A span event Span events are emitted whenever a span lifecycle event happens and are thus rather low-level by nature.

Used in: Update

• oneof event

  • SpanEvent.Span new_span = 1

  • SpanEvent.Enter enter_span = 2

  • SpanEvent.Exit exit_span = 3

  • SpanEvent.Close close_span = 4

  • SpanEvent.Recorded recorded = 5

Used in: SpanEvent

• uint64 span_id = 1

• uint64 thread_id = 2

• optional google.protobuf.Timestamp at = 3

Span recorded values for a list of fields.

Used in: SpanEvent

• uint64 span_id = 1

  An Id that uniquely identifies it in relation to other spans.

• repeated common.Field fields = 2

  Data recorded by the span.

Represents a period of time in which a program was executing in a particular context. Corresponds to `Span` in the `tracing` crate.

Used in: SpanEvent

• uint64 id = 1

  An Id that uniquely identifies it in relation to other spans.

• uint64 metadata_id = 2

  Identifier for metadata describing static characteristics of all spans originating from that call site, such as its name, source code location, verbosity level, and the names of its fields.

• repeated common.Field fields = 3

  User-defined key-value pairs of arbitrary data that describe the context the span represents.

• optional uint64 parent = 4

• optional google.protobuf.Timestamp at = 5

  Timestamp for the span.

Used in: instrument.Update

• repeated SpanEvent span_events = 1

  A list of span events that happened since the last update.

• uint64 dropped_events = 2

  A count of how many log events were dropped because the event buffer was at capacity. If everything is working correctly, this should be 0. If this number is greater than zero this indicates the event buffers capacity should be increased or the publish interval decreased.
