Functions

func NewTChanZipkinCollectorInheritedClient 

func NewTChanZipkinCollectorInheritedClient(thriftService string, client thrift.TChanClient) *tchanZipkinCollectorClient

func NewTChanZipkinCollectorServer 

func NewTChanZipkinCollectorServer(handler TChanZipkinCollector) thrift.TChanServer

NewTChanZipkinCollectorServer wraps a handler for TChanZipkinCollector so it can be registered with a thrift.Server.

Types

type Annotation 

type Annotation struct {
	Timestamp int64     `thrift:"timestamp,1" json:"timestamp"`
	Value     string    `thrift:"value,2" json:"value"`
	Host      *Endpoint `thrift:"host,3" json:"host,omitempty"`
}

An annotation is similar to a log statement. It includes a host field which allows these events to be attributed properly, and also aggregatable.

Attributes:

  • Timestamp: Microseconds from epoch.

This value should use the most precise value possible. For example, gettimeofday or syncing nanoTime against a tick of currentTimeMillis.

  • Value
  • Host: Always the host that recorded the event. By specifying the host you allow

rollup of all events (such as client requests to a service) by IP address.

func (*Annotation) GetTimestamp

type AnnotationType 

type AnnotationType int64
const (
	AnnotationType_BOOL   AnnotationType = 0
	AnnotationType_BYTES  AnnotationType = 1
	AnnotationType_I16    AnnotationType = 2
	AnnotationType_I32    AnnotationType = 3
	AnnotationType_I64    AnnotationType = 4
	AnnotationType_DOUBLE AnnotationType = 5
	AnnotationType_STRING AnnotationType = 6
)

func AnnotationTypeFromString 

func AnnotationTypeFromString(s string) (AnnotationType, error)

func AnnotationTypePtr 

func AnnotationTypePtr(v AnnotationType) *AnnotationType

func (AnnotationType) MarshalText 

func (p AnnotationType) MarshalText() ([]byte, error)

func (AnnotationType) String 

func (p AnnotationType) String() string

func (*AnnotationType) UnmarshalText 

func (p *AnnotationType) UnmarshalText(text []byte) error

type BinaryAnnotation 

type BinaryAnnotation struct {
	Key            string         `thrift:"key,1" json:"key"`
	Value          []byte         `thrift:"value,2" json:"value"`
	AnnotationType AnnotationType `thrift:"annotation_type,3" json:"annotation_type"`
	Host           *Endpoint      `thrift:"host,4" json:"host,omitempty"`
}

Binary annotations are tags applied to a Span to give it context. For example, a binary annotation of "http.uri" could the path to a resource in a RPC call.

Binary annotations of type STRING are always queryable, though more a historical implementation detail than a structural concern.

Binary annotations can repeat, and vary on the host. Similar to Annotation, the host indicates who logged the event. This allows you to tell the difference between the client and server side of the same key. For example, the key "http.uri" might be different on the client and server side due to rewriting, like "/api/v1/myresource" vs "/myresource. Via the host field, you can see the different points of view, which often help in debugging.

Attributes:

  • Key
  • Value
  • AnnotationType
  • Host: The host that recorded tag, which allows you to differentiate between

multiple tags with the same key. There are two exceptions to this.

When the key is CLIENT_ADDR or SERVER_ADDR, host indicates the source or destination of an RPC. This exception allows zipkin to display network context of uninstrumented services, or clients such as web browsers.

type Endpoint 

type Endpoint struct {
	Ipv4        int32  `thrift:"ipv4,1" json:"ipv4"`
	Port        int16  `thrift:"port,2" json:"port"`
	ServiceName string `thrift:"service_name,3" json:"service_name"`
	Ipv6        []byte `thrift:"ipv6,4" json:"ipv6,omitempty"`
}

Indicates the network context of a service recording an annotation with two exceptions.

When a BinaryAnnotation, and key is CLIENT_ADDR or SERVER_ADDR, the endpoint indicates the source or destination of an RPC. This exception allows zipkin to display network context of uninstrumented services, or clients such as web browsers.

Attributes:

  • Ipv4: IPv4 host address packed into 4 bytes.

Ex for the ip 1.2.3.4, it would be (1 << 24) | (2 << 16) | (3 << 8) | 4

  • Port: IPv4 port

Note: this is to be treated as an unsigned integer, so watch for negatives.

Conventionally, when the port isn't known, port = 0.

  • ServiceName: Service name in lowercase, such as "memcache" or "zipkin-web"

Conventionally, when the service name isn't known, service_name = "unknown".

  • Ipv6: IPv6 host address packed into 16 bytes. Ex Inet6Address.getBytes()

	// unused field # 2
	Name        string        `thrift:"name,3" json:"name"`
	ID          int64         `thrift:"id,4" json:"id"`
	ParentID    *int64        `thrift:"parent_id,5" json:"parent_id,omitempty"`
	Annotations []*Annotation `thrift:"annotations,6" json:"annotations"`
	// unused field # 7
	BinaryAnnotations []*BinaryAnnotation `thrift:"binary_annotations,8" json:"binary_annotations"`
	Debug             bool                `thrift:"debug,9" json:"debug,omitempty"`
	Timestamp         *int64              `thrift:"timestamp,10" json:"timestamp,omitempty"`
	Duration          *int64              `thrift:"duration,11" json:"duration,omitempty"`
	TraceIDHigh       *int64              `thrift:"trace_id_high,12" json:"trace_id_high,omitempty"`
}

A trace is a series of spans (often RPC calls) which form a latency tree.

The root span is where trace_id = id and parent_id = Nil. The root span is usually the longest interval in the trace, starting with a SERVER_RECV annotation and ending with a SERVER_SEND.

Attributes:

  • TraceID
  • Name: Span name in lowercase, rpc method for example

Conventionally, when the span name isn't known, name = "unknown".

  • ID
  • ParentID
  • Annotations
  • BinaryAnnotations
  • Debug
  • Timestamp: Microseconds from epoch of the creation of this span.

This value should be set directly by instrumentation, using the most precise value possible. For example, gettimeofday or syncing nanoTime against a tick of currentTimeMillis.

For compatibilty with instrumentation that precede this field, collectors or span stores can derive this via Annotation.timestamp. For example, SERVER_RECV.timestamp or CLIENT_SEND.timestamp.

This field is optional for compatibility with old data: first-party span stores are expected to support this at time of introduction.

  • Duration: Measurement of duration in microseconds, used to support queries.

This value should be set directly, where possible. Doing so encourages precise measurement decoupled from problems of clocks, such as skew or NTP updates causing time to move backwards.

For compatibilty with instrumentation that precede this field, collectors or span stores can derive this by subtracting Annotation.timestamp. For example, SERVER_SEND.timestamp - SERVER_RECV.timestamp.

If this field is persisted as unset, zipkin will continue to work, except duration query support will be implementation-specific. Similarly, setting this field non-atomically is implementation-specific.

This field is i64 vs i32 to support spans longer than 35 minutes.

  • TraceIDHigh: Optional unique 8-byte additional identifier for a trace. If non zero, this

means the trace uses 128 bit traceIds instead of 64 bit.
