Module opentelemetry::metrics

This is supported on crate feature metrics only.

OpenTelemetry Metrics API

Modules

noop	No-op OpenTelemetry Metrics Implementation
registry	Metrics Registry API
sdk_api	Metrics SDK API

Structs

AtomicNumber	An atomic version of Number
BatchObserver	An Observer callback that can report observations for multiple instruments.
BatchObserverResult	Passed to a batch observer callback to capture observations for multiple asynchronous instruments.
BoundCounter	BoundCounter is a bound instrument for counters.
BoundUpDownCounter	BoundUpDownCounter is a bound instrument for counters.
BoundValueRecorder	BoundValueRecorder is a bound instrument for recording per-request non-additive values.
Counter	A metric that accumulates values.
CounterBuilder	Configuration for building a counter.
Descriptor	Descriptor contains all the settings that describe an instrument, including its name, metric kind, number kind, and the configurable options.
InstrumentConfig	Config contains some options for metrics of any kind.
Measurement	Measurement is used for reporting a synchronous batch of metric values. Instances of this type should be created by synchronous instruments (e.g., Counter::measurement).
Meter	Meter is the OpenTelemetry metric API, based on a sdk-defined MeterCore implementation and the Meter library name.
Number	Number represents either an integral or a floating point value. It needs to be accompanied with a source of NumberKind that describes the actual type of the value stored within Number.
Observation	Observation is used for reporting an asynchronous batch of metric values. Instances of this type should be created by asynchronous instruments (e.g., ValueObserver::observation).
ObserverResult	Data passed to an observer callback to capture observations for one asynchronous metric instrument.
SumObserver	A metric that captures a precomputed sum of values at a point in time.
SumObserverBuilder	Configuration options for building a SumObserver
Unit	Units denote underlying data units tracked by Meters.
UpDownCounter	A metric instrument that sums non-monotonic values.
UpDownCounterBuilder	Configuration for a new up down counter.
UpDownSumObserver	A metric that captures a precomputed non-monotonic sum of values at a point in time.
UpDownSumObserverBuilder	Configuration options for building a UpDownSumObserver
ValueObserver	A metric that captures a set of values at a point in time.
ValueObserverBuilder	Configuration options for building a ValueObserver
ValueRecorder	ValueRecorder is a metric that records per-request non-additive values.
ValueRecorderBuilder	Initialization configuration for a given ValueRecorder.

Enums

AsyncRunner	Called when collecting async instruments
InstrumentKind	Kinds of OpenTelemetry metric instruments
MetricsError	Errors returned by the metrics API.
NumberKind	A descriptor for the encoded data type of a Number

Traits

MeterProvider

Returns named meter instances

Type Definitions

Result

A specialized Result type for metric operations.
