Systems Management Improvements
The Performance Toolkit for VM has been enhanced in z/VM V5.1 to provide functional equivalence to the Perfor- mance Reporting Facility (PRF) priced, optional feature, thereby virtually eliminating the need for separate products
(PRF and RealTime Monitor (RTM)) to help manage your performance more effi ciently. Other new function includes
•
•New reports for SCSI disks
•Support for application monitor records created by SLES 9 with the PTF for APAR VM63580
Note: Delivery of equivalent function to PRF in the Performance Toolkit for VM satisfi es the Statement of Direction made on May 13, 2003 to remove the RTM and PRF features in a future release of z/VM. The RTM and PRF features have been withdrawn from z/VM V5.1. These features are still available with z/VM V4.4 but cannot be licensed with z/VM V5.1.
