* Logger Name

 Logger name is basically the classical fully qualified class name: it's not visible by default, but can be activated (see {{{/maven-logging.html}user documentation}}).

 Notice that before Maven 3.1.0, with logger created by Maven, some code used to pass logger from class to class because it could not create a new logger:

                if (response.getHttpStatusCode() == 200) {
                    logger.info("Register {} to {}", path, indexName);
                    return true;
                }
                logger.warn("Invalid request for {}", path);
            }
        } catch (final Exception e) {
            logger.warn("Failed to register {}", filePath, e);
        }
        return false;
    }

import org.slf4j.Logger;
import org.slf4j.helpers.NOPLogger;

public enum WatchMode {
    ENABLED(true, "enabled") {
        @Override
        public Logger loggerForWarnings(Logger currentLogger) {
            return currentLogger;
        }
    },
    DEFAULT(true, "enabled if available") {
        @Override
        public Logger loggerForWarnings(Logger currentLogger) {

func getIndexFailureCount(logger klog.Logger, pod *v1.Pod) int32 {
	return parseIndexFailureCountAnnotation(logger, pod)
}

func getIndexAbsoluteFailureCount(logger klog.Logger, pod *v1.Pod) int32 {
	return parseIndexFailureCountAnnotation(logger, pod) + parseIndexFailureIgnoreCountAnnotation(logger, pod)
}

func parseIndexFailureCountAnnotation(logger klog.Logger, pod *v1.Pod) int32 {

                            if (logger.isDebugEnabled()) {
                                logger.debug("generator path: {}", filePath);
                            }
                            return filePath;
                        }
                    }
