That is definitely not how to implement it. You should get the LoggerConfig that matches your parent logger and call setLevel on that. Then loop through all the loggerConfigs that start with the located LoggerConfigs name and then call setLevel on them. You typically aren’t going to have many LoggerConfigs while you could have thousands of Loggers, which all resolve to the same LoggerConfig.
