Module metrics
Expand description
The crust of the OpenTelemetry metrics SDK.
§Configuration
The metrics SDK configuration is stored with each SdkMeterProvider. Configuration for Resources, views, and [ManualReader] or PeriodicReader instances can be specified.
§Example
use opentelemetry::global;
use opentelemetry::KeyValue;
use opentelemetry_sdk::{metrics::SdkMeterProvider, Resource};
// Generate SDK configuration, resource, views, etc
let resource = Resource::builder().build(); // default attributes about the current process
// Create a meter provider with the desired config
let meter_provider = SdkMeterProvider::builder().with_resource(resource).build();
global::set_meter_provider(meter_provider.clone());
// Use the meter provider to create meter instances
let meter = global::meter("my_app");
// Create instruments scoped to the meter
let counter = meter
.u64_counter("power_consumption")
.with_unit("kWh")
.build();
// use instruments to record measurements
counter.add(10, &[KeyValue::new("rate", "standard")]);
// shutdown the provider at the end of the application to ensure any metrics not yet
// exported are flushed.
meter_provider.shutdown().unwrap();
Modules§
- data
- Types for delivery of pre-aggregated metric time series data.
- exporter
- Interfaces for exporting metrics
Structs§
- Instrument
- Describes the properties of an instrument at creation, used for filtering in
views. This is utilized in the
with_view
methods onMeterProviderBuilder
to customize metric output. - Meter
Provider Builder - Configuration options for a MeterProvider.
- Periodic
Reader - A
MetricReader
that periodically collects and exports metrics at a configurable interval. - Periodic
Reader Builder - Configuration options for PeriodicReader.
- SdkMeter
Provider - Handles the creation and coordination of Meters.
- Stream
- Describes the stream of data an instrument produces. Used in
with_view
methods onMeterProviderBuilder
to customize the metric output. - Stream
Builder - A builder for creating Stream objects.
Enums§
- Instrument
Kind - The identifier of a group of instruments that all perform the same function.
- Temporality
- Defines the window that an aggregation was calculated over.
