Expand description

Runtime state for a single peer tracked by the balancer.

Fields§

§id: PlbPeerId

Peer identifier.

§capacity: u32

Maximum concurrent requests this peer can handle.

§in_flight: u32

Currently in-flight requests directed at this peer.

§success_count: u64

Cumulative successful responses.

§failure_count: u64

Cumulative failed responses.

§avg_latency_ms: f64

Exponentially weighted moving average of response latency (ms).

§last_used_ts: u64

Unix-ms timestamp of the last request sent to this peer.

§is_healthy: bool

Whether this peer is currently considered healthy.

§weight: f64

Normalised selection weight in [0, 1].

§cooldown_until_ts: u64

Unix-ms timestamp at which the cooldown expires (0 = not in cooldown).
