Types

type SpanReader

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

SpanReader can query for and load traces from AliCloud Log Service

func (*SpanReader) FindTraces

func (s *SpanReader) FindTraces(traceQuery *spanstore.TraceQueryParameters) ([]*model.Trace, error)

FindTraces retrieves traces that match the traceQuery

func (*SpanReader) GetOperations

func (s *SpanReader) GetOperations(service string) ([]string, error)

GetOperations returns all operations for a specific service traced by Jaeger

func (*SpanReader) GetServices

func (s *SpanReader) GetServices() ([]string, error)

GetServices returns all services traced by Jaeger, ordered by frequency

func (*SpanReader) GetTrace

func (s *SpanReader) GetTrace(traceID model.TraceID) (*model.Trace, error)

GetTrace takes a traceID and returns a Trace associated with that traceID
