Metrics Server

Metrics Server is a Kubernetes component that collects resource usage data in the cluster and sends it to other Kubernetes components via the Metrics API. Horizontal Pod Autoscaling and Vertical Pod Autoscaling rely on data from Metrics Server. You can view metrics using kubectl top. Autoscaling of node groups on cloud servers can be configured using Cluster Autoscaler. For monitoring, see logs in your Managed Kubernetes cluster or use dedicated applications, for example, Prometheus.

Metrics Server is installed by default in Managed Kubernetes clusters of version 1.27 and higher. You can upgrade the cluster version.
