Element Details

Returns:

span name

Default:

"%1$s.%2$s"

kind

Span.Kind kind

Span kind. Defaults to Span.Kind.INTERNAL. Note that if kind is set on a type to anything else than internal, it cannot be changed to internal on method level (i.e. internal is default, so we use the value from parent).

If a method needs to use internal span kind, there must not be a type Tracing.Traced annotation.

INTERNAL
