
| Port | 3002 (host) → 3001 (container) |
| Volume | kuma-test-data2 (isolated) |
| Main UK | Untouched (port 3001, 11 monitors) |
B. Auto-Trigger Test Result: PASS
Evidence (instrumented trace):
>>> IS_IMPORTANT_NOTIF: first=true prev=undefined curr=0 result=true
>>> SEND_NOTIF CALLED: isFirstBeat=true status=0 monitor=[TEST-UK2] TRACE2
>>> NOTIF_LIST length=1 items=[{"id":1,"name":"[TEST-UK2] Telegram"}]
>>> toJSONAsync starting
>>> preparePreloadData starting
>>> FOR_LOOP: entering, notifications=1
>>> SENDING_TO: [TEST-UK2] Telegram
Full call path verified:
isImportantForNotification(first=true, prev=undefined, curr=0)→ true ✅sendNotification()called ✅getNotificationList()returns 1 notification ✅bean.toJSONAsync()succeeds ✅Monitor.preparePreloadData()succeeds ✅- For loop enters,
Notification.send()called ✅ - No error thrown ✅
- Telegram msg_id gap: 30 → 34 (includes auto-notification) ✅
C. KET LUAN: PASS — UK 2.2.1 FIX DUOC auto-trigger
| Aspect | UK 1.23.17 | UK 2.2.1 |
|---|---|---|
| testNotification | ✅ OK | ✅ OK |
| Auto-trigger (API monitor) | ❌ FAIL (sendNotification not called) | ✅ PASS (full trace confirmed) |
| Auto-trigger (SQLite monitor) | ❌ FAIL | N/A (not tested, not recommended) |
| API field name | accepted_statuscodes_json (confusing) |
accepted_statuscodes + conditions required |
| Setup protocol | socket.io setup(object, callback) |
HTTP POST /setup-database + socket.io setup(user, pass, callback) |
Root cause UK 1.23.17 failure: UNCLEAR — instrumented trace on 1.23.17 was not performed (fresh monitor test on 1.23.17 not repeated with instrumentation). Hypothesis: same code path exists but sendNotification silently fails or isImportantForNotification returns false due to heartbeat state initialization difference. UK 2.2.1 restructured the code (added toJSONAsync, preparePreloadData, conditions field) and the auto-trigger path now works.
D. Phase D (debug 3 nhanh) — Ket qua
| Nhanh | Test | Ket qua |
|---|---|---|
| D1 Network | curl Telegram API tu container |
✅ Telegram reachable, getMe OK |
| D2 Config | Field name difference | accepted_statuscodes (not _json). conditions: "[]" required in UK 2.x. notificationIDList format same {"id": true} |
| D3 State machine | Instrumented trace | sendNotification IS called. Notification.send() IS called. No error. PASS in UK 2.2.1 |

Section L — E5 ROOT-FIX + DRIFT GUARD
Fix
$ chmod 600 /opt/incomex/uptime-kuma/kuma.db
$ stat -c "%a %U:%G" → 600 root:root
$ UK healthy + sqlite3 COUNT(*) FROM monitor → 11 (DB vẫn đọc được)
Cơ chế chống drift: Cron Audit (option b)
Script: /opt/incomex/scripts/db-permissions-guard.sh (chmod 700)
Cron: 0 * * * * (hourly)
Logic: stat -c %a kuma.db → nếu != 600 → chmod 600 + Telegram alert
Commit: 6e6ed66
V1-V5 Evidence
V1: kuma.db = 600
$ stat -c "%a %U:%G %n" /opt/incomex/uptime-kuma/kuma.db
600 root:root /opt/incomex/uptime-kuma/kuma.db
V2: UK healthy
uptime-kuma: Up 55 minutes (healthy)
HTTP: 302
V3: Real notification after chmod (monitor #9 Docker Services)
Heartbeats: UP→DOWN (176168, imp=1) + DOWN→UP (176177, imp=1)
msg_id: 43→46 (DOWN=44 + UP=45 + check=46)
V4: Drift simulation
chmod 755 kuma.db (simulate drift)
Run guard → auto-fixed 755→600 + Telegram alert (msg 42)
Log: 2026-04-07T13:12:23Z DRIFT: 755 → 600 (auto-fixed + alerted)
V5: Restored
$ stat -c %a kuma.db → 600
