spanName - The name of the returned Span.

Returns:

a Span.Builder to create and start a new Span.

getInstrumentationScopeInfo

InstrumentationScopeInfo getInstrumentationScopeInfo()

isEnabled

public boolean isEnabled()

Description copied from interface: ExtendedTracer

Returns true if the tracer is enabled.

This allows callers to avoid unnecessary compute when nothing is consuming the data. Because the response is subject to change over the application, callers should call this before each call to Tracer.spanBuilder(String).
