- title: Endpoint
- description: The network context of a node in the service graph
- required:
- - serviceName
- properties:
- serviceName:
- type: string
- description: |
- Lower-case label of this node in the service graph, such as "favstar". Set
- to empty string if unknown.
-
- This is a primary label for trace lookup and aggregation, so it should be
- intuitive and consistent. Many use a name from service discovery.
- ipv4:
- type: string
- format: ipv4
- description: |
- The text representation of the primary IPv4 address associated with this
- connection. Ex. 192.168.99.100 Absent if unknown.
- ipv6:
- type: string
- format: ipv6
- description: |
- The text representation of the primary IPv6 address associated with a
- connection. Ex. 2001:db8::c001 Absent if unknown.
-
- Prefer using the ipv4 field for mapped addresses.
- port:
- type: integer
- description: |
- Depending on context, this could be a listen port or the client-side of a
- socket. Absent if unknown. Please don't set to zero.
- Annotation:
- title: Annotation
- type: object
- required:
- - timestamp
- - value
- description: |
- Associates an event that explains latency with a timestamp.
- Unlike log statements, annotations are often codes. Ex. "sr" for ServerReceive
- properties:
- timestamp:
- type: integer
- description: |
- Epoch **microseconds** of this event.
-
- For example, 1502787600000000 corresponds to 2017-08-15 09:00 UTC
-
- This value should be set directly by instrumentation, using the most precise
- value possible. For example, gettimeofday or multiplying epoch millis by 1000.
- value:
- type: string
- description: |
- Usually a short tag indicating an event, like "sr"
-
- While possible to add larger data, such as garbage collection details, low
- cardinality event names both keep the size of spans down and also are easy
- to search against.
- endpoint:
- $ref: "#/definitions/Endpoint"
- description: |
- The host that recorded this span, primarily for query by service name.
-
- Instrumentation should always record this. Usually, absent implies late
- data. The IP address corresponding to this is usually the site local or
- advertised service address. When present, the port indicates the listen
- port.
- BinaryAnnotation:
- title: BinaryAnnotation
- type: object
- required:
- - key
- - value
- description: |
- Adds context to a span, for search, viewing and analysis.
-
- For example, a key "your_app.version" would let you lookup traces by version.
- A tag "sql.query" isn't searchable, but it can help in debugging when viewing
- a trace.
- properties:
- key:
- type: string
- value:
- type: string
- endpoint:
- $ref: "#/definitions/Endpoint"
- description: |
- The host that recorded this span, primarily for query by service name.
-
- There is an exception, when the key is "sa", "ca" or "ma" this is an
- address annotation. In such case, the endpoint is not what recorded the
- span, rather the remote address. The value field is set to boolean true
- in this case. This feature was refactored in v2 format as "remoteEndpoint"

- Randomly generated, unique identifier for a trace, set on all spans within it.
-
- Encoded as 16 or 32 lowercase hex characters in big endian byte order,
- corresponding to 64 or 128 bits,
- For example, a 128bit trace ID looks like 4e441824ec2b6a44ffdc9bb9a6453df3
- name:
- type: string
- description: |
- The logical operation this span represents in lowercase (e.g. rpc method).
- Set to empty string if unknown.
-
- As these are lookup labels, take care to ensure names are low cardinality.
- For example, do not embed variables into the name.

- description: |
- Unique 64bit identifier for this operation within the trace.
-
- Encoded as 16 lowercase hex characters. For example ffdc9bb9a6453df3
- timestamp:
- type: integer
- format: int64
- description: |
- Epoch microseconds of the start of this span, possibly absent if
- incomplete.
-
- For example, 1502787600000000 corresponds to 2017-08-15 09:00 UTC
-
- This value should be set directly by instrumentation, using the most
- precise value possible. For example, gettimeofday or multiplying epoch
- millis by 1000.
-
- There are three known edge-cases where this could be reported absent.
- * A span was allocated but never started (ex not yet received a timestamp)
- * The span's start event was lost
- * Data about a completed span (ex tags) were sent after the fact
- duration:
- type: integer
- format: int64
- minimum: 1
- description: |
- Duration in **microseconds** of the critical path, if known. Durations of less
- than one are rounded up. Duration of children can be longer than their
- parents due to asynchronous operations.
-
- For example 150 milliseconds is 150000 microseconds.
- debug:
- type: boolean
- description: |
- True is a request to store this span even if it overrides sampling policy.
-
- This is true when the `X-B3-Flags` header has a value of 1.

- (often RPC calls) which nest to form a latency tree. Spans are in the same
- trace when they share the same trace ID. The parent_id field establishes the
- position of one span in the tree.
-
- The root span is where parent_id is Absent and usually has the longest
- duration in the trace. However, nested asynchronous work can materialize as
- child spans whose duration exceed the root span.
-
- Spans usually represent remote activity such as RPC calls, or messaging
- producers and consumers. However, they can also represent in-process
- activity in any position of the trace. For example, a root span could
- represent a server receiving an initial client request. A root span could
- also represent a scheduled job that has no remote context.

- description: |
- Randomly generated, unique identifier for a trace, set on all spans within it.
-
- Encoded as 16 or 32 lowercase hex characters corresponding to 64 or 128 bits.
- For example, a 128bit trace ID looks like 4e441824ec2b6a44ffdc9bb9a6453df3
- name:
- type: string
- description: |
- The logical operation this span represents in lowercase (e.g. rpc method).
- Leave absent if unknown.
-
- As these are lookup labels, take care to ensure names are low cardinality.
- For example, do not embed variables into the name.

- description: |
- Unique 64bit identifier for this operation within the trace.

- kind:
- type: string
- enum:
- - CLIENT
- - SERVER
- - PRODUCER
- - CONSUMER
- description: |
- When present, kind clarifies timestamp, duration and remoteEndpoint. When
- absent, the span is local or incomplete. Unlike client and server, there
- is no direct critical path latency relationship between producer and
- consumer spans.
-
- * `CLIENT`
- * timestamp is the moment a request was sent to the server. (in v1 "cs")
- * duration is the delay until a response or an error was received. (in v1 "cr"-"cs")
- * remoteEndpoint is the server. (in v1 "sa")
- * `SERVER`
- * timestamp is the moment a client request was received. (in v1 "sr")
- * duration is the delay until a response was sent or an error. (in v1 "ss"-"sr")
- * remoteEndpoint is the client. (in v1 "ca")
- * `PRODUCER`
- * timestamp is the moment a message was sent to a destination. (in v1 "ms")
- * duration is the delay sending the message, such as batching.
- * remoteEndpoint is the broker.
- * `CONSUMER`
- * timestamp is the moment a message was received from an origin. (in v1 "mr")
- * duration is the delay consuming the message, such as from backlog.
- * remoteEndpoint - Represents the broker. Leave serviceName absent if unknown.
- timestamp:
- type: integer
- format: int64
- description: |
- Epoch microseconds of the start of this span, possibly absent if
- incomplete.
-
- For example, 1502787600000000 corresponds to 2017-08-15 09:00 UTC
-
- This value should be set directly by instrumentation, using the most
- precise value possible. For example, gettimeofday or multiplying epoch
- millis by 1000.
-
- There are three known edge-cases where this could be reported absent.
- * A span was allocated but never started (ex not yet received a timestamp)
- * The span's start event was lost
- * Data about a completed span (ex tags) were sent after the fact
- duration:
- type: integer
- format: int64
- minimum: 1
- description: |
- Duration in **microseconds** of the critical path, if known. Durations of less
- than one are rounded up. Duration of children can be longer than their
- parents due to asynchronous operations.
-
- For example 150 milliseconds is 150000 microseconds.
- debug:
- type: boolean
- description: |
- True is a request to store this span even if it overrides sampling policy.
-
- This is true when the `X-B3-Flags` header has a value of 1.
- shared:
- type: boolean
- description: 'True if we are contributing to a span started by another tracer (ex on a different host).'
- localEndpoint:
- $ref: "#/definitions/Endpoint"
- description: |
- The host that recorded this span, primarily for query by service name.
-
- Instrumentation should always record this. Usually, absent implies late
- data. The IP address corresponding to this is usually the site local or
- advertised service address. When present, the port indicates the listen
- port.
- remoteEndpoint:
- $ref: "#/definitions/Endpoint"
- description: |
- When an RPC (or messaging) span, indicates the other side of the
- connection.
-
- By recording the remote endpoint, your trace will contain network context
- even if the peer is not tracing. For example, you can record the IP from
- the `X-Forwarded-For` header or the service name and socket of a remote
- peer.

- The count of traced calls between services, or between a service and a broker.
-
- The direction of the link is parent to child, and can be one of:
- * client to server
- * producer to broker
- * broker to consumer
-
- Note: This is related to span ID count between a sender and receiver, but there
- is nuance that makes it more difficult than counting unique span IDs. Ex. the
- parent or child might be uninstrumented: detected via the remote endpoint. There
- can also be scenarios where both sides are instrumented. Please use existing tools
- such as zipkin-dependencies to derive links as they avoid under or over counting.
