shown earlier.
Other logging systems have to configure their own formatter to get the same result.
The default is as follows:
<code>logging.pattern.level</code> set to <code>%5p [${spring.zipkin.service.name:${spring.application.name:-}},%X{traceId:-},%X{spanId:-},%X{spanExportable:-}]</code>
<code>logging.pattern.level</code> set to <code>%5p [${spring.zipkin.service.name:${spring.application.name:-}},%X{traceId:-},%X{spanId:-}]</code>
(this is a Spring Boot feature for logback users).
If you do not use SLF4J, this pattern is NOT automatically applied.
