type ComponentLibrary ¶ added in v0.1.1

type ComponentLibrary int32

ComponentLibrary represents a specific library or component where the current span is running. This type helps identify the origin of the span within SkyWalking's tracing UI, making it easier to debug and understand distributed traces.

Each library or component is associated with a unique identifier that is displayed in the SkyWalking UI. These identifiers allow developers to distinguish between various technologies in use within their traced application.

A complete list of available component libraries and their IDs can be found in the SkyWalking repository: https://github.com/apache/skywalking/blob/master/oap-server/server-starter/src/main/resources/component-libraries.yml

const (
	Unknown      ComponentLibrary = 0
	GoRedis      ComponentLibrary = 7
	PostgreSQL   ComponentLibrary = 22
	GoKafka      ComponentLibrary = 27
	RabbitMQ     ComponentLibrary = 51
	GoHttpServer ComponentLibrary = 5004
	GoMysql      ComponentLibrary = 5012
)

func (c ComponentLibrary) AsInt32() int32

type Span ¶

type Span struct {
	// contains filtered or unexported fields
}

Span represents a unit of work in a distributed trace.

A span captures timing, metadata, and contextual information about a specific operation within a trace. This struct provides abstraction over the underlying SkyWalking `go2sky.Span`, enabling more intuitive interaction and additional functionality.

func (s *Span) AddEvent(descriptions ...string)

func (s *Span) Context() tengcoruxTracer.SpanContext

func (s *Span) End()

func (s *Span) RecordError(err error)

func (s *Span) SetAttributes(attributes ...attribute.KeyValue)

type SpanContext ¶

type SpanContext struct {
	// contains filtered or unexported fields
}

SpanContext is a wrapper around a Go context for which it stores the underlying context of a span. It provides convenient methods for interacting with tracing information. The SpanContext is designed to be used wherever tracing context needs to be passed or extracted within an application.

func (sc *SpanContext) Context() context.Context

func (sc *SpanContext) SpanID() string

func (sc *SpanContext) TraceID() string

type Tracer ¶

type Tracer struct {
	// contains filtered or unexported fields
}

func NewTracer(exportAddr, serviceName string, opts ...go2sky.TracerOption) (*Tracer, error)

func (t *Tracer) Shutdown(_ context.Context) error

func (t *Tracer) SpanFromContext(ctx context.Context) tengcoruxTracer.Span

func (t *Tracer) StartSpan(ctx context.Context, name string, opts ...tengcoruxTracer.StartSpanOption) (context.Context, tengcoruxTracer.Span)
