Initially I had such logging configuration in my spring boot 3.4 app:

logging:
  ...
  pattern:   
    file: "%d [%thread] %-5level %-50logger{40}- %n"
    console: "%d [%thread]%-5level %-50logger{40}- %n"

Then I've added tracing and trace/spanId was not added auomatically to my pattern so I've added:

  pattern:
    correlation: "[${spring.application.name:},%X{traceId:-},%X{spanId:-}]"
    file: "%d [%thread]${logging.pattern.correlation} %-5level %-50logger{40} - %n"
    console: "%d [%thread]${logging.pattern.correlation} %-5level %-50logger{40} %n"

Is there way to do it in a simpler way without explicit link to logging.pattern.correlation ?

is there smth like %thread for corellation ?

The simplest way is doing nothing, this works out of the box and logs contain the correlation IDs. Iy you override the pattern and you don't use logging.pattern.correlation in it, it will bot be there (you are explicitly asking for not to be there). See the docs: https://docs.spring.io/spring-boot/reference/actuator/tracing.html#actuator.micrometer-tracing.logging
