Class SamplingLogger

java.lang.Object

alluxio.util.logging.SamplingLogger

All Implemented Interfaces:

org.slf4j.Logger

public class SamplingLogger
extends Object
implements org.slf4j.Logger

A logger which limits log message frequency to prevent spamming the logs. After the logger logs a message, it enters a configurable cooldown period where it will ignore repeated logging requests with the same message. Messages are compared by message template, not message arguments.
