Functions

func Extract

func Extract(ctx context.Context, p propagation.TextMapPropagator, metadata *metadata.MD) (
	baggage.Baggage, sdktrace.SpanContext)

Extract extracts the metadata from ctx.

func InitAgent

func InitAgent(o Options)

func Inject

func Inject(ctx context.Context, p propagation.TextMapPropagator, metadata *metadata.MD)

Inject injects the metadata into ctx.

func ParseFullMethod

func ParseFullMethod(fullMethod string) (string, []attribute.KeyValue)

ParseFullMethod returns the method name and attributes.

func PeerAttr

func PeerAttr(addr string) []attribute.KeyValue

PeerAttr returns the peer attributes.

func PeerFromCtx

func PeerFromCtx(ctx context.Context) string

PeerFromCtx returns the peer from ctx.

func SpanInfo

func SpanInfo(fullMethod, peerAddress string) (string, []attribute.KeyValue)

SpanInfo returns the span info.

func StatusCodeAttr

func StatusCodeAttr(c gcodes.Code) attribute.KeyValue

StatusCodeAttr returns an attribute.KeyValue that represents the give c.

Types

type Options

type Options struct {
	Name     string  `json:"name"`     // jeager 名称
	Endpoint string  `json:"endpoint"` // jeager 地址
	Sampler  float64 `json:"sampler"`  // 采样率
	Batcher  string  `json:"batcher"`  // 批量发送
}

Options 这个配置和 业务中 app 中的 tracing 冗余，为的是将 tracing 从业务中解耦出来
