Types

type Service

type Service struct {
	ServiceName   string `json:"serviceName"`
	OperationName string `json:"operationName"`
}

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

ServiceOperationStorage stores service to operation pairs.

func NewServiceOperationStorage added in v0.5.2

func NewServiceOperationStorage(
	ctx context.Context,
	client es.Client,
	metricsFactory metrics.Factory,
	logger *zap.Logger,
	cacheTTL time.Duration,
) *ServiceOperationStorage

NewServiceOperationStorage returns a new ServiceOperationStorage.

func (*ServiceOperationStorage) Write added in v0.5.2

func (s *ServiceOperationStorage) Write(indexName string, jsonSpan *jModel.Span) error

Write saves a service to operation pair.

type SpanReader

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

SpanReader can query for and load traces from ElasticSearch

func (*SpanReader) FindTraces

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

FindTraces retrieves traces that match the traceQuery

func (*SpanReader) GetOperations

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

type SpanWriter

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

SpanWriter is a wrapper around elastic.Client

func NewSpanWriter

func NewSpanWriter(
	client es.Client,
	logger *zap.Logger,
