// A TracerProvider is the collection destination of all Spans from Tracers it
|
|
// provides, it represents a unique telemetry collection pipeline. How that
|
|
// pipeline is defined, meaning how those Spans are collected, processed, and
|
|
// where they are exported, depends on its implementation. Instrumentation
|
|
// authors do not need to define this implementation, rather just use the
|
|
// provided Tracers to instrument code.
|
|
//
|
|
// Commonly, instrumentation code will accept a TracerProvider implementation
|
|
// at runtime from its users or it can simply use the globally registered one
|
|

// Tracer returns a unique Tracer scoped to be used by instrumentation code
|
|
// to trace computational workflows. The scope and identity of that
|
|
// instrumentation code is uniquely defined by the name and options passed.
|
|
//
|
|
// The passed name needs to uniquely identify instrumentation code.
|
|
// Therefore, it is recommended that name is the Go package name of the
|
|
// library providing instrumentation (note: not the code being
|
|
// instrumented). Instrumentation libraries can have multiple versions,
|
|
// therefore, the WithInstrumentationVersion option should be used to
|
|
// distinguish these different codebases. Additionally, instrumentation
|
|
// libraries may sometimes use traces to communicate different domains of
|
|
// workflow data (i.e. using spans to communicate workflow events only). If
|
|
// this is the case, the WithScopeAttributes option should be used to
|
|
// uniquely identify Tracers that handle the different domains of workflow
|
|
// data.
|
|
//
|
|
// If the same name and options are passed multiple times, the same Tracer
|
|
// will be returned (it is up to the implementation if this will be the
|
|
// same underlying instance of that Tracer or not). It is not necessary to
|
|
// call this multiple times with the same name and options to get an
|
|
// up-to-date Tracer. All implementations will ensure any TracerProvider
|
|
// configuration changes are propagated to all provided Tracers.
|
|
//
|
|
// If name is empty, then an implementation defined default name will be
|
|
// used instead.
|
|
//
|
|
// This method is safe to call concurrently.
