I am working on a demo project to enable distributed tracing on logs. I initially started with sleuth, but later on figured out that it is being migrated to micrometer(Sleuth is not compatible with spring boot 3.x)
But out of my surprise I am not able to see traceId and spanId in logs in my console.
Changes I have done.
Added dependency in pom.xml
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-tracing-bridge-brave</artifactId>
<version>1.1.1</version>
<exclusions>
<exclusion>
<groupId>io.zipkin.brave</groupId>
<artifactId>brave</artifactId>
</exclusion>
</exclusions>
</dependency>
Excluded io.zipkin.brave as it was causing a dependency conflict.
Added a consoleAppender on logback.xml
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
+ <encoder>
+ <Pattern>
+ %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} [%X{X-B3-TraceId},%X{X-B3-SpanId}] - %msg%n
+ </Pattern>
+ </encoder>
+ </appender>
I have created a test controller:
@GetMapping("/log/test")
public ResponseEntity<String> test()
{
log.info("Inside test");
return ResponseEntity.ok("Done");
}
When I am trying to hit this controller I am not getting traceId in logs. sample log:
2023-06-20 18:19:31.649 [http-nio-8090-exec-2] INFO a.b.c.TestController [,] - Inside test
As per my understanding mdc puts the traceId and spanId directly in log lines. I am confused what I am missing here.
Any help will be highly appreciated.
