Airlock IAM uses Log4j to create log messages for IAM. Up to Airlock IAM 7.7, Log4j WebLookups have been used to include the name of the logging IAM module (e.g. Adminapp or Transaction Approval) in the log messages.
With Airlock IAM 8.0 and later, Log4j WebLookups are no longer supported by Log4j. As a replacement, the IAM module name is now part of the Log4j configuration files.
When migrating the IAM configuration to 8.0, the upgrade process can automatically migrate the Log4j configuration files in most cases. If the logging configuration is customized, the migration may fail or be incomplete and has to be fixed manually.
This article describes how to check if the migration has been successful and what to do if the automatic migration fails.
