56. Loggers

Spring Boot Actuator includes the ability to view and configure the log levels of your application at runtime. You can view either the entire list or an individual logger’s configuration, which is made up of both the explicitly configured logging level as well as the effective logging level given to it by the logging framework. These levels can be one of:

null indicates that there is no explicit configuration.

56.1 Configure a Logger

To configure a given logger, POST a partial entity to the resource’s URI, as shown in the following example:

	"configuredLevel": "DEBUG"

To “reset” the specific level of the logger (and use the default configuration instead), you can pass a value of null as the configuredLevel.
