public OpencensusTracerFactory(Map<String,String> spanAttributes)

Instantiates a new instance capturing the 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.

Parameters:

spanAttributes - the attributes to stamp on every span. Should include things like library version.

Method Details

newTracer
