Types

type KeyValue

type KeyValue struct {
	Key   string      `json:"key"`
	Type  ValueType   `json:"type,omitempty"`
	Value interface{} `json:"value"`
}

KeyValue is a key-value pair with typed value.

type Log

type Log struct {
	Timestamp uint64     `json:"timestamp"`
	Fields    []KeyValue `json:"fields"`
}

Log is a log emitted in a span

type Process

type Process struct {
	ServiceName string     `json:"serviceName"`
	Tags        []KeyValue `json:"tags"`
	// Alternative representation of tags for better kibana support
	Tag map[string]interface{} `json:"tag,omitempty"`
}

Process is the process emitting a set of spans

type Reference

type Reference struct {
	RefType ReferenceType `json:"refType"`
	TraceID TraceID       `json:"traceID"`
	SpanID  SpanID        `json:"spanID"`
}

Reference is a reference from one span to another

type ReferenceType

type ReferenceType string

ReferenceType is the reference type of one span to another

type Service

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

Service is the JSON struct for service:operation documents in ElasticSearch

type SpanID

type SpanID string

SpanID is the id of a span

type TraceID

type TraceID string

TraceID is the shared trace ID of all spans in the trace.

type ValueType

type ValueType string

ValueType is the type of a value stored in KeyValue struct.
