Handlers are the core components that deal with logging events. We will go through the handlers that are available on the EAP and how to create new loggers to keep the server logs separate from the application logs.

In the following section, we will first cover the handlers, starting with the default ones provided in the configuration, and then look at how to create custom handler configurations.
