Have you set up a logging and journaling system in your projects?

Yes, I have configured log management and logging systems. The process usually includes:

• Choosing an appropriate tool (for example, ELK Stack — Elasticsearch, Logstash, Kibana; or Fluentd, Graylog).
• Setting up logging in applications using libraries (Log4j, SLF4J for Java, Winston for Node.js, etc.).
• Centralizing logs with agents or services to collect logs from all components in one place.
• Configuring log rotation and storage to manage data volume.
• Organizing log search and visualization for quick analysis and debugging.

Example of logging setup in Java with Log4j:

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Example {
    private static final Logger logger = LogManager.getLogger(Example.class);

    public static void main(String[] args) {
        logger.info("Application started");
        try {
            // code
        } catch (Exception e) {
            logger.error("Execution error", e);
        }
    }
}
