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.
See the
required service in order to run z/VM and
Performace Toolkit on the new zEnterprise System
(07-2010)
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
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
z/OS RMF Web site.
The Linux performance data
obtained from RMF can be viewed and printed
similarly to the way VM data is presented.
IBM introduced the Performance Toolkit for VM
TM
in the announcement of z/VM V4.4
to provide a variety of reports on system performance. Use the
Performance Toolkit to reduce data from the z/VM MONITOR and produce
reports and history files. The product has been enhanced and improved
in subsequent releases. To see a list of changes made in each level of
Performance Toolkit, refer to the function level entries in Quick
Links section on this page.
APAR VM64819
for z/VM 5.4.0 and z/VM 6.1.0 introduces updates for many problems uncovered during
internal IBM testing and while running Performance Toolkit on internal
IBM z/VM systems. For more information and abstracts of the problems
corrected refer to APAR VM64819
Considerations for RTM and PRF
Although the RealTime Monitor (RTM) and Performance Reporting Facility
(PRF)
optional features were supported in z/VM 4.4.0, IBM plans to make
future performance management enhancements primarily to the Performance
Toolkit for VM.
z/VM 4.4.0 was the last z/VM release in which the RTM and
PRF were available with z/VM.
-
The RTM optional feature
for z/VM V4.4 has been withdrawn from marketing
effective March 31, 2006
-
The PRF optional feature for z/VM V4.4 has been withdrawn from marketing
effective March 31, 2006.

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 V4.4.
Refer to the announcement letters for
z/VM V4.4 for details.
