How can you send logs to an external logger?

• A. With an additional appender in log4j
• B. By modifying the OS logging subsystem
• C. By using a dedicated HTTP endpoint from the runtime
• D. It is not possible to send logs externally

Answer: (A)

Logging events are routed to destinations via appenders in the logging framework. To send logs to an external logger, you add an additional log4j appender that forwards the log events to the external system. This lets you centralize logs without changing application code or the runtime’s core behavior, and you can choose from built-in appenders like Syslog or HTTP, or use a custom one if needed. Modifying the OS logging subsystem won’t affect how the application’s logs are emitted, and while a dedicated HTTP endpoint could work, it requires a matching appender setup—rather than being the standard out-of-the-box method. Saying external logging isn’t possible isn’t accurate because appenders are designed exactly for this purpose.
