节点 sing-box 编入 with_v2ray_api 后,每个 dp_uuid 有独立计数器
user>>>{dp_uuid}>>>traffic>>>uplink|downlink。agent 用 QueryStats(reset=true)
取窗口 delta,按用户精确上报(替代旧 clash 节点总量分摊:单用户准、多用户近似)。
- render.go: experimental.v2ray_api(loopback :19091)+ stats.users 列全部 dp_uuid
- v2rayapi/: vendor sing-box stats.pb.go(消息)+ 手写 client(用 v2ray 规范
ServiceName 路径,绕开生成代码的 experimental.v2rayapi.* 误名)
- usage_v2ray.go: V2RayUsageSource,uplink/downlink 天然用户视角(无需 swap)
- agent.UseV2RayUsage() 取代 UseClashUsage();clash_api 保留作本地调试
节点需部署带 with_v2ray_api 的 sing-box(已编好 linux/amd64 二进制)。
