Extracting Resource Allocation Data for Chargeback in a HP Virtual Server Environment for HP Integrity Servers

Workload Allocation Information

For nPar and vPar workloads, the CPU core utilization of the workload reported by Capacity Advisor

is the combined user and system time as seen by the OS running in the partition. This utilization

typically is less than 100% of the cores that VSE allocates to the partition.

GUI: Capacity Advisor Utilization Report

The Capacity Advisory Utilization Report includes a summary table for partitions of a complex

physical server. The CPU Count column is actually the average number of physical CPU cores

allocated to the partition over the reporting period, as shown in the following example:

In this example, the CPU count is not a whole number because the nPars are under the control of

gWLM, which is dynamically activating and deallocating TiCAP processing.

CLI: capreport tool

As described earlier, the capreport tool creates a subdirectory and files of an XML report for the

utilization of a collection of workloads. The index.html file for the report includes the average

physical CPU core allocation for the workload in the CPU Count column. For example:

CMS # pwd

/tmp/2007-10-3-105329-612/CapAdReport

CMS # more index.html
