Controlling Hierarchical Logging with SLF4J and Logback

Couchbase Server, a complex enterprise software product, utilizes SLF4J for logging, which can integrate with frameworks like Java's java.util.logging, log4j, and logback. The author developed a sample application using the Couchbase Multi-Cluster Aware Java client, highlighting its ability to seamlessly handle node failover. They chose to use logback for its advanced capabilities and provided a Maven dependency for easy integration. The author aimed to refine the logging output, particularly to focus on network connectivity issues, and introduced a logback configuration file to hierarchically control logging levels. This configuration allows setting different logging levels for various classes within the Couchbase Server, enabling a more targeted and less noisy logging experience. The post encourages exploring Couchbase's open-source offerings, providing further resources and support channels for developers.
