Elastic Search Version: 7.3.1  
APM Server Version: 7.3.1  
APM Client Version: 1.9.0

I am running APM Client agent along with Spring Boot based microservices. APM Client is able to instrument and able to collect traces, metric errors.

As part of the distributed tracing, i also wanted to trace.id and transaction.id in micro service logs. Our spring boot micro services use SLF4j and Logback.

I am using the property elastic.apm.enable\_log\_correlation=true to enable logging.

[https://www.elastic.co/guide/en/apm/agent/java/current/config-logging.html](https://www.elastic.co/guide/en/apm/agent/java/current/config-logging.html)

Logback configuration as follows

 { "trace.id" : "%X{trace.id}", "transaction.id" : "%X{transaction.id}" } 

But these configuration does not print any values for trace.id and transaction.id in my logs.

Is there dependency which i need to add to my spring boot project?

Hi and welcome to the forum!

We will need much more info in order to know what is not working, like- the full configuration, the agent log in debug/trace levels, what _does_ work (eg can you get other MDC data printed to your logs) etc.

However, before all that, check out [this new project](https://github.com/elastic/java-ecs-logging) which allows for automatic logging of ECS-compatible JSON that include these APM data.  
We will love your feedback on it.
