agents_health_check.py — Tier 1 快速健康检查（Linux/246 部署版）
|
||
============================================================
|
||
每 5 分钟触发。对所有注册服务做检查：PID存活 → 端口监听 → HTTP /health。
|
||
异常时写 TODO 给 self_todo_executor 消费。正常时静默。

部署：Linux crontab: */5 * * * * cd /home/hmo/AgentsMeeting/gateway/scripts && /usr/bin/python3 agents_health_check.py >> ../logs/health_check.log 2>&1
