    pub peer_id: String,
    pub active_connections: u32,

Expand description

Per-peer load tracking information.

Fields§

§peer_id: String

Unique peer identifier.

§active_connections: u32

Number of currently in-flight requests.

§weight: u32

Routing weight; higher values attract more requests.

§avg_latency_ms: f64

Exponentially-weighted moving average of latency (ms), alpha = 0.2.

§total_requests: u64

Total requests ever dispatched to this peer.

§failed_requests: u64

Total failed requests for this peer.

Implementations§

Source §

impl PeerLoad

Source

pub fn failure_rate(&self) -> f64

Fraction of requests that have failed; returns 0.0 when no requests have been dispatched yet.

Source

pub fn is_healthy(&self) -> bool

A peer is healthy when its failure rate is below 50 % and it has fewer than 1 000 active connections.
