If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

The oc get apirequestcounts command can be used to return the list of API's and their current request counts.

~]# oc get apirequestcounts

Often, you'll want to review this output before upgrading OpenShift to a new version to determine if any of the APIs have been removed in the version of Kubernetes you are upgrading to. The oc version command can be used to list the version of Kubernetes you are currently at (1.24 in this example). In this example, if you are going to be upgrading OpenShift that includes Kubernetes 1.25 the APIs listed above would be removed since the APIs are being removed in Kubernetes version 1.25. You probably would only be concerned with the APIs that have requests in the last 24 hours.

~]$ oc version
Client Version: 4.12.25
Kustomize Version: v4.5.4
Server Version: 4.12.25
Kubernetes Version: v1.24.6+5658434
