Sthaha contributed to the sustainable-computing-io/kepler repository, architecting and implementing a robust power monitoring and analytics platform for cloud-native and bare-metal environments. Over seven months, Sthaha rewrote core components for maintainability, introduced structured logging, and expanded observability with Prometheus and Grafana integration. Leveraging Go, YAML, and shell scripting, Sthaha engineered features such as dynamic power attribution, Redfish and RAPL integration, and VM-aware monitoring, while improving deployment flexibility through Helm and OCI registry support. The work emphasized concurrency safety, configuration management, and comprehensive documentation, resulting in a scalable, testable system that streamlines diagnostics, deployment, and power analytics for operators.

September 2025: Delivered Kepler power monitoring enhancements using Redfish PowerSubsystem with fallback to the legacy Power API, enabling on-demand, multi-chassis power visibility and a new Prometheus metric kepler_platform_watts. Also produced comprehensive OCI Helm chart deployment documentation to streamline production deployments, GitOps workflows, monitoring, and troubleshooting. No major bugs fixed this month; focus was on feature delivery, reliability, and documentation. Overall, these efforts improve observability, reliability, and deployment agility, while laying groundwork for scalable power analytics across bare-metal fleets.

2025-08 Monthly Summary for sustainable-computing-io/kepler focused on delivering architectural clarity, deployment flexibility, and improved observability. Key features delivered include comprehensive Kepler Architecture Documentation detailing system components, data flow, concurrency patterns, interfaces, and configuration management, plus an MSR fallback power meter support proposal (EP-002) to broaden deployment options when Intel RAPL is unavailable. A major bug fix improved QEMU-KVM VM detection accuracy on CentOS/RHEL/OpenStack by expanding detection patterns to include '/usr/libexec/qemu-kvm' alongside '/bin/qemu-system-*', ensuring VM metrics are captured in OpenStack deployments. Overall impact includes better onboarding, maintainability, and broader hardware coverage with more reliable metrics collection. Technologies/skills demonstrated include architecture documentation, MSR/RAPL concepts, Linux VM detection patterns, CentOS/RHEL/OpenStack deployment considerations, and cross-team documentation collaboration.
