Developed enhanced resource monitoring capabilities for the temporalio/sdk-core repository by implementing cgroup v2 CPU usage calculation with a sysinfo-based fallback to ensure accurate metrics when cgroup data is unavailable. This work included comprehensive unit tests for both CPU and memory reading from cgroups, improving reliability and test coverage. The developer also upgraded the CI/CD pipeline to support cross-compiling and automated testing within Docker containers, streamlining the build process across diverse environments. The project leveraged Rust, Shell scripting, and Docker, demonstrating a focus on robust system programming, resource management, and automated testing practices within a modern continuous integration workflow.
