Package com.linkedin.alpini.log

Class FastLogContextFactory

  • All Implemented Interfaces:
    org.apache.logging.log4j.spi.LoggerContextFactory
    public final class FastLogContextFactory
extends java.lang.Object
implements org.apache.logging.log4j.spi.LoggerContextFactory
    An alternate Log4j2 LoggerContextFactory implementation which returns loggers which can short-circuit debug and trace messages so that they may be disabled without incurring cost from filters installed within Log4j. This may be installed by specifying -Dlog4j2.loggerContextFactory=com.linkedin.alpini.log.FastLogContextFactory It should install a management mbean com.linkedin.alpini.log:type=FastLog which will allow enabling DEBUG/TRACE propagation.
