 # Gatus Monitoring — Proposed Config
 
-**Status:** Draft / proposal. Not deployed yet.
+**Status:** Backend endpoint shipped in 2.6.49 (`backend@6c01a30`). Gatus config ready for deployment. Frontend `/api/health` proxy and ops deployment still pending.

 - The structure lets us add invariants later (e.g. `walletMonitor.ok`, `paymentRedisService.queueDepth`) without changing the URL.
 - Public exposure of counts (not addresses, not balances) is low-risk.

+**Backend work:** ✅ Complete (2.6.49). Includes `healthCheckService` with 5 checks, route wired in `app.ts`, rate-limiter + logging skip, and 5 route-level unit tests.

+### 2026-05-28 — backend@6c01a30 — Gatus monitoring: GET /api/health endpoint
+
+**Commits:** backend `19f7eb9` → `44579d6` → `6c01a30` (2.6.48 → 2.6.49)
+**Touched:**
+- Backend: `src/services/health/healthCheckService.ts`, `src/services/health/index.ts`, `src/app.ts`, `__tests__/health-check.test.ts`
+**Why:** Implement `GET /api/health` for Gatus monitoring. Exposes 5 checks (db, redis, rnChainRegistry, rnTokenRegistry, rnApi) in a single public endpoint. Status semantics: `ok` | `degraded` | `down` (503 when DB fails). Each check includes `latencyMs`; registry checks include counts. Rate limiter and request logging skip `/api/health`. 5 route-level unit tests cover ok/degraded/down transitions.
+**Verification:** `tsc --noEmit` clean. `npx jest __tests__/health-check.test.ts` — 5/5 pass.
+**Linked docs updated:** [[08 - Operations/Gatus Monitoring - Proposed Config]]
