NOTE: On Jan 13, 2007 we discovered a date check that causes
an abend. PERF520 PACKMOD on the fromibm testcase site has a
temporary solution for FL520 that avoids the abend. There is also
PERFxxx PACKMOD files there to cover the other Perfkit releases.
APAR VM64152 will address this problem.
We apologize for any inconvenience.
APAR VM64152 is CLOSED, see LATEST SERVICE on this page for
corrresponding PTF.

VM Performance Toolkit overview
The Performance Toolkit for VM provides enhanced capabilities for a z/VM
systems programmer, system operator, or performance analyst to monitor
and report performance data. Offered as a priced optional feature of
z/VM, the Performance Toolkit for VM is derived from the FCON/ESA
program (5788-LGA), which was not available in all countries.
Use the Performance Toolkit to reduce data from the z/VM MONITOR and
produce reports and history files.
VM Performance Toolkit functions
The functions provided by the Performance
Toolkit for VM
include:
- Operation of the system operator console in full-screen mode
- Management of multiple z/VM systems (local or remote)
- Post-processing of Performance Toolkit for VM history files and VM
monitor data captured by the MONWRITE utility
- Viewing of performance monitor data using either Web browsers or PC-based
3270 emulator graphics
- TCP/IP performance reporting
VM Performance Toolkit enhancements by release
IBM introduced the Performance Toolkit for VMTM
in the announcement of z/VM V4.4
to provide a variety of reports on system performance.
With z/VM V5.1,
Performance Toolkit for VM provided functional equivalence to the
Performance Reporting Facility (PRF) priced optional feature, thereby
eliminating the need for separate products (PRF and RTM) to help manage
your performance more efficiently. This included a new BATCH mode of
processing monitor data.
Product enhancements are discussed in this White Paper:
"What's new in Performance Toolkit for VM in z/VM V5.1"
 .
Other function provided with z/VM V5.1 included:
- New high-level Linux reports based on Application Monitor records
from Linux guests
- A new report for SCSI disks
Function added with with z/VM V5.2
for Performance Toolkit for VM:
- Support for updated control blocks and new monitor data
- Handle changes to offsets in CP Control blocks
- Handle fields removed from CP Control blocks
- New System Execution Space report
- New System Storage reporting
- Eliminate Detailed User Storage report
- Expand QDIO report based on new Monitor Data
For z/VM V5.3, Performance Toolkit for VM is being
upgraded to a new function level (FL530) and includes:
- Support passphrases when accessing the Performance Toolkit using the Web
interface
- Change the service process for Performance Toolkit from a full-part
replacement MODULE to service by individual object parts, reducing
the size of the service deliverable
- Provide new or updated displays and reports to support the following new
z/VM V5.3 functions:
- Linux monitor data for virtual CPUs and steal time counters
- Monitor data for virtual network devices and virtual switches
- Monitor data for guest simulation of zAAPs, zIIPs, and IFLs
- Monitor data for up to 32 processors in a z/VM image
- Change to a dump readable by the Dump Viewing Facility
In addition to analyzing VM performance data, the Performance Toolkit
for VM
processes Linux performance data obtained from the Resource Management
Facility (RMFTM) Linux performance gatherer, rmfpms.
The rmfpms application is available from the
zSeries RMF Web site.
The Linux performance data
obtained from RMF can be viewed and printed
similarly to the way VM data is presented.
Getting started
Get started with Performance Toolkit for VM with
this new Redbook:
Linux on IBM
zSeries and S/390: Performance Toolkit for VM
If you will be supporting Linux instances on z/VM,
consider attending one of the
new course offerings from IBM Learning Services.
Considerations for RTM and PRF
Although the RealTime Monitor (RTM) and Performance Reporting Facility
(PRF)
optional features continue to be supported in z/VM 4.4.0, IBM plans to make
future
performance management enhancements primarily to the Performance Toolkit
for
VM.
IBM plans that z/VM 4.4.0 will be the last release in which the RTM and
PRF features will be available with z/VM, and plans to withdraw both
the RTM and PRF
features from marketing in a future z/VM release.

RTM function cross reference
VMPRF report cross reference
The Performance Toolkit for VM feature is considered to be a program
update for the RTM and PRF features as defined in the z/VM Addendum for
Support, Z125-6547.
Therefore, any existing z/VM V4 customers who have purchased a
Subscription & Support
(S&S) license for the RTM or PRF feature are entitled to receive a
no-charge upgrade to
the Performance Toolkit for VM feature when ordering z/VM V5:
Refer to the announcement letters for details:
z/VM V5.1
z/VM V5.2
z/VM V5.3
