A resource metric is a numeric quantity that tracks the value of a [[Kubernetes_Resource_Management_Concepts#Resource|resource]] specified by a Kubernetes API resource. By default, the only two supported resource metrics are the CPU utilization of a container and the memory consumed by a container. These resources do not change names from cluster to cluster and they should be available as long the Metrics API is available.

Resource Metric

A resource metric is a numeric quantity that tracks the value of a resource specified by a Kubernetes API resource. By default, the only two supported resource metrics are the CPU utilization of a container and the memory consumed by a container. These resources do not change names from cluster to cluster and they should be available as long the Resource Metrics API is available.

Custom Metric

Aside from resource metrics, there are two other types of metrics, both of which are considered custom metrics: pod metrics and object metrics.
