I will explain in detail what are those keyword (log levels, appender, and log format)

Logging Levels: Log4j supports multiple logging levels, including DEBUG, INFO, WARN, ERROR, and FATAL. Developers can choose the appropriate level based on the severity of the message they want to log.

Configurability: Log4j allows developers to configure logging behavior through configuration files (such as XML or properties files) or programmatically. This configuration includes settings for logging levels, log file appenders, log formats, and more.

Appenders: Log4j uses the concept of "appenders" to specify where log messages should be outputted. Common appenders include the console appender, file appender, rolling file appender, SMTP appender (for sending emails), and more. Developers can also create custom appenders as needed.

In Log4j 2, the (Appender) tag is used to define the destination or output location for log messages. Appenders specify where log events should be written, such as to the console, a file, a database, or a network socket.

PatternLayout is a key component of the Log4j logging framework that allows developers to define the format of log messages.
