How to remove appender from logger in log4j2 programmatically?

Question

Is there any way I can remove appender from a logger in log4j2 programmatically ?

The website says "Log4j 2 API does not expose methods to add, modify or remove appenders and filters or manipulate the configuration in any way" : https://logging.apache.org/log4j/2.x/manual/configuration.html

But i would really appreciate if someone can suggest an indirect way to achieve this.

Thanks.

Answer 1

Developing an idea of Anton (on log4j 2.11.1):

LoggerContext context = LoggerContext.getContext(false);
Configuration configuration = context.getConfiguration();
LoggerConfig loggerConfig = configuration.getLoggerConfig("loggerName");
if (loggerConfig.getName().equals("loggerName")) {
    loggerConfig.removeAppender("appenderName")
} else {
    throw new RuntimeException("There was no logger " + "loggerName");
}
context.updateLoggers();

Answer 2

There is a method LoggerConfig#removeAppender(String name) which will remove specific appender and LoggerConfig#clearAppenders() which will remove all appenders. Let's say you have an appender with the name CONSOLE:

final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
final Configuration config = ctx.getConfiguration();
config.getRootLogger().removeAppender("CONSOLE");
ctx.updateLoggers();
