Chapter 8. Logging subsystem tuning

Disabling console logging can improve JBoss EAP performance. Although outputting logs to the console can be useful in development and testing environments, for production environments, in most cases, it is not necessary.

The JBoss EAP root logger includes a console log handler for all default standalone server profiles except standalone-full-ha. The default managed domain profiles do not include a console handler.

For ideal performance, ensure that you configure the logging levels for your production environment appropriately. For example, although INFO or DEBUG levels might be appropriate for development or testing environments, in most cases you should set your production environment logging level to something higher, such as WARN or ERROR.

You should consider the storage location of log files as a potential performance issue. If you save logs to a file system or disk configuration that has poor I/O throughput, it has the potential to affect the whole platform’s performance.

To prevent logging from impacting JBoss EAP performance, set your log locations to high-performance dedicated disks that have a lot of space.
