+
+2026-10-15 生产调优结论：统一 4 秒读取 CPU、内存、温度及网络速率。曾试 2 秒，但这台 DSM 的 utilization 实际采样时间通常每 4 秒更新，连续细粒度观察 CPU 时间为 7853/7857/7861/7865 等相差 4 秒的样本；不能把两次相同样本当成更快采样。只读接口测量 System.info 约 0.05–0.07 秒、Utilization.get 约 1.03–1.09 秒，请求耗时与真实样本周期不同。
+
+最终 40 秒连续观测：两设备各 10 个独立实时样本、10 个网络样本，中位间隔均 4 秒；无离线或缺失采集组，缓存 API 最大耗时 0.032 秒（这是 Console 缓存读取，不是 DSM 接口耗时）。Pi 本地 CPU 等继续 1 秒，网络配置已从 5 秒改为 2 秒；Console 每 4 秒读取，覆盖更快缓存。NAS 网络配置 60 秒、存储 24 小时保持。

+# 磁盘手动扫描（2026-10-15）
+
+后续显示层已升级为 Console v2.7.0 / Ubuntu 插件 v1.5.0 / Raspberry Pi 插件 v1.6.0 / Synology 插件 v1.9.0：默认原样使用设备返回顺序，取消 NAS 特殊倒序和优先级。显示名称、同组排序、隐藏统一保存到 Console，首页与配置共用，支持恢复默认顺序。设备已有名称/隐藏定义保留为默认上报值；本篇后文“名称保存在 Agent”等描述为当时的设备定义行为，不代表最新 Console 显示偏好的存储位置。最新验收见相邻 pigway-web-manager/docs/STORAGE-PRESENTATION-v2.7.0-2026-10-15.md；所有实际扫描行为保持手动。
+
+## 已上线状态
+
+Ubuntu Agent v1.3.1 / Console 插件 v1.4.1，Raspberry Pi Agent v3.11.1 / 插件 v1.5.1，Synology 插件 v1.8.1 已上线。两台 Agent 各识别两个实际分区，监控/API 服务 active，循环错误 0。
+
+三种设备在线；中英文及 1440/820/390 三种屏宽的生产界面通过。设备名称、顺序和隐藏设置保留。Console 重启、页面加载及浏览器验收前后，NAS storage_observed_at 未改变，本次没有额外扫描 NAS 硬盘。尚未插入新物理磁盘，也未进行休眠/唤醒实测。
+
+用户最终确认“三种设备都手动发现新增磁盘”。此前自动发现与 NAS 每 5 分钟扫描的候选方案已替换。
+
+## 使用
+
+Ubuntu、树莓派：Console → 系统配置 → 选择设备 → 磁盘设置 → 扫描磁盘。扫描后重新打开该页查看新磁盘，概览随正常轮询更新。名称和隐藏设置保存到 Agent，隐藏不停止历史采集。
+
+NAS：与其他设备一样在配置 → 磁盘设置中点击“扫描磁盘”，首页只展示数据。磁盘清单、容量、温度、健康状态仅在手动扫描时更新；页面保留采集时间。CPU、内存和网络等快速采集继续工作。已有卷别名仍由 Console 保存。
+
+v1.4.1 / v1.5.1 / v1.8.1 统一配置页扫描入口，保存按钮上方保留 20px 间距，扫描与保存反馈分别显示。按用户最终要求，NAS 每个机箱内硬盘采用 DSM 返回顺序反转；存储空间同样反转，主空间和 SSD 空间优先。生产三种屏宽、中英文已验证入口、间距、倒序及优先级；NAS 存储采集时间未改变。前两次发布因验收脚本固定计入网络卡片位置而自动回退，修正为直接验证存储卡片后通过。
+
+扫描有 60 秒冷却，NAS 在途请求合并。页面加载、普通刷新、定时轮询和重启不会重新枚举磁盘。部署时执行过一次明确的初始扫描以保存现有 Agent 磁盘清单。
+
+## 实现与边界
+
+认证 PUT /api/v1/storage/scan 调用 lsblk，读取宿主机挂载点，将块设备清单保存到对应配置旁的 .storage.json（0600）。监控服务只读取清单；已知磁盘挂载和容量每 30 秒更新，新增磁盘必须手动扫描。根分区原有指标和告警保留兼容。
+
+UUID 优先作为标识，其次为设备序列号和分区编号，再退回路径并标记 stable_identity=false。展示可用叶设备，去除重复挂载及 loop/swap 等伪设备。未挂载设备不伪造使用率。配置过的条目在后续扫描未发现时保留为断开；扫描失败保留原清单。
+
+不执行挂载、格式化、分区或 SMART 指令。本次没有增加每磁盘断开/容量告警。
+
+Agent 手工配置使用 status.system.storage_inventory[].id 的 32 位十六进制 key：
+
+```ini
+[storage_names]
+0123456789abcdef0123456789abcdef = 媒体盘
+[storage_visible]
+0123456789abcdef0123456789abcdef = true
+```
+
+NAS 普通 collect 不再调度存储任务，只有 device.refresh(group=storage) 触发慢查询。重启复用上次摘要；过旧健康数据标为未确认，不确认旧告警恢复。只展示 DSM hdd_info / vol_info 上报的硬盘、扩展柜和卷，未验证任意 USB 外接盘是否均由接口提供。
+
+## 验证和备份
+
+两种 Agent 覆盖挂载点转义、bind 去重、伪设备、未挂载状态、UUID 稳定性、百分号名称、隐藏设置、手动发现和重启后禁止自动枚举。两种插件的中英文/三屏宽测试覆盖 0% 使用率、名称转义、隐藏恢复和显式扫描；打开设置不会扫描。NAS 15 项 Python 回归及六种浏览器布局通过。
