Which log4j level is the least verbose and disables logging when set?

Explanation:
Off is a special log4j level that tells the system to emit no log messages at all. It’s the least verbose because nothing gets logged, regardless of the message’s severity. When a logger is set to a level like DEBUG, INFO, or WARN, messages at that level and above will be written. For example, DEBUG would include DEBUG, INFO, WARN, ERROR, and FATAL, whereas OFF stops all of them from being emitted. This makes OFF the way to completely disable logging.
