Expand description

Builder for PrometheusObserver.

Implementations§

Source§

impl PrometheusBuilder

Source

pub fn new() -> PrometheusBuilder

Creates a new PrometheusBuilder with default values.

Source

pub fn set_quantiles(self, quantiles: &[f64]) -> PrometheusBuilder

Sets the quantiles to use when rendering histograms.

Quantiles represent a scale of 0 to 1, where percentiles represent a scale of 1 to 100, so a quantile of 0.99 is the 99th percentile, and a quantile of 0.99 is the 99.9th percentile.

By default, the quantiles will be set to: 0.0, 0.5, 0.9, 0.95, 0.99, 0.999, and 1.0.

Source

pub fn set_buckets(self, values: &[u64]) -> PrometheusBuilder

Sets the buckets to use when rendering summaries.

Buckets values represent the higher bound of each buckets.

This option changes the observer’s output of histogram-type metric into summaries.

Source

pub fn set_buckets_for_metric( self, name: &str, values: &[u64], ) -> PrometheusBuilder

Sets the buckets for a specific metric, overidding the default.

Matches the metric name’s suffix, the longest match will be used.

This option changes the observer’s output of histogram-type metric into summaries. It only affects matching metrics if set_buckets was not used.
