## FRO Watchdog

### 今日主要成果

- FRO Watchdog 模块完成并正式关闭。
- systemd watchdog timer 已建立并启用。
- Watchdog 每约 30 秒检查一次 FRO `/dashboard`。
- 连续 3 次健康检查失败后自动重启 `remoteoffice` Docker container。
- 重启后会再次检查 FRO 是否恢复。
- Watchdog 正常运行已连续验证。
- `/run/fro-watchdog.failures` 当前为 `0`。
- IEI Event Log Writer 已建立并测试成功。
- Watchdog 已接入 Event Log，记录异常、重启及恢复事件。
- 原 Watchdog script 已建立备份。
- 更新后的 Watchdog script 已通过 Bash syntax check。
- 今日模块决定在此关闭，不进行人为故障测试。

### 今日核心流程

```text
IEI Server
→ systemd fro-watchdog.timer
→ 每约 30 秒
→ Check FRO /dashboard
→ Healthy → failures = 0
→ Failed → failures + 1
→ 3 consecutive failures
→ Restart remoteoffice
→ Check FRO recovery
→ Event Log
```

### Next Session

1. IEI Server Status → connect to real Event Log.
2. Replace Dashboard placeholder IEI events.
3. Add real Server Online / Offline / Reconnected / Restart / Upgrade events.
4. Later consider IEI OS / hardware watchdog.
