| 实例 | 问题 | 详情 |
|---|---|---|
| t591-dealhub | 复制中断 replication_stopped | IO=False, SQL=True（IO 线程已停止，中继日志仍在回放，秒级延迟显示 0） |
建议：matched_alias: staging/t591-dealhub → connect 后 SHOW SLAVE STATUS 确认 Last_IO_Error，排查主库连通性/账号权限后 START SLAVE IO_THREAD（本巡检只读未操作）。
无（alerts 中无 warning；按阈值扫描 data 复核：延迟均 0s、连接使用率最高 16.1%、slow_qps 最高 0.01，均未达阈值）。
