Module opentelemetry::exporter::metrics::prometheus

OpenTelemetry Prometheus Exporter

This exporter currently delegates to the Prometheus library library which implements the Prometheus API.

Structs

CounterHandle	Prometheus CounterHandle
GaugeHandle	Prometheus GaugeHandle
Histogram	A Metric counts individual observations from an event or sample stream in configurable buckets. Similar to a summary, it also provides a sum of observations and an observation count.
HistogramOpts	A struct that bundles the options for creating a Histogram metric. It is mandatory to set Name and Help to a non-empty string. All other fields are optional and can safely be left at their zero value.
IntCounterHandle	Prometheus IntCounterHandle
IntGaugeHandle	Prometheus IntGaugeHandle
IntMeasure	Prometheus Histograms do not have i64 variant, IntMeasure will convert i64 to float when it records values.
IntMeasureHandle	Prometheus IntMeasureHandle
MeasureHandle	Prometheus MeasureHandle
Opts	A struct that bundles the options for creating most Metric types.
Registry	A struct for registering Prometheus collectors, collecting their metrics, and gathering them into MetricFamilies for exposition.
TextEncoder	An implementation of an Encoder that converts a MetricFamily proto message into text format.

Traits

Encoder

An interface for encoding metric families into an underlying wire protocol.

Functions

default_registry	Default registry (global static).
gather	Return all MetricFamily of DEFAULT_REGISTRY.

Type Definitions

Counter	A Metric represents a single numerical value that only ever goes up.
CounterVec	A Collector that bundles a set of Counters 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 HTTP requests, partitioned by response code and method).
Gauge	A Metric represents a single numerical value that can arbitrarily go up and down.
GaugeVec	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).
HistogramVec	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).
IntCounter	The integer version of Counter. Provides better performance if metric values are all integers.
IntCounterVec	The integer version of CounterVec. Provides better performance if metric values are all integers.
IntGauge	The integer version of Gauge. Provides better performance if metric values are all integers.
IntGaugeVec	The integer version of GaugeVec. Provides better performance if metric values are all integers.
