Total traffic at a glance
Read aggregate VPS interface counters collected every 5 minutes and display used traffic against the monthly quota.
VPN_ZZ · TRAFFIC OVERVIEW
VPN_ZZ traffic and health at a glance.
This dashboard is designed to show aggregate VPN_ZZ traffic, monthly quota posture, sing-box health, and configured device status without exposing VPN credentials or per-device secrets.
OVERVIEW SURFACE
What the VPN_ZZ overview shows
The first version is intentionally simple: total traffic, monthly quota posture, service health, and device configuration status. Exact per-device traffic is deliberately deferred.
Service health
Show whether sing-box is active and whether the 443 VPN boundary is still present without changing the VPN service.
Device configuration status
Show MacBook, iPhone, iPhone 2, iPhone 3, iPhone 4, and Android 1 as configured, with verification status only, without displaying credentials or QR codes.
Privacy boundary
Keep UUIDs, VLESS URIs, sensitive transport keys, raw configs, and per-device accounting out of this overview.
DATA FLOW
Collector → status API → dashboard
A lightweight timer on the Tencent Cloud VPS samples local counters once per minute. The status API reads the local SQLite summary and the dashboard renders only the aggregate, privacy-safe view.

BOUNDARY CHECK
What this overview deliberately does not do
The overview adds visibility without expanding the VPN attack surface. It does not modify sing-box, expose credentials, or open a new public port.
- Reads only local aggregate network counters and service state
- Keeps UUIDs, VLESS URIs, sensitive transport keys, QR codes, and raw configs out
- Leaves sing-box config, VPS 443, DNS, Tunnel, and firewall unchanged
- Exact per-device traffic remains disabled by design
- Any future per-device stats requires a separate staging and authorization gate
