KubernetesThe root cause of this issue originates in Kubernetes

How to detect:

Monitor kubecost_cluster_efficiency_ratio metric via Prometheus. Set alerts when efficiency falls below 0.5 (50%). Review Kubecost Health dashboard for resource utilization patterns across nodes and pods.

Recommended action:

Investigate underutilized nodes and consider node consolidation. Review pod resource requests for over-provisioning. Implement horizontal pod autoscaling for variable workloads. Consider using cluster autoscaler to right-size node pools. Apply container right-sizing recommendations from Kubecost.
