The zCP3000 VM Extract Utility (CP3KVMXT) summarizes VM monitor data into a
stuctured but readable file. The intended use is to create an input file to
the IBM zCP3000 Capacity Planning tool. The CP3KVMXT utility
- accepts as input either realtime monitor data or saved monitor data
- accumulates CP intervals into longer, user-defined measurement periods.
- supports the use of a VMPRF-like UCLASS file for grouping users into
workloads
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. For detail on how to run the utility, please download the user's
guide included in the VMARC package, or see it online at
