Type Members

  1. abstract class Delayed extends Span

    A Span representing an operation that will not start processing immediately after the Span is created but rather when the start method is called.

    A Span representing an operation that will not start processing immediately after the Span is created but rather when the start method is called. Additionally to a regular Span, a Delayed Span will automatically track the wait time metric and add a "span.started" mark on the Span when the Start method is called. The three relevant instants when working with Delayed Spans are:

    Created |=====================| <- Wait Time |====================================================| <- Elapsed Time |==============================| <- Processing Time Started Finished

    Unless metrics tracking is disabled, a Delayed Span will track the "span.wait-time" metric with the time between creating and starting the Span, and the "span.elapsed-time" tracking the time between creating and finishing the Span. The "span.processing-time" remains the same, tracking the time between starting and finishing the Span.

  2. case class Finished(id: Identifier, trace: Trace, parentId: Identifier, operationName: String, hasError: Boolean, wasDelayed: Boolean, from: Instant, to: Instant, kind: Kind, position: Position, tags: TagSet, metricTags: TagSet, marks: Seq[Mark], links: Seq[Link]) extends Product with Serializable

    Represents a Span that has already been finished and should be exposed to the SpanReporters.

  3. sealed abstract class Kind extends AnyRef

    Describes the kind of operation being represented by a Span.

  4. case class Link(kind: Link.Kind, trace: Trace, spanId: Identifier) extends Product with Serializable

    Represents a connection between two different Spans that might belong to different traces.

  5. final class Local extends Delayed

    A writable Span created on this process and implementing all the capabilities defined by the Span interface.

  6. case class Mark(instant: Instant, key: String) extends Product with Serializable

    Represents an event that happens at a given instant and is related to a Span.

    Represents an event that happens at a given instant and is related to a Span. The key is a unique identifier of the type of event being associated.

  7. sealed abstract class Position extends AnyRef

    Describes a Span's position within the trace they belong to.

  8. final case class Remote(id: Identifier, parentId: Identifier, trace: Trace) extends Span with Product with Serializable

    A immutable, no-op Span that holds information from a Span that was initially created in another process and then transferred to this process.

    A immutable, no-op Span that holds information from a Span that was initially created in another process and then transferred to this process. This is the minimal representation of a Span that gets transferred through Context propagation channels. A remote Span completely ignores all writes made to it.
