| RMF provides its benefits through the operation of Postprocessing
and Online Monitoring functions. These are based on a set of data gatherers
and data services that enables access to all performance relevant data in
a z/OS environment. The four components are RMF Data Gatherer, RMF Sysplex
Data Services, Historical Data Reporting and Online Monitoring with RMF.
RMF data gatherer
The RMF data gatherer collects long-term and short-term performance data
of your z/OS systems. The data is saved in SMF records and for online
reporting in VSAM data sets.
RMF sysplex data services
The RMF sysplex data services allow RMF and other IBM and vendor
products to access and process the collected z/OS performance information
within a sysplex environment. RMF uses this function intensively with
its historical and online reporting function, thus providing a single
system image for performance management of a sysplex of z/OS systems.
Historical data reporting
The RMF Postprocessor is the central part for historical data reporting
on RMF data. It runs as a batch program and processes the SMF data collected
by the RMF data gatherer functions to create interval, duration, summary
and overview reports. Furthermore it allows you to combine SMF data from
all systems in a sysplex and generates sysplex-wide reports for shared
device utilization, coupling facility activity and workload activity.
The RMF Postprocessor has been extended with the RMF Spreadsheet Reporter,
running on your Windows® workstation. The Spreadsheet Reporter
gives you the ability to extract reports from RMF Postprocessor output
to convert them into a common spreadsheet format and allows your spreadsheet
application to use the RMF data. This helps you to integrate RMF data
easily into your business process, thus enhancing your productivity and
efficiency.
Online monitoring with RMF
RMF online reporting functions support real-time snapshot monitoring and
short-term performance analysis. The monitor functions use the RMF Sysplex
Data Server to give you a complete picture of your sysplex environment.
On your z/OS system, you can use the RMF online monitors, RMF Monitor
II and Monitor III, through a TSO/E and ISPF session. RMF Monitor II gives
you an immediate picture of the current resource consumptions and workload
utilization of your system, while RMF Monitor III provides short-term
analysis on the most current as well as historically saved system status
by the RMF Monitor III data gatherer. You can easily zoom into any system
and navigate freely between systems. If you want to take a closer look,
you can point and click to analyze any resource or workload behavior.
Both monitors are highly integrated and work together to ease your system
performance analysis.
But that's not all — you can also use RMF online monitoring functions
from your workstation. With RMF PM, you can monitor continuously your
z/OS systems from a central point. It runs on a Windows workstation
and allows you to monitor all your z/OS systems anywhere in the world
from one central location. RMF online monitoring today enables you to
control your systems in any situation — and gives you the confidence
to run your business at optimal speed.
The new JavaTM Edition of RMF PM is part of
OS/390 V2R10 RMF, but you can also download it from the Tools section
of the RMF Web site if you are running a previous version of RMF.

Technology Edition
No matter which platform you use, the ability to monitor any z/OS in
the world from a central point is a significant step forward towards a
comprehensive solution for operating system-independent performance management.
