Ralph Goers commented on LOG4J2-3382:
-------------------------------------

We are aware of this issue. The workaround for now is to move the ThreadContext variable reference to the filePattern.

> Added to the MDC in Java:
> {{org.slf4j.MDC.put("txLogRecordType", eventType);}}
> The file produced now looks like:
> {{myservice_transaction_${ctx.txLogRecordType}_2022-01-27-16.log}}
> Prior to upgrading to log4j2 2.17.0, this interpolated as expected.
> Have also tried myserver_transaction_%X\{txLogRecordType}.log, but gives similar output file.
