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.
