what should I do to add new tags in sleuth, such as client ip address, I want to add the client ip address in logs, of course, with traceId, spanId

Question

I am trying to finish a log system, which is to monitor a spring cloud application. The spring-cloud application consists of several microservices, using sleuth for distributed tracing. I have set the pattern of log, and now there are tags like 'traceId', 'spanId', 'parentId' in the log. Now , I would like to add a new tag named 'client_ip' into the log. How can I make it ? And how to pass the client_ip tag to downstream microservice. Currently, my plan is to get client ip in api-gateway service.

I'm not sure if this has anything to do with Sleuth. You can modify your log settings and add what you want. Sleuth modifies the level in the pattern ( logging.pattern.level ) and adds these details there.
