From Gretchen Frye, IBM Washington Systems Center

The zCP3000 VM Extract Utility (CP3KVMXT) summarizes VM monitor data into a stuctured but readable file describing the configuration and performance of a single z/VM partition over a period of time. The resulting EDF (Electronic Data File) is used as input for the IBM capacity planning tool zCP3000 and the IBM zPCR Processor Comparison Reference. The CP3KVMXT utility

• accepts as input either realtime monitor data or saved monitor data
• can process multiple (ie hourly LINMON) monitor files into one EDF.
• accumulates short CP intervals into longer, user-defined measurement periods.
• supports the use of a PARMS file to provide run-time paramaters.

The accumulation of CP intervals into longer "durations" makes it easier to deal with the longer time periods of performance data needed for capacity planning.

Links to download the cp3kvmxt tool, and to documentation on setting up prerequisites, collecting monitor data, and running the tool, are available in the IBM support page CP3KVMXT - VM Extract Utility CP3000 and zPCR Capacity Planning Support Tools
