Struct ServerMetrics 

#[non_exhaustive]
pub struct ServerMetrics {
    pub workers: Vec<WorkerMetrics>,
    pub listeners: Vec<ListenerMetrics>,
    pub accept_pauses: u64,
    pub accept_paused_duration: Duration,
    pub accept_backlog: usize,
    pub incoming_cpu_hits: u64,
    pub incoming_cpu_misses: u64,
    pub rescheduled: u64,
}

Snapshot of server metrics.

Counters and durations are totals since the server started. Rates over an interval are computed from the deltas of two snapshots.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

workers: Vec<WorkerMetrics>

Per-worker metrics, indexed by worker id.

listeners: Vec<ListenerMetrics>

Per-listener metrics, empty for servers without listeners.

accept_pauses: u64

Number of times the accept loop stopped accepting connections, because no worker was available or the server was paused.

accept_paused_duration: Duration

Total time the accept loop did not accept connections, including the current pause.

accept_backlog: usize

Number of accepted connections waiting in the accept loop for an available worker.

incoming_cpu_hits: u64

Number of items sent to the worker on their incoming CPU, see LoadBalancing::IncomingCpu.

incoming_cpu_misses: u64

Number of items with a known incoming CPU that were sent to another worker, because no worker is placed on that CPU or its worker was busier than other workers.

rescheduled: u64

Number of items taken from the queue of a failed, unavailable or blocked worker and sent to another worker.
