Configuring a Logging Profile in JBoss EAP

JBoss Enterprise Application Platform allows us to do more than simply deploy applications — we can also manage and maintain them during their lifecycle. Part of this is the ability to log what we need when we need it, which is where JBoss EAP logging profiles come in. Logging profiles allow us to write customized logging rules that we then attach to our applications as desired.
