Types ¶
type Annotation ¶
type Annotation struct {
Timestamp *int64 `json:"timestamp,omitempty"`
Value *string `json:"value,omitempty"`
}
Annotation associates an event that explains latency with a timestamp. Unlike log statements, annotations are often codes. Ex. “ws” for WireSend
type Endpoint ¶
type Endpoint struct {
ServiceName *string `json:"serviceName,omitempty"`
Ipv4 *string `json:"ipv4,omitempty"`
Ipv6 *string `json:"ipv6,omitempty"`
Port *int32 `json:"port,omitempty"`
}
Endpoint is the network context of a node in the service graph
type MiddlewareConstructor ¶
A MiddlewareConstructor is used by FromChain to chain together a bunch of sinks that forward to each other
func NextWrap ¶
func NextWrap(wrapping NextSink) MiddlewareConstructor
NextWrap wraps a NextSink to make it usable by MiddlewareConstructor
type Sink ¶
A Sink is an object that can accept traces and do something with them, like forward them to some endpoint
func FromChain ¶
func FromChain(endSink Sink, sinks ...MiddlewareConstructor) Sink
FromChain creates an endpoint Sink that sends calls between multiple middlewares for things like counting traces in between.
type Span ¶
type Span struct {
TraceID string `json:"traceId"` // required
Name *string `json:"name,omitempty"`
ParentID *string `json:"parentId,omitempty"`
ID string `json:"id"` // required
Kind *string `json:"kind,omitempty"`
Timestamp *int64 `json:"timestamp,omitempty"`
Duration *int64 `json:"duration,omitempty"`
Debug *bool `json:"debug,omitempty"`
LocalEndpoint *Endpoint `json:"localEndpoint,omitempty"`
RemoteEndpoint *Endpoint `json:"remoteEndpoint,omitempty"`
Annotations []*Annotation `json:"annotations,omitempty"`
Tags map[string]string `json:"tags,omitempty"`
Meta map[interface{}]interface{} `json:"-"` // non serializeable field to hold any meta data we want to keep around
}
Span defines a span
