Worked on the ktsaou/netdata repository to enhance MySQL and MariaDB monitoring capabilities, focusing on InnoDB storage engine metrics and performance analysis. Developed Go-based collectors to monitor InnoDB redo log occupancy, OS log I/O, and checkpoint age, introducing new charts and dashboards for deeper visibility into database internals. Addressed performance by optimizing data collection routines, such as preventing redundant global variable queries and aligning test scenarios with intended MySQL versions. Leveraged Go, SQL, and system monitoring skills to ensure compatibility with MariaDB 10.8+ and support proactive capacity planning, enabling users to diagnose storage bottlenecks and maintain reliable database operations.

Feb 1, 2025February 2025 highlights: Delivered a key feature for netdata's MariaDB monitoring by adding InnoDB OS Log IO metrics for MariaDB 10.8+. Implemented collection of innodb_os_log_written and introduced a new chart, preserving innodb_os_log_written as other related variables were deprecated to maintain continuity of visibility into InnoDB OS log I/O performance for MariaDB 10.8+. The change strengthens proactive performance monitoring and supports customers upgrading to MariaDB 10.8+. This work reinforces the ongoing effort to extend visibility into critical storage subsystem metrics and reduce blind spots during version upgrades.
