Arkamar contributed to the ktsaou/netdata repository by developing and optimizing database monitoring features for MySQL and MariaDB using Go and SQL. Over three months, Arkamar implemented InnoDB redo log occupancy monitoring and dashboards, enabling deeper analysis of storage engine performance and supporting proactive capacity planning. They enhanced the MySQL collector by introducing timestamp-based guards to prevent redundant global variable collection, improving efficiency and reliability. Additionally, Arkamar delivered InnoDB OS Log IO metrics for MariaDB 10.8+, ensuring continued visibility into critical storage subsystems during version upgrades. The work demonstrated a strong focus on performance analysis, system monitoring, and robust instrumentation.

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.
