December 2024 monthly summary for the developer work: Key features delivered: - Container Metrics Data Point Cap introduced to store only the latest 300 data points for container metrics (CPU, memory, and I/O pressure). Implemented via a new constant metricsMaxItemsCount and enforced at the data aggregation layer, improving performance and reducing memory usage. Major bugs fixed: - No major bugs fixed this month. Focus was on delivering a performance-oriented feature and ensuring stability of the metrics path. Overall impact and accomplishments: - Improved dashboard responsiveness and scalability for container metrics, with lower memory footprint and more predictable performance under load. - Enhanced data reliability for metrics dashboards by bounding historical data to a fixed-size window. - Strengthened traceability from NAS ticket to code changes (NAS-132758) via the commit referenced below. Technologies/skills demonstrated: - Data aggregation optimization and constant-driven configuration (metricsMaxItemsCount). - Version control discipline and ticket traceability (commit NAS-132758 / 25.04, hash 036fc6c833b8018aaeea3bd46bfef76d9c1ea1fd). - Focus on performance and scalability within the TrueNAS WebUI context.
