Types

type DependencyLink struct {
	Parent    string `json:"parent"`
	Child     string `json:"child"`
	CallCount uint64 `json:"callCount"`
}

DependencyLink shows dependencies between services

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 Operation

type Operation struct {
	Name     string `json:"name"`
	SpanKind string `json:"spanKind"`
}

Operation defines the data in the operation response when query operation by service and span kind

type Process

type Process struct {
	ServiceName string     `json:"serviceName"`
	Tags        []KeyValue `json:"tags"`
}

Process is the process emitting a set of spans

type ProcessID

type ProcessID string

ProcessID is a hashed value of the Process struct that is unique within the trace.

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 Span

type Span struct {
	TraceID       TraceID     `json:"traceID"`
	SpanID        SpanID      `json:"spanID"`
	ParentSpanID  SpanID      `json:"parentSpanID,omitempty"` // deprecated
	Flags         uint32      `json:"flags,omitempty"`
	OperationName string      `json:"operationName"`
	References    []Reference `json:"references"`
	StartTime     uint64      `json:"startTime"` // microseconds since Unix epoch
	Duration      uint64      `json:"duration"`  // microseconds
	Tags          []KeyValue  `json:"tags"`
	Logs          []Log       `json:"logs"`
	ProcessID     ProcessID   `json:"processID,omitempty"`
	Process       *Process    `json:"process,omitempty"`
	Warnings      []string    `json:"warnings"`
}

Span is a span denoting a piece of work in some infrastructure When converting to UI model, ParentSpanID and Process should be dereferenced into References and ProcessID, respectively. When converting to ES model, ProcessID and Warnings should be omitted. Even if included, ES with dynamic settings off will automatically ignore unneeded fields.

type SpanID

type SpanID string

SpanID is the id of a span

type Trace

type Trace struct {
	TraceID   TraceID               `json:"traceID"`
	Spans     []Span                `json:"spans"`
	Processes map[ProcessID]Process `json:"processes"`
	Warnings  []string              `json:"warnings"`
}

Trace is a list of spans

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.
