=== Logging Correlation IDs
Correlation IDs provide a helpful way to link lines in your log files to spans/traces.
By default, as long as configprop:management.tracing.enabled[] has not been set to `false`, Spring Boot will include correlation IDs in your logs whenever you are using Micrometer Tracing.
When you are using Micrometer Tracing, Spring Boot will include correlation IDs in your logs.
The default correlation ID is built from `traceId` and `spanId` https://logback.qos.ch/manual/mdc.html[MDC] values.
For example, if Micrometer Tracing has added an MDC `traceId` of `803B448A0489F84084905D3093480352` and an MDC `spanId` of `3425F23BB2432450` the log output will include the correlation ID `[803B448A0489F84084905D3093480352-3425F23BB2432450]`.
