16.2.4 Viewing and setting logging level

The Actuator’s /loggers endpoint is helpful in understanding and overriding logging levels in a running application. The Admin server’s Loggers screen adds an easy-to-use UI on top of the /loggers endpoint to make simple work of managing logging in an application. Figure 16.8 shows the list of loggers filtered by the name org.springframework.boot.。

Figure 16.8 The Loggers screen displays logging levels for packages and classes in the application and lets you override those levels.

By default, the Admin server displays logging levels for all packages and classes. Those can be filtered by name (for classes only) and/or logging levels that are explicitly configured versus inherited from the root logger.
