 ### 🟠 Gateway Data Collection Service — HIGH
 **Priority:** HIGH  
-**Status:** IN PROGRESS  
+**Status:** DONE ✅  
 **Added:** 2026-05-10 by Ripley
+**Completed:** 2026-05-11
 
-**Description:**
-Port the dashboard's Go data collection (`refresh.go`, `refresh_sessions.go`, `refresh_tokens.go`, etc.) to Python services that poll the OpenClaw gateway.
-
-**Implementation Notes:**
-- Create `app/services/monitoring/gateway_collector.py`
-- Reuse existing `gateway_rpc.py` for all RPC calls
-- Poll: usage.cost, usage.status, cron.list/status, sessions.list/preview, agents.list, health, status
-- Run as background asyncio task with configurable intervals
-- Store collected data in new PostgreSQL models
+GatewayCollectorService created in `src/backend/app/services/monitoring/`. Background asyncio task polls gateway RPC endpoints (cost, cron, sessions, health) and upserts into monitoring models. Configurable intervals via env vars. Startup/shutdown integrated into main.py lifespan.

 # Mission Control — Changelog
 
+## v0.0.4
+
+### Added
+- **Gateway Data Collection Service** — Background asyncio task that polls gateway RPC endpoints and stores results in monitoring models
+  - `gateway_collector.py` — GatewayCollectorService class with per-endpoint collection methods (cost, cron, session, health)
+  - `models.py` — Pydantic schemas for parsing gateway RPC responses into typed Python objects
+  - `__init__.py` — Package init, exports GatewayCollectorService
+- **Collector startup/shutdown** — Added to main.py lifespan; launches collector as background task when gateways exist
+- **Configurable collection intervals** via env vars: COLLECTION_INTERVAL_COST (300s), COLLECTION_INTERVAL_CRON (60s), COLLECTION_INTERVAL_SESSION (30s), COLLECTION_INTERVAL_HEALTH (60s)
+- **Upsert pattern** — All DB writes use insert-or-update to avoid duplicate records
+
+### Fixed
+- Model FK definitions in monitoring.py and alert_rules.py: replaced `Column(UUID, ForeignKey(...))` with `Field(foreign_key=...)` to match codebase pattern
+- Added missing `gateway_id` field to AlertRule model
+- Removed OpenClawDBService inheritance from GatewayCollectorService (uses session factory pattern)
+- Cleaned up duplicate/conflicting imports in collector
+

+- **Phase 2: Gateway Data Collection Service**
+- Created `src/backend/app/services/monitoring/` package with collector, Pydantic models, and init
+- GatewayCollectorService: background asyncio task polling gateway RPC endpoints
+- Collection methods: cost (usage.cost + usage.status), cron (cron.list), sessions (sessions.list + preview), health (health + status)
+- Upsert pattern for all DB writes to avoid duplicates
+- Configurable intervals via env vars (COST=300s, CRON=60s, SESSION=30s, HEALTH=60s)
+- Collector startup/shutdown integrated into main.py lifespan
+- Fixed model FK definitions: replaced Column(UUID, ForeignKey(...)) with Field(foreign_key=...)
+- Added missing gateway_id field to AlertRule model
+- Backend builds and runs successfully, collector logs correctly

 ## v0.0.3 — 2026-05-11
 - **Phase 2: Monitoring database models**
 - Add 7 new SQLModel tables for monitoring data collection
