1.2 Metrics Server

One Metrics server is for one K8s cluster. The metrics server retrieves metrics from each of the kubernetes nodes and pods, aggregates them and stores them in memory.

Note that the metric server is only an in memory monitoring solution and does not store the metrics on the desk and as a result you cannot see historical performance data.
