Couchbase Server 6.5 introduces significant updates to its statistics display in the Web Console, enhancing their utility for performance monitoring and troubleshooting in large production systems. The new features include intelligent line charts with labeled axes that are adaptable to various screen sizes, customizable dashboards, and the ability to aggregate node data for more efficient analysis. Users can select specific time ranges, toggle data feeds, and create personalized scenarios using the chart builder, which allows for the combination of different stats, services, and nodes. Additionally, service-specific stats are now integrated inline with corresponding lists, and the design accommodates scalability for large collections of data, particularly in services like Indexing. These improvements aim to provide greater visualization and clarity, facilitating quicker resolution of issues and better overall system management.
