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 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.

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.
