Dropwizard Admin: Change loglevel for all

Question

My config is the standard

logging:

  # The default level of all loggers. Can be OFF, ERROR, WARN, INFO, DEBUG, TRACE, or ALL.
  level: INFO

  # Logger-spec         


        

Answer 1

I've checked the source code for the log-level task and its main logic is implemented like this:

for (String loggerName : loggerNames) {
    ((LoggerContext) loggerContext).getLogger(loggerName).setLevel(loggerLevel);
    output.println(String.format("Configured logging level for %s to %s", loggerName, loggerLevel));
    output.flush();
}

So the way it's implemented is based on the name for the logger, knowing this I went into the source for org.slf4j.Logger interface and found this field:

String ROOT_LOGGER_NAME = "ROOT";

Doing a POST like this solved it for me:

curl -X POST -d "logger=ROOT&level=DEBUG" localhost:8081/tasks/log-level
