Currently we run this job weekly - https://master-jenkins-csb-servicemesh.apps.ocp-c1.prod.psi.redhat.com/job/infra/job/psi-usage-report/

It generates email with list of VMs and resources usage.

There is a room for improvements:

• show more user friendly statistics - percentage, etc.
• mark visibly VMs which are older than one week
• improve overall readability
