Chapter 10. Distributed tracing
Chapter 10. Distributed tracing The client offers distributed tracing based on the Jaeger implementation of the OpenTracing standard. 10.1. Enabling distributed tracing Use the following steps to enable tracing in your application: Procedure Add the Jaeger client dependency to your POM file. <dependency> <groupId>io.jaegertracing</groupId> <artifactId>jaeger-client</artifactId> <version>USD{jaeger-version}</version> </dependency> USD{jaeger-version} must be 1.0.0 or later. Add the jms.tracing option to your connection URI. Set the value to opentracing . Example: A connection URI with tracing enabled Register the global tracer. Example: Global tracer registration import io.jaegertracing.Configuration; import io.opentracing.Tracer; import io.opentracing.util.GlobalTracer; public class Example { public static void main(String[] args) { Tracer tracer = Configuration.fromEnv(" <service-name> ").getTracer(); GlobalTracer.registerIfAbsent(tracer); // ... } } Configure your environment for tracing. Example: Tracing configuration USD export JAEGER_SAMPLER_TYPE=const USD export JAEGER_SAMPLER_PARAM=1 USD java -jar example.jar net.example.Example The configuration shown here is for demonstration purposes. For more information about Jaeger configuration, see Configuration via Environment and Jaeger Sampling . To view the traces your application captures, use the Jaeger Getting Started to run the Jaeger infrastructure and console.
