Trace Span logs not appended to the loggers

[rajesh-giriyappa]

HI,

Trace Logs are not appended in the logger file below is my configurations

opentracing.spring.web.client.enabled=true
opentracing.spring.cloud.log.enable=true
opentracing.zipkin.enabled=true
opentracing.zipkin.http-sender.url=http://localhost:9411
opentracing.zipkin.counting-sampler.rate=1.0

@bean
public io.opentracing.Tracer globalTracer(){

    zipkin2.reporter.okhttp3.OkHttpSender okHttpSender = zipkin2.reporter.okhttp3.OkHttpSender.newBuilder()
            .encoding(Encoding.JSON)
            .endpoint("http://localhost:9411/api/v2/spans")
            .build();

    //zipkin2.reporter.brave.AsyncZipkinSpanHandler handler = zipkin2.reporter.brave.AsyncZipkinSpanHandler.create(okHttpSender);
    AsyncReporter<Span> reporter = AsyncReporter.builder(okHttpSender).build();

    brave.Tracing braveTracer = Tracing.newBuilder()
            .localServiceName(serviceName)
            .spanReporter(reporter)
            .addSpanHandler(new Log4jSpanHandler())
            .traceId128Bit(true)
            .sampler(Sampler.ALWAYS_SAMPLE)
            .build();
    return BraveTracer.create(braveTracer);
}

Above is my configurations the Spans are getting reported into Zipkin but those are not appended in the SLF4J Logs

Please could you let me know what setting need to be done to span logs append working...

By default JaegerTracer created with ThreadLocalScopeManager, but Logback seems require MDCScopeManager to work. You can change that with customizer:

@Configuration
public class JaegerTracerConfig {

    @Bean
    public TracerBuilderCustomizer scopeManagerCustomizer() {
        return builder -> builder.withScopeManager(new MDCScopeManager.Builder().build());
    }
}

I don't know how this will affect Spring Cloud tracing through...
