Constants ¶
const (
// ChildOf means a span is the child of another span
ChildOf ReferenceType = "CHILD_OF"
// FollowsFrom means a span follows from another span

Types ¶
type DependencyLink ¶
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 ¶ added in v1.16.0
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.
