-   - 错误: `Missing required config: challengeUuid`
-   - 解决: 在 Monitor 中注册服务器并配置 challengeUuid

-
-3. **无法连接到 Monitor**

-# HarborForge OpenClaw Server Connector Plugin — Project Plan
+# Monitor Server Connector Plan
 
-## 1) Goal
-Provide a secure, lightweight plugin/agent that connects servers to HarborForge Monitor, streams telemetry in real time, and falls back to HTTP heartbeat when WebSocket is unavailable.
+## Current design
 
-## 2) Scope
-- **Handshake + auth** using backend-issued challenge + RSA-OAEP encrypted payload.
-- **WebSocket telemetry** to `/monitor/server/ws`.
-- **HTTP heartbeat** to `/monitor/server/heartbeat` as fallback.
-- **System metrics**: CPU/Mem/Disk/Swap/Uptime/OpenClaw version/Agents list.
-- **Retry & backoff**, offline handling, and minimal local state.
+The plugin uses:
 
-## 3) Non-Goals
-- No UI in the plugin.
-- No provider billing calls from plugin.
-- No multi-tenant auth beyond challenge + server identifier.
+- **HTTP heartbeat** to `/monitor/server/heartbeat-v2`
+- **API Key authentication** via `X-API-Key`
+- **Gateway lifecycle hooks**: `gateway_start` / `gateway_stop`
 
-## 4) Architecture
-```
-plugin/
-  config/          # load config & secrets
-  crypto/          # RSA-OAEP encrypt/decrypt helpers
-  collector/       # system + openclaw metrics
-  transport/       # ws + http heartbeat
-  state/           # retry/backoff, last sent, cache
-  main.ts|py        # entry
-```
+## No longer used
 
-### 4.1 Config
-- `backend_url`
-- `identifier`
-- `challenge_uuid`
-- `report_interval_sec` (default: 20-30s)
-- `http_fallback_interval_sec` (default: 60s)
-- `log_level`
+The following design has been retired:
 
-### 4.2 Security
-- Fetch public key: `GET /monitor/public/server-public-key`
-- Encrypt payload with RSA-OAEP
-- Include `nonce` + `ts` (UTC) to prevent replay
-- **Challenge valid**: 10 minutes
-- **Offline threshold**: 7 minutes
+- challenge UUID
+- RSA public key fetch
+- encrypted handshake payload
+- WebSocket telemetry
 
-## 5) Communication Flow
-### 5.1 Handshake (WS)
-1. Plugin reads `identifier + challenge_uuid`.
-2. Fetch RSA public key.
-3. Encrypt payload: `{identifier, challenge_uuid, nonce, ts}`.
-4. Connect WS `/monitor/server/ws` and send `encrypted_payload`.
-5. On success: begin periodic telemetry push.
+## Runtime flow
 
-### 5.2 Fallback (HTTP)
-If WS fails:
-- POST telemetry to `/monitor/server/heartbeat` with same payload fields.
-- Retry with exponential backoff (cap 5–10 min).
+1. Gateway loads `harborforge-monitor`
+2. Plugin reads config from OpenClaw plugin config
+3. On `gateway_start`, plugin launches `server/telemetry.mjs`
+4. Sidecar collects:
+   - system metrics
+   - OpenClaw version
+   - plugin version
+   - configured agents
+5. Sidecar posts telemetry to backend with `X-API-Key`
 
-## 6) Telemetry Schema (example)
-```
+## Payload
+
+```json
 {
-  identifier: "vps.t1",
-  openclaw_version: "x.y.z",
-  cpu_pct: 12.5,
-  mem_pct: 41.2,
-  disk_pct: 62.0,
-  swap_pct: 0.0,
-  agents: [ { id: "a1", name: "agent", status: "running" } ],
-  last_seen_at: "2026-03-11T21:00:00Z"
+  "identifier": "vps.t1",
+  "openclaw_version": "OpenClaw 2026.3.13 (61d171a)",
+  "plugin_version": "0.1.0",
+  "agents": [],
+  "cpu_pct": 10.5,
+  "mem_pct": 52.1,
+  "disk_pct": 81.0,
+  "swap_pct": 0.0,
+  "load_avg": [0.12, 0.09, 0.03],
+  "uptime_seconds": 12345
 }
 ```
-
-## 7) Reliability
-- Automatic reconnect on WS drop
-- HTTP fallback if WS unavailable > 2 intervals
-- Exponential backoff on failures
-- Local cache for last successful payload
-
-## 8) Deployment Options
-- **Systemd service** (preferred for VPS)
-- **Docker container** (optional)
-- Single-binary build if using Go/Rust
-
-## 9) Milestones
-**M1 – POC (2–3 days)**
-- CLI config loader + HTTP heartbeat
-- See online + metrics in Monitor
-
-**M2 – WS realtime (2–3 days)**
-- Full handshake + WS streaming
-- Reconnect & fallback logic
-
-**M3 – Packaging (1–2 days)**
-- systemd unit + sample config
-- installation script
-
-**M4 – Hardening & Docs (1–2 days)**
-- logging, metrics, docs
-- troubleshooting guide
-
-## 10) Deliverables
-- Plugin source
-- Config template + systemd unit
-- Integration docs
-- Test script + example payloads
-
-## 11) Open Questions
-- Preferred language (Go/Python/Node/Rust)?
-- How to read OpenClaw agent list (API vs local state)?
-- Required log format / retention?
-
----
-
-**Next step:** confirm preferred runtime (Go/Python/Node) and I will scaffold the project structure + first heartbeat implementation.
