public final class OpencensusTracerFactory extends BaseApiTracerFactory

A ApiTracerFactory to build instances of OpencensusTracer.

This class wraps the Tracer provided by Opencensus in Tracing.getTracer(). It will be used to create new spans and wrap them in OpencensusTracer defined in gax.

This class is thread safe.

Constructors

OpencensusTracerFactory()

public OpencensusTracerFactory()

Instantiates a new instance capturing the io.opencensus.trace.Tracer in Tracing.getTracer.

OpencensusTracerFactory(Map<String,String> spanAttributes)

public OpencensusTracerFactory(Map<String,String> spanAttributes)

Instantiates a new instance capturing the io.opencensus.trace.Tracer in Tracing.getTracer. It will also override the service name of the grpc stub with a custom client name. This is useful disambiguate spans created outer manual written wrappers and around generated gapic spans.

Parameter

Name	Description
spanAttributes	`Map<String,String>` the attributes to stamp on every span. Should include things like library version.
