How can I configure Log4j2 for advanced logging features?

You can configure Log4j2 using XML, JSON, or YAML configuration files. What specific features are you interested in?

I want to set up asynchronous logging and custom log levels.

For asynchronous logging, you can use the AsyncAppender. To set custom log levels, you can define them in your configuration file. Would you like an example?

Yes, please provide an example configuration.

Here's a simple XML configuration for asynchronous logging:

<Configuration>
    <Appenders>
        <Async name="AsyncLogger">
            <AppenderRef ref="Console" />
        </Async>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1} - %m%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="AsyncLogger" />
        </Root>
    </Loggers>
</Configuration>
