otel/trace 包常量、类型、方法 快捷链接 otel/trace 常量

Variables

var ContextWithRemoteSpanContext = trace.ContextWithRemoteSpanContext

otel/trace funcs

var ContextWithSpan = trace.ContextWithSpan

var ContextWithSpanContext = trace.ContextWithSpanContext

var GetErrorHandler = otel.GetErrorHandler

var GetTextMapPropagator = otel.GetTextMapPropagator

var GetTracer = otel.Tracer

注意此函数改名

var GetTracerProvider = otel.GetTracerProvider

otel funcs

var Handle = otel.Handle

var LinkFromContext = trace.LinkFromContext

var OtelVersion = otel.Version

var SetErrorHandler = otel.SetErrorHandler

var SetLogger = otel.SetLogger

var SetTextMapPropagator = otel.SetTextMapPropagator

var SetTracerProvider = otel.SetTracerProvider

func WithTextMapPropagator

func WithTextMapPropagator(propagator propagation.TextMapPropagator)

Types

type Config

type Config struct {
	// 采样率
	SampleRate float64
	// 采样器
	ExporterName EXPORTER_NAME
	// OLTP采样器服务地址
	ExporterEndpoint string
	// OLTP采样器服务名称
	ServiceName string
}

func DefaultConfig

func DefaultConfig() *Config

type EXPORTER_NAME

type EXPORTER_NAME string

const (
	EXPORTER_NAME_JAEGER EXPORTER_NAME = "jaeger"
	EXPORTER_NAME_OLTP   EXPORTER_NAME = "oltp"
	EXPORTER_NAME_STDOUT EXPORTER_NAME = "stdout"
)

type ErrorHandler

type ErrorHandler = otel.ErrorHandler

otel types

type ErrorHandlerFunc

type ErrorHandlerFunc = otel.ErrorHandlerFunc

type Provider

type Provider interface {
	trace.TracerProvider
}

重要，此接口必须实现 依托实现的接口是TracerProvider 第三方实现的Tracer必须实现Provider接口

func New

func New(config *Config) Provider

func NewProvider

func NewProvider(config *Config, exp sdktrace.SpanExporter) Provider

type Span

type Span = trace.Span

otel/trace interface

type SpanContext

type SpanContext = trace.SpanContext

type Tracer

type Tracer = trace.Tracer

此处Tracer使用otel的API作为标准来实现
