Struct RuntimeMetrics 

#[non_exhaustive]
pub struct RuntimeMetrics {
    pub busy_duration: Option<Duration>,
    pub polls: Option<u64>,
    pub polls_again: Option<u64>,
    pub self_wakes: Option<u64>,
    pub poll_histogram: Option<Histogram>,
    pub current_turn: Option<Duration>,
    pub current_task: Option<&'static Location<'static>>,
    pub latency: Option<LatencyMetrics>,
}

Runtime statistics of a worker.

Counters, durations and histograms are totals over all runtimes the worker slot ran on, a restarted worker continues the totals of the worker it replaces. Values a runtime backend does not provide are None.

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.

busy_duration: Option<Duration>

Total time the runtime was busy running tasks.

The busy_duration delta divided by the elapsed time is the worker’s utilization. On tokio it is available only for current-thread runtimes.

polls: Option<u64>

Number of runtime turns that ran scheduled tasks. Not available on tokio.

polls_again: Option<u64>

Number of runtime turns that left scheduled tasks for the next turn. Not available on tokio.

self_wakes: Option<u64>

Number of times a task woke itself while it was polled. Neon only.

poll_histogram: Option<Histogram>

Durations of runtime turns. Not available on tokio.

current_turn: Option<Duration>

How long the current runtime turn has been running, None while the runtime is idle or the backend does not track turns.

current_task: Option<&'static Location<'static>>

Spawn location of the task the runtime is polling now. Neon only.

latency: Option<LatencyMetrics>

Scheduling latency and stalls, None if latency sampling is disabled, see ntex_rt::Builder::latency_interval().

histogram, stalls and stall_duration are totals over all runtimes of the worker slot, the other fields describe the current runtime.
