Log Helper

log-helper configures console log to include additional fields for traceability purposes.

• spring.application.name, make sure to configure it in bootstrap.properties.
• traceId and spanId from Spring Cloud Sleuth.
• Extra field from HTTP header. By default, it propagates correlationId.

Note: log-helper uses Log4j2.

   <dependency>
