Type Definition opentelemetry::exporter::metrics::prometheus::GaugeVec

type GaugeVec = MetricVec<GaugeVecBuilder<AtomicF64>>;

A Collector that bundles a set of Gauges 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. number of operations queued, partitioned by user and operation type).

Trait Implementations

impl Gauge<f64, HashMap<Cow<'static, str>, Cow<'static, str>, RandomState>> for GaugeVec

type Handle = GaugeHandle

The handle type for the implementing Gauge.

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 set(&self, value: T, label_set: &LS)

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

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

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

record a single gauge measurement value
