Description

Very useful to be able to change the log levels for any logger (i.e. class or package) at runtime in a long lived server process.
Usually an arbitrary class will not have its own logger configured already so need to create one on the fly in order to specify its log level without everything else picking it up.

Example simple implementation of a util I created for this attached.
Takes a loggerName and level and either updates level if existing logger, or configures a new logger using parent appenders if new.
Not sure where it would best live - possibly org.apache.logging.log4j.core.jmx.LoggerContextAdmin
