不会构建镜像。 - -### 正式版发布 - -推送匹配项目版本的 `vMAJOR.MINOR.PATCH` tag 会触发完整跨平台构建、正式 OCI 镜像推送和 Gitea Release。正式镜像使用 `registry.oeo.one/monitor/` 路径;Agent、Probe 提供 amd64 与 arm64 多架构标签,稳定版本更新正式仓库自己的 `latest`。这与 `monitor-dev/` 的 dev `latest` 相互独立。 - -Agent 和 Probe 镜像分别发布为 `registry.oeo.one/monitor/monitor-agent:` 与 `registry.oeo.one/monitor/monitor-probe:`,包含 amd64、arm64 多架构索引;也可指定 `:-amd64` 或

需使用宿主网络以保持节点端口和测量流量行为,并按需添加 `NET_RAW` 能力以执行 ICMP 测量: - -```sh -docker run -d --name monitor-agent --restart unless-stopped --network host \ - --cap-add NET_RAW -v "$PWD/agent-config:/etc/monitor" \ -

OpenSSL 自检; -- systemd(Debian 12):两个服务 active,Agent 只有 `CAP_NET_RAW`、Probe 没有 capability,`NoNewPrivs`、seccomp 生效,Agent 无法写 `/etc/monitor`,没有重启和错误日志。 - -没有验证的:arm64 构建、真正的 OpenWrt 设备(有 procd 和真实的内存/闪存限制)、跨公网的真实线路。 - -实测常驻内存(RSS,回环,默认模板,稳定后):Linux 上 Probe 约 21 MB、Agent 约 23 MB;Windows 上约 22 MB、25 MB。 - -### 跨机器的真实链路(Windows Probe → WSL2 里的 Agent 和 Backend) - -`scripts/smoke-wsl.py` 用 Windows 上的 NativeAOT Probe 连 WSL2 里的 Agent(真实的虚拟网络,两端的单调时钟原点相差约 38 小时),并用 `tc netem` 在 WSL 里注入故障。结果(Probe 的 RTT 基线约 0.4 ms): - -| 注入 | 期望 | 实测 | -| --- | --- | --- | -| Agent→Probe 方向 10% 丢包、30 ms ± 5 ms 延迟(egress netem,只匹配 7443/7444) | 丢包在下行,下行抖动变大 | `loss.down` 8.2%、`loss.up` 0;`jitter.down.p95` 8.7 ms、`jitter.up.p95` 0.18 ms;RTT +31 ms;TCP:`tcp.rtt.p99` 1.2 s、`tcp.slow` 28.8%、`tcp.retrans` 5.9%(Agent 一侧内核计数) | -| Probe→Agent 方向 10% 丢包、20 ms ± 3 ms 延迟(ingress + ifb) | 丢包在上行 | `loss.up` 9.4%、`loss.down` 0;`jitter.up.p95` 5.2 ms、`jitter.down.p95` 0 | -| 8 秒黑洞(tc ingress drop 7443/7444) | UDP 连续丢包 ~80 个;TCP 不丢包,只有几秒的长尾 | UDP 最长连续丢包 80(10 Hz × 8 s);`tcp.rtt.max` 9.5 s、`tcp.stall_max` 9.6 s | -| `hy2_ladder`(10/25/50/100 Mbit/s) | 无丢包 | `train.loss` 0.006%、`train.jitter.p95` 0.64 ms、可持续 100 Mbit/s | -| 杀掉 Agent / 杀掉 Probe 再启动 | 自动恢复 | Agent 重启后 2.1 s 恢复在线并重新连上 Probe;Probe 重启后 0.5 s 重新连上 | - -验证中发现并修掉的两个问题: - -- **Probe 重启后,Agent 沿用了上一个会话的记录**:Probe 重启之后序号从 0 开始,Agent 里同一个序号的旧 t2/t3 还在,于是真正的上行丢失被算成了下行丢失(黑洞测试里 `loss.up` 0、`loss.down` 7.4%)。现在新的 Probe 会话开始时 Agent 清空所有流的记录。 -- **TCP 回显的几秒中断被记成丢包**:Probe 像 UDP 那样等 2 秒就把没有回复的行交出去,TCP 随后才到的回复没有行可以回填,最严重的长尾反而在 RTT 里看不到(黑洞期间 `tcp.rtt.max` 只有 4 ms)。现在 TCP 的行等回复,30 秒仍然没有才当作连接已断(t4 缺失)。 - -没有覆盖的:Windows 上的 Agent(需要给 Windows 防火墙加入站规则)、NAT 重绑定。跨公网的线路见下一节。 - -### 跨公网的真实线路(广东移动家宽 → 日本 IIJ 的 VPS) - -2026-10-03 在一条真实线路上试跑过:家宽机器(Debian 13,用户态运行,没有公网 IPv4 入站)跑 Probe 和 Backend,VPS(Debian 12,1 核 470 MB,上面本来就跑着 xray、hysteria2、caddy 等服务)跑 Agent。 - -```text -浏览器 / 本机前端 ──► https://<公网域名> ──隧道(Cloudflare Tunnel 之类)──► 家宽机器: Backend (:29181) - 家宽机器: Probe ──WSS 到 https://<公网域名>──► Backend(身份、Agent 列表) - 家宽机器: Probe ──TCP/UDP 7443、TCP 7444──► VPS: Agent - VPS: Agent ──WSS 到 https://<公网域名>──► Backend -``` - -做法和要点: - -- **Backend 通过隧道暴露**:隧道把一个公网域名转到家宽机器的 `29181`;Backend 监听 `http://0.0.0.0:29181`(只写一个监听地址,同时写 `0.0.0.0` 和 `[::]` 会报地址已被占用),家宽路由器的防火墙不放行这个端口,公网只能经隧道进来。Agent 用 `fleet-enroll --server https://<公网域名>` 注册,之后用 WSS 连回 Backend。 -- **经隧道注册之后,检查 Agent 的 `public_host`**:Backend 看到的来源地址是隧道的出口,不是 VPS 的地址,要改成 VPS 的真实地址,Probe 才连得上。 -- **Probe 直连面板**:`probe.json` 里的 `server` 就是面板地址(取自 `Monitor__PublicUrl`,没配就用创建它时的请求地址),Probe 用它连面板,Agent 列表由面板下发;先注册还是先创建 Probe 都可以。 -- **小 VPS 把 `limits.max_total_mbps` 调低**(试跑时用 100);Agent 常驻约 23 MB,VPS 上原有的服务不受影响,结束后删除 `/opt/…`、停掉进程即可,没有留下任何东西。 -- 家宽的 IPv6 前缀会在路由器重新拨号(比如停电)后变化,SSH 地址要跟着换;面板走隧道的域名,不受影响。 -- 本地电脑没有直连 VPS 的路径时,用家宽机器当跳板(`SSH_ASKPASS` + `SSH_ASKPASS_REQUIRE=force`,密码放环境变量,不写进文件)。 - -**常驻(开机自启)**: - -- 家宽机器(没有 root 时):`~/.config/systemd/user/monitor-backend.service` 和 `monitor-probe.service`,`EnvironmentFile` 指向放配置的 `backend.env`,`Restart=always`,`systemctl --user enable --now …`,再用 `sudo loginctl enable-linger <用户>` 让它们不登录也能起来。Probe 的命令行是 `monitor-probe --config `(默认路径是 `/etc/monitor/probe.json`)。 -- VPS:`/etc/systemd/system/monitor-agent.service`,`Restart=always`,加 `NoNewPrivileges`、`ProtectSystem=strict`、`ReadWritePaths=/opt/monitor`、`ProtectHome`、`PrivateTmp`。这是不走安装脚本的手动方式;正式安装用上面的 `packaging/systemd`。 -- 日志进 journal:`journalctl -u monitor-agent`、`journalctl --user -u monitor-probe`。重启 Backend 用 `systemctl` 而不是手动再起一个进程,否则会端口冲突。 - -**国家和运营商**:Backend 用 Probe、Agent 的来源地址向 IP 归属服务查一次,展示在国旗和运营商图标上(`Monitor__GeoLookupUrl`,缺省 `https://ip.007995.xyz`;留空就不查;这个服务只供公益使用,署名和使用条款由部署的人自己遵守)。Probe、Agent 自己不访问外部服务,所以客户的防火墙审计里不会多出出站连接;Backend 发出去的只有公网 IP(内网地址不发)。 - -**从别处看这个面板**:本机跑前端,在页面里把数据源指向这个域名,用 API 令牌访问,Backend 设 `Monitor__CorsOrigins` 放行前端的来源(见 [web/README.md](../web/README.md))。 - -实测(Probe 在广东移动家宽,Agent 在日本 IIJ): - -| 项目 | 结果 | -| --- | --- | -| 延迟 p50 / p95 / p99 | 107 / 107 / 114 ms | -| 丢包 | 上行 0%,下行 8.1%(`hy2_ladder` 在 10、25、50、100 Mbit/s 四档下的丢包都是 8~10%,与速率无关:随机丢包,不是限速) | -| 抖动 p95(上 / 下) | 0.9 / 5.2 ms | -| TCP | 重传 1.9%(批量传输时 5.8%),RTT 最大 412 ms | -| `reality_session` | 建连成功率 100%,TCP 建连 p95

-这次试跑发现并修掉的问题:`hy2_ladder` 的阶梯按「块」而不是按「阶段」计算,真实的 Probe 把一个阶段切成几块,4 个阶段出了 7 步(模拟数据不切块,所以之前的测试没有发现);现在同一阶段的块先合并。 +# 部署 + +节点(Agent、Probe)是单个 NativeAOT 可执行文件,没有运行时依赖,只需要系统的 OpenSSL

Agent 清空所有流的记录。 +- **TCP 回显的几秒中断被记成丢包**:Probe 像 UDP 那样等 2 秒就把没有回复的行交出去,TCP 随后才到的回复没有行可以回填,最严重的长尾反而在 RTT 里看不到(黑洞期间 `tcp.rtt.max` 只有 4 ms)。现在 TCP 的行等回复,30 秒仍然没有才当作连接已断(t4 缺失)。 + +没有覆盖的:Windows 上的

xray、hysteria2、caddy 等服务)跑 Agent。 + +```text +浏览器 / 本机前端 ──► https://<公网域名> ──隧道(Cloudflare Tunnel 之类)──► 家宽机器: Backend (:29181) + 家宽机器: Probe ──WSS 到 https://<公网域名>──► Backend(身份、Agent 列表) + 家宽机器: Probe ──TCP/UDP 7443、TCP 7444──► VPS: Agent + VPS: Agent ──WSS 到 https://<公网域名>──► Backend +``` + +做法和要点: + +- **Backend 通过隧道暴露**:隧道把一个公网域名转到家宽机器的 `29181`;Backend 监听 `http://0.0.0.0:29181`(只写一个监听地址,同时写 `0.0.0.0` 和 `[::]` 会报地址已被占用),家宽路由器的防火墙不放行这个端口,公网只能经隧道进来。Agent 用 `fleet-enroll --server https://<公网域名>` 注册,之后用 WSS 连回 Backend。 +- **经隧道注册之后,检查 Agent 的 `public_host`**:Backend 看到的来源地址是隧道的出口,不是 VPS 的地址,要改成 VPS 的真实地址,Probe 才连得上。 +- **Probe 直连面板**:`probe.json` 里的 `server` 就是面板地址(取自 `Monitor__PublicUrl`,没配就用创建它时的请求地址),Probe 用它连面板,Agent 列表由面板下发;先注册还是先创建 Probe 都可以。 +- **小 VPS 把 `limits.max_total_mbps` 调低**(试跑时用 100);Agent 常驻约 23 MB,VPS 上原有的服务不受影响,结束后删除 `/opt/…`、停掉进程即可,没有留下任何东西。 +- 家宽的 IPv6 前缀会在路由器重新拨号(比如停电)后变化,SSH 地址要跟着换;面板走隧道的域名,不受影响。 +- 本地电脑没有直连 VPS 的路径时,用家宽机器当跳板(`SSH_ASKPASS` + `SSH_ASKPASS_REQUIRE=force`,密码放环境变量,不写进文件)。 + +**常驻(开机自启)**: + +- 家宽机器(没有 root 时):`~/.config/systemd/user/monitor-backend.service` 和 `monitor-probe.service`,`EnvironmentFile` 指向放配置的 `backend.env`,`Restart=always`,`systemctl --user enable --now …`,再用 `sudo loginctl enable-linger <用户>` 让它们不登录也能起来。Probe 的命令行是 `monitor-probe --config `(默认路径是 `/etc/monitor/probe.json`)。 +- VPS:`/etc/systemd/system/monitor-agent.service`,`Restart=always`,加 `NoNewPrivileges`、`ProtectSystem=strict`、`ReadWritePaths=/opt/monitor`、`ProtectHome`、`PrivateTmp`。这是不走安装脚本的手动方式;正式安装用上面的 `packaging/systemd`。 +- 日志进 journal:`journalctl -u monitor-agent`、`journalctl --user -u monitor-probe`。重启 Backend 用 `systemctl` 而不是手动再起一个进程,否则会端口冲突。 + +**国家和运营商**:Backend 用 Probe、Agent 的来源地址向 IP 归属服务查一次,展示在国旗和运营商图标上(`Monitor__GeoLookupUrl`,缺省 `https://ip.007995.xyz`;留空就不查;这个服务只供公益使用,署名和使用条款由部署的人自己遵守)。Probe、Agent 自己不访问外部服务,所以客户的防火墙审计里不会多出出站连接;Backend 发出去的只有公网 IP(内网地址不发)。 + +**从别处看这个面板**:本机跑前端,在页面里把数据源指向这个域名,用 API 令牌访问,Backend 设 `Monitor__CorsOrigins` 放行前端的来源(见 [web/README.md](../web/README.md))。 + +实测(Probe 在广东移动家宽,Agent 在日本 IIJ): + +| 项目 | 结果 | +| --- | --- | +| 延迟 p50 / p95 / p99 | 107 / 107 / 114 ms | +| 丢包 | 上行 0%,下行
