PROFILE
Raj Zalavadia
Rohit Zalavadia developed and enhanced right-sizing analytics and observability features for the stolostron/multicluster-observability-operator repository over five months. He engineered namespace and cluster resource utilization dashboards in Grafana, integrating CPU and memory metrics using Go and Prometheus to improve capacity planning and data accuracy. Rohit refined Prometheus queries for precise cross-cluster aggregation, optimized dashboard performance with instant-time metric evaluation, and adapted metrics collection to namespace scope for CI reliability. His work included policy enforcement, dashboard configuration refactoring, and data-quality improvements, resulting in more reliable resource recommendations, streamlined operational workflows, and increased trust in observability data for both CI and production environments.

Dec 1, 2025December 2025: Delivered enhancements to the right-sizing dashboards for the multicluster-observability-operator, improving data accuracy and reliability for capacity planning. Implemented CPU and memory metric integration for cluster dropdown data, updated the virtual CPU request query for consistency with existing dashboards, switched to kubevirt_vmi_vcpu_seconds_total for CPU data, and adapted metrics collection to namespace-scoped data to accommodate CI limitations. These changes reduce estimation errors, streamline resource planning, and strengthen dashboard trust in CI and production environments.

Jun 1, 2025June 2025 performance summary for stolostron/multicluster-observability-operator. Key deliveries focused on visualization accuracy, data correctness, and operational efficiency. Highlights include: Grafana dashboard refactor for ACM right-sizing with dynamic datasource UIDs, color theme alignment, and correct Instant data point typing; improved Prometheus query accuracy by ensuring cluster-level sums are considered before applying max_over_time; optimized MCOA status checks to exit early when core platform capabilities are disabled, reducing unnecessary processing and ensuring status reflects essential features. These changes enhance maintainability, reliability of resource recommendations, and system efficiency, translating to improved business value in capacity planning, faster status propagation, and lower compute overhead.
