Developed and integrated JVM memory metrics collection into the backend of the crossoverJie/starrocks repository, focusing on enhancing system observability and operational insight. Leveraged C++ and Java to implement metrics instrumentation, introducing new source and header files for JVM metrics management and utilizing JNI for seamless integration. Added a configuration option to enable or disable JVM metrics, allowing for flexible performance tuning and reduced overhead when monitoring is not required. The work aligned with StarRocks’ observability strategy, supporting improved incident diagnosis and capacity planning. Emphasis was placed on backend service development, system metrics, and robust configuration management throughout the project.
