io.helidon.tracing.jaeger.JaegerTracerBuilder
All Implemented Interfaces:
Builder<JaegerTracerBuilder,Tracer>, TracerBuilder<JaegerTracerBuilder>, Supplier<Tracer>
public class JaegerTracerBuilder extends Object implements TracerBuilder<JaegerTracerBuilder>
The JaegerTracerBuilder is a convenience builder for Tracer to use with Jaeger.

Unless You want to explicitly depend on Jaeger in Your code, please use TracerBuilder.create(String) or TracerBuilder.create(io.helidon.config.Config) that is abstracted.

The Jaeger tracer uses environment variables and system properties to override the defaults. Except for protocol and service these are honored, unless overridden in configuration or through the builder methods. See Jaeger documentation for details.

The following table lists jaeger specific defaults and configuration options.
