spankind

SpanKind is the type of span. Can be used to specify additional relationships between spans in addition to a parent/child relationship.

Constants​

internal​

type: U64

Indicates that the span represents an internal operation within an application, as opposed to an operation happening at the boundaries. Default value.

producer​

type: U64

Indicates that the span describes a producer sending a message to a broker.

Unlike CLIENT and SERVER, there is often no direct critical path latency relationship between producer and consumer spans. A PRODUCER span ends when the message was accepted by the broker while the logical processing of the message might span a much longer time.

unspecified​

type: U64

Unspecified. Do NOT use as default. Implementations MAY assume SpanKind to be INTERNAL when receiving UNSPECIFIED.

server​

type: U64

Indicates that the span covers server-side handling of an RPC or other remote network request.

consumer​

type: U64

Indicates that the span describes consumer receiving a message from a broker. Like the PRODUCER kind, there is often no direct critical path latency relationship between producer and consumer spans.

client​

type: U64

Indicates that the span describes a request to some remote service.

Functions​

make_default()​

The default function returns the preferred default spankind if/when none is specified
