排查"categraf 已装/在跑但夜莺机器列表看不到、或显示 unknown / 无指标"的接入失败问题。当用户问"新装的机器为什么没出现"、"机器列表 OS 都是 unknown"、"Helm 装了 3 个采集器只看到 1 个"、"agent 注册不进来"、"装完 categraf 主机没显示"时触发。与 n9e-host-host-health-diagnose **互斥**：那个处理"曾经接入过、现在失联"，本 skill 处理"压根没接入进来"。核心立场：**机器没出现不是一个原因，而是接入链路上某一段断了**。只看 heartbeat.enable 一项就让用户改 categraf，是社区 FAQ 高频翻车点（很多用户改了还是看不到，因为问题在 omit_hostname / ident shell / TLS / token / edge redis / 多集群路由）。
