Struct RuntimeMetricsOpts 

pub struct RuntimeMetricsOpts {
    pub poll_time_histogram: bool,
    pub poll_time_histogram_scale: Option<RuntimeMetricsPollTimeHistogramScale>,
    pub poll_time_histogram_resolution: Option<Duration>,
    pub poll_time_histogram_buckets: Option<usize>,
}

Configuration options for runtime metrics collection.

Fields

poll_time_histogram: bool

Enable Tokio’s poll-time histogram on the runtime.

This must be configured before the runtime is built. Enabling it adds two timestamp reads to every task poll.

poll_time_histogram_scale: Option<RuntimeMetricsPollTimeHistogramScale>

Histogram bucket scale for Tokio’s poll-time histogram.

poll_time_histogram_resolution: Option<Duration>

Width of the first histogram bucket.

poll_time_histogram_buckets: Option<usize>

Number of histogram buckets. Memory usage scales with runtimes × workers × buckets.
