// OpenTelemetry views allow you to override the default behaviour
|
|
// of the SDK. It defines how data should be collected for certain
|
|
// instruments.
|
|
//
|
|
// OpenCensus allowed views to be registered globally to simplify
|
|
// setup. In contrast, OpenTelemetry requires views to be provided
|
|
// when creating a [MeterProvider] using the [WithView] option. This
|
|
// was done to provide flexibility of having multiple metrics pipelines.
|
|
//
|
|
// To provide a similar UX experience the globalviews provides a similar
|
|
// way to register OTel views globally. This allows Knative maintainers
|
|
// to author packages with metrics and include views that can be consumed
|
|
// by packages such as sharedmain.
