Enum metrics_exporter_prometheus::Distribution

pub enum Distribution {
    Histogram(Histogram),
    Summary(Summary, Arc<Vec<Quantile>>, f64),
}

Distribution type.

Variants

Histogram(Histogram)

A Prometheus histogram.

Exposes “bucketed” values to Prometheus, counting the number of samples below a given threshold i.e. 100 requests faster than 20ms, 1000 requests faster than 50ms, etc.

Summary(Summary, Arc<Vec<Quantile>>, f64)

A Prometheus summary.

Computes and exposes value quantiles directly to Prometheus i.e. 50% of requests were faster than 200ms, and 99% of requests were faster than 1000ms, etc.

Implementations

impl Distribution

pub fn new_histogram(buckets: &[f64]) -> Distribution

Creates a histogram distribution.

pub fn new_summary(quantiles: Arc<Vec<Quantile>>) -> Distribution

Creates a summary distribution.

pub fn record_samples(&mut self, samples: &[f64])

Records the given samples in the current distribution.

Trait Implementations

impl Clone for Distribution

fn clone(&self) -> Distribution

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
