This patch introduces a whitelist-based label filtering mechanism in cadvisor/kubelet metrics collection. By explicitly keeping only the desired labels, we avoid noisy and high-cardinality dimensions while retaining meaningful CPU metrics for analysis. This improves the stability of the metrics pipeline and ensures consistent visibility into application workloads. ```release-note [monitoring] Introduce whitelist label filtering for cadvisor/kubelet metrics to reduce noise and improve CPU metric reliability. ``` |
