Cluster % CPU Requested is the % of the Cluster's overall CPU capacity assigned to a specific resource across the reporting period. For example, on a given day in a cluster with 24 CPU hours, if a set of containers were requested and allocated 12 CPU hours, the Cluster % CPU for that container would be 50%"
The measure itself is calculated via -
(CPU Requests per Category/Sum of Available CPU across all selected Categories) * 100
This answers how Cluster % CPU requested is calculated within the CloudHealth Platform currently.
