Implementations§

Source§

impl MetricsRegistry

Source

pub fn new() -> Self

Creates a new metrics registry.

Source

pub fn register<M>(&self, opts: MakeCollectorOpts) -> M
where M: MakeCollector,

Register a metric defined with the metric macro.

Source

pub fn register_computed_gauge<F, P>( &self, opts: MakeCollectorOpts, f: F, ) -> ComputedGenericGauge<P>
where F: Fn() -> P::T + Send + Sync + 'static, P: Atomic + 'static,

Registers a gauge whose value is computed when observed.

Source

pub fn register_collector<C: 'static + Collector>(&self, collector: C)

Register a pre-defined prometheus collector.

Source

pub fn register_postprocessor<F>(&self, f: F)
where F: FnMut(&mut Vec<MetricFamily>) + Send + Sync + 'static,

Registers a metric postprocessor.

Postprocessors are invoked on every call to MetricsRegistry::gather in the order that they are registered.

Source

pub fn gather(&self) -> Vec<MetricFamily>

Gather all the metrics from the metrics registry for reporting.

This function invokes the postprocessors on all gathered metrics (see MetricsRegistry::register_postprocessor) in the order the postprocessors were registered.

See also prometheus::Registry::gather.
