This IBM Redbooks publication provides a detailed look at Resource Measurement Facility (RMF), the IBM product designed to simplify management of single and multiple system workloads. RMF gathers data and creates reports that help system programmers and administrators to tune their system optimally, react quickly to system delays, and diagnose and remediate performance problems.
This book describes RMF functionality with special emphasis on the newest features, and also presents a review of the older, established components. Detailed instructions for setting up and customizing the components are provided. New features introduced are Spreadsheet Reporter, Distributed Data Server, Linux data gatherer, and Performance Monitor.
A high-level overview of performance analysis concepts is presented, along with a detailed discussion of performance metrics. This information is the foundation for an in-depth look at how RMF can be used to manage systems in the real world. Practical scenarios demonstrate how to use RMF to conduct overall performance evaluations and monitor batch and transactional workloads. The new reporting capabilities are illustrated with numerous examples, in particular those that support the latest workload licensing model, zAAP, UNIX System Services, WebSphere Application Server, and Linux.
