Struct TunnelClosedJson 

pub struct TunnelClosedJson {
    pub ok: bool,
    pub event: String,
    pub vps: String,
    pub reason: TunnelCloseReason,
    pub bind: String,
    pub local_port: u16,
    pub forwards_served: u64,
    pub capacity_waits: u64,
    pub duration_ms: u64,
    pub mode: String,
}

tunnel --json shutdown event.

G-TUN-R07: the tunnel used to emit tunnel_listening and then fall silent until death, so three very different endings shared exit 0 — deadline reached, signal received, and a fatal accept error that broke the loop early. The last case was the worst: because bound was already true, the timeout wrapper returned Ok(()) and the process reported success even though it had stopped accepting connections seconds into a five-minute deadline. Those are now distinguishable.

Fields

ok: bool

true when the tunnel served its full lifetime.

event: String

Discriminator: "tunnel_closed".

vps: String

VPS name.

reason: TunnelCloseReason

Why the tunnel stopped.

bind: String

Effective local bind address.

local_port: u16

Local listen port that was served.

forwards_served: u64

Connections accepted and forwarded during the tunnel’s lifetime.

G-TUN-R11: answers the most basic diagnostic question — did anything ever connect? A tunnel that bound correctly but was never used produced output identical to one that served five hundred connections.

capacity_waits: u64

Times a new connection had to wait for a concurrency permit.

G-TUN-R12: saturation was previously invisible, so the symptom was rising latency with no stated cause and the operator could hunt the network instead.

duration_ms: u64

Wall-clock lifetime in milliseconds.

mode: String

Which tunnel mode was serving (mirrors TunnelListeningJson::mode).
