This is a Bug Report

Problem:
f9ff985 replaced the link for "Summary API" at https://kubernetes.io/docs/reference/instrumentation/node-metrics/#psi. The new link doesn't lead anywhere. It's unclear what was the purpose of the change, the kubelet config API does not provide the Summary API.

Proposed Solution:
Either fix the link to a proper location in the docs or revert the link destination change.

Page to Update:
