Previous agent logging suffered from noisy repetitive '--- status ---'
dumps to stdout every 15 seconds, intermingled with raw println! event lines
and lacking structured log levels. Furthermore, the status report only
inspected WireguardPlugin tunnels; when tcp-tls took precedence and established
a link, the status falsely showed wg-quic as '0/1 tunnels established, waiting
for a data link' without mentioning the active tcp-tls link.
Key changes:
- Adopt compact, clean tracing output: initialize tracing_subscriber with
.with_target(false).compact() and default filter
'info,iroh=warn,quinn=warn,rustls=warn,boringtun=warn,mainline=warn'
to keep standard agent events at INFO while silencing noisy internals.
- Route agent events through structured tracing (log_event):
emit INFO for peer connect/disconnect, data link up/down, and network
activation; WARN for rejections and plugin errors; DEBUG for dials.
- Disable periodic status dump by default (set status_interval default to 0),
and re-route periodic ticks to tracing::debug! (log_status_summary).
- Add active_peers() to GenericTunnelPlugin and update build_report to
include active tcp-tls tunnels in OverlayReport alongside WireGuard peers.
- Display enabled protocol priority on agent startup.
Validation on Linux:
- cargo fmt --all -- --check passed.
- cargo clippy --locked --workspace --all-targets -- -D warnings passed.
- cargo test --locked --workspace --all-targets passed (347 tests passed).
