14.4.1. About Per-deployment Logging
Per-deployment logging allows a developer to configure in advance the logging configuration for their application. When the application is deployed, logging begins according to the defined configuration. The log files created through this configuration contain information only about the behavior of the application.
This approach has advantages and disadvantages over using system-wide logging. An advantage is that the administrator of the JBoss EAP instance does not need to configure logging. A disadvantage is that the per-deployment logging configuration is read only on startup and so cannot be changed at runtime.
