// Package metric provides an implementation of the OpenTelemetry metrics SDK.
|
||
|
|
//
|
||
|
|
// See https://opentelemetry.io/docs/concepts/signals/metrics/ for information
|
||
|
|
// about the concept of OpenTelemetry metrics and
|
||
|
|
// https://opentelemetry.io/docs/concepts/components/ for more information
|
||
|
|
// about OpenTelemetry SDKs.
|
||
|
|
//
|
||
|
|
// The entry point for the metric package is the MeterProvider. It is the
|
||
|
|
// object that all API calls use to create Meters, instruments, and ultimately
|
||
|
|
// make metric measurements. Also, it is an object that should be used to
|
||
|
|
// control the life-cycle (start, flush, and shutdown) of the SDK.
|
||
|
|
//
|
||
|
|
// A MeterProvider needs to be configured to export the measured data, this is
|
||
|
|
// done by configuring it with a Reader implementation (using the WithReader
|
||
|
|
// MeterProviderOption). Readers take two forms: ones that push to an endpoint
|
||
|
|
// (NewPeriodicReader), and ones that an endpoint pulls from. See
|
||
|
|
// [go.opentelemetry.io/otel/exporters] for exporters that can be used as
|
||
|
|
// or with these Readers.
|
||
|
|
//
|
||
|
|
// Each Reader, when registered with the MeterProvider, can be augmented with a
|
||
|
|
// View. Views allow users that run OpenTelemetry instrumented code to modify
|
||
|
|
// the generated data of that instrumentation.
|
||
|
|
//
|
||
|
|
// The data generated by a MeterProvider needs to include information about its
|
||
|
|
// origin. A MeterProvider needs to be configured with a Resource, using the
|
||
|
|
// WithResource MeterProviderOption, to include this information. This Resource
|
||
|
|
// should be used to describe the unique runtime environment instrumented code
|
||
|
|
// is being run on. That way when multiple instances of the code are collected
|
||
|
|
// at a single endpoint their origin is decipherable.
|
||
|
|
//
|
||
|
|
// See [go.opentelemetry.io/otel/metric] for more information about
|
||
|
|
// the metric API.
