The subscription port answered every request with signed JSON: one probe
told a scanner what it had found, and the public key from any sen:// link
pinned the exact server. It now speaks the protocol only to those who prove
a secret — peek and register with the link's master secret, everything else
with a valid device signature — and gives Go's plain "404 page not found"
to the rest. A deleted device still gets its 410, but only when the request
is signed with its key, kept in the new revoked_devices table. The migration
freeze answers only proven clients too.
Self-signed certs for the subscription (SUB_TLS=on) and the node hub got
fixed names (sen, awg-node); new ones get a random host-like name. Clients
and nodes pin the key, so existing certs keep working.
The panel could already issue a metrics-only token, but nothing in the UI
used it. The Monitor tab gets an "External Prometheus" card: issue, reissue
and revoke the token, with a ready prometheus.yml fragment whose address is
taken from the page, so it carries the secret path or the nginx subfolder.

A panel without VPN (e.g. after the move) can use a Prometheus that lives on
a node, such as the one with history left on the old server (node #0). Both
directions go through the agent's WSS: the node's Prometheus scrapes
127.0.0.1:AGENT_METRICS_PORT/metrics, the agent checks its token and asks
core (metrics → metrics_res, the same exposition as /metrics, at most once
per 5 s per connection); the monitor tab reads it back through the agent,
which forwards only GET /-/ready and /api/v1/query[_range]. The panel finds
it by itself (local first, then the lowest-id node), and the install/remove
buttons work on a panel without VPN. `monitor install` on a node without its
own panel picks AGENT_METRICS_PORT, writes it to cli.env and restarts the
agent; on the old server it keeps the collected data.
The panel works behind nginx in a subfolder: relative asset and API paths,
relative directory redirects, and the client address from X-Forwarded-For /
X-Real-IP only from trusted proxies (loopback, TRUST_PROXY).
migrate import opens the moved SUB_PORT/NODE_PORT in UFW when it is active.
- ranges 7d (30 min step) and 30d (2 h step); Prometheus keeps 31d
- rate() window is at least the step, so long views show averages
instead of a 2-minute sample; "now" values still use a 2m window
- overview returns used_down/used_up: increase() of the interface
counters over the whole range
- tiles merged: traffic (with volume for the period), devices, load
Baseline TypeScript version before the Go rewrite: CAKE fair sharing with
automatic deprioritisation of heavy devices, per-key priority, /metrics with
a metrics token, the built-in Prometheus install/remove, the Monitor tab,
grouped sidebar tabs and the dead-peer audit.
