Type Definition opentelemetry::exporter::metrics::prometheus::HistogramVec

type HistogramVec = MetricVec<HistogramVecBuilder>;

A Collector that bundles a set of Histograms that all share the same Desc, but have different values for their variable labels. This is used if you want to count the same thing partitioned by various dimensions (e.g. HTTP request latencies, partitioned by status code and method).

Trait Implementations

impl Instrument<HashMap<Cow<'static, str>, Cow<'static, str>, RandomState>> for HistogramVec

fn record_one(&self, value: MeasurementValue, label_set: &LabelSet)

record a single measure measurement value

impl Measure<f64, HashMap<Cow<'static, str>, Cow<'static, str>, RandomState>> for HistogramVec

type Handle = MeasureHandle

The handle type for the implementing Measure.

fn measurement(&self, value: f64) -> Measurement<LabelSet>

Creates a Measurement object to be used by a Meter when batch recording.

fn acquire_handle(&self, labels: &LabelSet) -> Self::Handle

Creates a handle for this instrument.

fn record(&self, value: T, label_set: &LS)

Records the passed value to the value of the measure. The labels should contain the keys and values for each key specified in the LabelSet.
