Red Hat Advanced Cluster Management 2.16 promotes right-sizing recommendations for namespaces and OpenShift Virtualization workloads from Tech Preview to General Availability. The feature uses Prometheus recording rules and Thanos-based aggregation to analyze long-term CPU and memory usage trends across multicluster environments, surfacing over- and under-provisioned resources via integrated Grafana dashboards. Key benefits include fleet-wide resource insight, data-driven recommendations grounded in historical time-series data, and unified visibility across containerized and virtualized workloads. The post also compares right-sizing recommendations with Vertical Pod Autoscaler, noting they complement each other: ACM provides strategic baselines while VPA handles dynamic in-flight adjustments. Getting started requires upgrading to ACM 2.16 and enabling multicluster observability.
